The flash memory is reprogrammable in-circuit, providing nonvolatile data storage and allowing field upgrades of the firmware. User firmware has complete control of all 32 Rev 1.0 SiM3 L1xx peripherals and may individually shut down and gate the clocks of any or all peripherals for power savings. The on-chip debugging interface (SWJ-DP) allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports inspection and modification of memory and registers, setting breakpoints, single stepping, and run and halt commands. All analog and digital peripherals are fully functional while debugging. Each device is specified for 1.8 to 3.8 V operation over the industrial temperature range (-40 to +85 C). The SiM3L1xx devices are available in 40-pin or 64-pin QFN, 64-pin or 80-pin TQFP, and 80-pin TFBGA packages. All package options are lead-free and RoHS compliant. See Table 5.1 for ordering information. A block diagram is included in Figure 4.1. Figure 4.1. Precision32TM SiM3L1xx Family Block Diagram Rev 1.0 33 SiM3L1xx 4.1. Power The SiM3L1xx devices include a dc-dc buck converter that can take an input from 1.8-3.8 V and create an output from 1.25-3.8 V. In addition, SiM3L1xx devices include three low dropout regulators as part of the LDO0 module: one LDO powers the analog subsystems, one LDO powers the flash and SRAM memory at 1.8 V, and one LDO powers the digital and core circuitry. Each of these regulators can be independently powered from the dc-dc converter or directly from the battery voltage, and their outputs are adjustable to conserve system power. SiM3L1xx devices also include a low power charge pump in the PMU module for use in low power modes (PM8) to further reduce the power consumption of the device. Figure 4.2 shows the power system configuration of these devices. Figure 4.2. SiM3L1xx Power 4.1.1. DC-DC Buck Converter (DCDC0) SiM3L1xx devices include an on-chip step-down dc-dc converter to efficiently utilize the energy stored in the battery, thus extending the operational life time. The dc-dc converter is a switching buck converter with a programmable output voltage that should be at least 0.45 V lower than the input battery voltage; if this criteria is not met and the converter can no longer operate, the output of the dc-dc converter automatically connects to the battery. The dc-dc converter can supply up to 100 mA and can be used to power the MCU and/or external devices in the system. The dc-dc converter has a built in voltage reference and oscillator and will automatically limit or turn off the switching activity in case the peak inductor current rises beyond a safe limit or the output voltage rises above the programmed target value. This allows the dc-dc converter output to be safely overdriven by a secondary power source (when available) in order to preserve battery life. When enabled, the dc-dc converter can source current into the output capacitor, but cannot sink current. The dc-dc converter includes the following features: Efficiently utilizes the energy stored in a battery, extending its operational lifetime. Input range: 1.8 to 3.8 V. Output range: 1.25 to 3.8 V in 50 mV (1.25-1.8 V) or 100 mV (1.8-3.8 V) steps. Supplies up to 100 mA. Includes a voltage reference and an oscillator. 34 Rev 1.0 SiM3 L1xx Supports synchronizing the regulator switching with the system clock. limits the peak inductor current if the load current rises beyond a safe limit. Automatically goes into bypass mode if the battery voltage cannot provide sufficient headroom. Sources current, but cannot sink current. 4.1.2. Three Low Dropout LDO Regulators (LDO0) The SiM3L1xx devices include one LDO0 module with three low dropout regulators. Each of these regulators have independent switches to select the battery voltage or the output of the dc-dc converter as the input to each LDO, and an adjustable output voltage. The LDOs consume little power and provide flexibility in choosing a power supply for the system. Each regulator can be independently adjusted between 0.8 and 1.9 V output. 4.1.3. Voltage Supply Monitor (VMON0) The SiM3L1xx devices include a voltage supply monitor that can monitor the main supply voltage. This module includes the following features: Main supply "VBAT Low" (VBAT below the early warning threshold) notification. Holds the device in reset if the main VBAT supply drops below the VBAT Reset threshold. The voltage supply monitor allows devices to function in known, safe operating conditions without the need for external hardware. Automatically 4.1.4. Power Management Unit (PMU) The Power Management Unit on the SiM3L1xx manages the power systems of the device. It manages the powerup sequence during power on and the wake up sources for PM8. On power-up, the PMU ensures the core voltages are a proper value before core instruction execution begins. The VDRV pin powers external circuitry from either the VBAT battery input voltage or the output of the dc-dc converter on VDC. The PMU includes an internal switch to select one of these sources for the VDRV pin. The PMU has a specialized VBAT-divided-by-2 charge pump that can power some internal modules while in PM8 to save power. The PMU module includes the following features: Provides the enable or disable for the analog power system, including the three LDO regulators. Up to 14 pin wake inputs can wake the device from Power Mode 8. The Low Power Timer, RTC0 (alarms and oscillator failure), Comparator 0, Advanced Capture Counter, LCD0 VBAT monitor, UART0, low power mode charge pump failure, and the RESET pin can also serve as wake sources for Power Mode 8. Controls which 4 kB RAM blocks are retained while in Power Mode 8. Provides a PMU_Asleep signal to a pin as an indicator that the device is in PM8. Specialized charge pump to reduce power consumption in PM8. Provides control for the internal switch between VBAT and VDC to power the VDRV pin for external circuitry. 4.1.5. Device Power Modes The SiM3L1xx devices feature seven low power modes in addition to normal operating mode. Several peripherals provide wake up sources for these low power modes, including the Low Power Timer (LPTIMER0), RTC0 (alarms and oscillator failure notification), Comparator 0 (CMP0), Advanced Capture Counter (ACCTR0), LCD VBAT monitor (LCD0), UART0, low power mode charge pump failure, and PMU Pin Wake. In addition, all peripherals can have their clocks disabled to reduce power consumption whenever a peripheral is not being used using the clock control (CLKCTRL) registers. 4.1.5.1. Normal Mode (Power Mode 0) and Power Mode 4 Normal Mode and Power Mode 4 are fully operational modes with code executing from flash memory. PM4 is the same as Normal Mode, but with the clocks operating at a lower speed. This enables power to be conserved by reducing the LDO regulator outputs. Rev 1.0 35 SiM3L1xx 4.1.5.2. Power Mode 1 and Power Mode 5 Power Mode 1 and Power Mode 5 are fully operational modes with code executing from RAM. PM5 is the same as PM1, but with the clocks operating at a lower speed. This enables power to be conserved by reducing the LDO regulator outputs. Compared with the corresponding flash operational mode (Normal or PM4), the active power consumption of the device in these modes is reduced. Additionally, at higher speeds in PM1, the core throughput can also be increased because RAMdoesnot require additional wait states that reduce the instruction fetch speed. 4.1.5.3. Power Mode 2 and Power Mode 6 In Power Mode 2 and Power Mode 6, the core halts and the peripherals continue to run at the selected clock speed. PM6 is the same as PM2, but with the clocks operating at a lower speed. This enables power to be conserved by reducing the LDO regulator outputs. To place the device in PM2 or PM6, the core should execute a wait-for-interrupt (WFI) or wait-for-event (WFE) instruction. If the WFI instruction is called from an interrupt service routine, the interrupt that wakes the device from PM2 or PM6 must be of a sufficient priority to be recognized by the core. It is recommended to perform both a DSB (Data Synchronization Barrier) and an ISB (Instruction Syncronization Barrier) operation prior to the WFI to ensure all bus accesses complete. When operating from the LFOSC0, PM6 can achieve similar power consumption to PM3, but with faster wake times and the ability to wake on any interrupt. 4.1.5.4. Power Mode 3 In Power Mode 3 the core and peripheral clocks are halted. The available sources to wake from PM3 are controlled by the Power Management Unit (PMU). A special Fast Wake option allows the core to wake faster by keeping the LFOSC0 or RTC0 clock active. Because the current consumption of these blocks is minimal, it is recommended to use the fast wake option. Before entering PM3, the DMA controller should be disabled, and the desired wake source(s) should be configured in the PMU. The SLEEPDEEP bit in the ARM System Control Register should be set, and the PMSEL bit in the CLKCTRL0_CONFIG register should be cleared to indicate that PM3 is the desired power mode. For fast wake, the core clocks (AHB and APB) should be configured to run from the LPOSC, and the PM3 Fast wake option and clock source should be selected in the PM3CN register. The device will enter PM3 on a WFI or WFE instruction. If the WFI instruction is called from an interrupt service routine, the interrupt that wakes the device from PM3 must be of a sufficient priority to be recognized by the core. It is recommended to perform both a DSB (Data Synchronization Barrier) and an ISB (Instruction Synchronization Barrier) operation prior to the WFI to ensure all bus access is complete. 4.1.5.5. Power Mode 8 In Power Mode 8, the core and most peripherals are completely powered down, but all registers and selected RAM blocks retain their state. The LDO regulators are disabled, so all active circuitry operates directly from VBAT. Alternatively, the PMU has a specialized VBAT-divided-by-2 charge pump that can power some internal modules while in PM8 to save power. The fully operational functions in this mode are: LPTIMER0 , RTC0, UART0 running from RTC0TCLK, PMU Pin Wake, the advanced capture counter, and the LCD controller. This mode provides the lowest power consumption for the device, but requires an appropriate wake up source or reset to exit. The available wake up or reset sources to wake from PM8 are controlled by the Power Management Unit (PMU). The available wake up sources are: Low Power Timer (LPTIMER0), RTC0 (alarms and oscillator failure notification), Comparator 0 (CMP0), advanced capture counter (ACCTR0), LCD VBAT monitor (LCD0), UART0, low power mode charge pump failure, and PMU Pin Wake. The available reset sources are: RESET pin, VBAT supply monitor, Comparator 0, Comparator 1, low power mode charge pump failure, RTC0 oscillator failure, or a PMU wake event. Before entering PM8, the desired wake source(s) should be configured in the PMU. The SLEEPDEEP bit in the ARM System Control Register should be set, and the PMSEL bit in the CLKCTRL0_CONFIG register should be set to indicate that PM8 is the desired power mode. The device will enter PM8 on a WFI or WFE instruction, and remain in PM8 until a reset configured by the PMU occurs. It is recommended to perform both a DSB (Data Synchronization Barrier) and an ISB (Instruction Synchronization Barrier) operation prior to the WFI to ensure all bus access is complete. 36 Rev 1.0 SiM3 L1xx 4.1.5.6. Power Mode Summary The power modes described above are summarized in Table 4.1. Table 3.2 and Table 3.3 provide more information on the power consumption and wake up times for each mode. Table 4.1. SiM3L1xx Power Modes Mode Normal Description Power Mode 1 (PM1) Power Mode 2 (PM2) Power Mode 3 (PM3) Power Mode 4 (PM4) Core operating at full speed Code executing from flash Full device operation Core operating at full speed Code executing from RAM Full device operation Higher CPU bandwidth than PM0 (RAM can operate with zero wait states at any frequency) Core halted AHB, APB and all peripherals operational at full speed Fast wakeup from any interrupt source All clocks to core and peripherals stopped Faster wake enabled by keeping LFOSC0 or RTC0TCLK active Wake on any wake source or reset source defined in the PMU Core operating at low speed Code executing from flash Same capabilities as PM0, operating at lower speed Lower clock speed enables lower LDO output settings to save power Power Mode 5 (PM5) Notes Core operating at low speed Code executing from RAM Core halted AHB, APB and all peripherals operational at low speed Power Mode 6 (PM6) Power Mode 8 (PM8) Low power sleep LDO regulators are disabled and all active circuitry operates directly from VBAT The following functions are available: ACCTR0, RTC0, UART0 running from RTC0TCLK, LPTIMER0, port match, and the LCD controller Register and RAM state retention Rev 1.0 Same capabilities as PM1, operating at lower speed Lower clock speed enables lower LDO output settings to save power Same capabilities as PM2, operating at lower speed Lower clock speed enables lower LDO output settings to save power When running from LFOSC0, power is similar to PM3, but the device wakes much faster Lowest power consumption Wake on any wake source or reset source defined in the PMU 37 SiM3L1xx 4.1.6. Process/Voltage/Temperature Monitor (TIMER2 and PVTOSC0) The Process/Voltage/Temperature monitor consists of two modules (TIMER2 and PVTOSC0) designed to monitor the digital circuit performance of the SiM3L1xx device. The PVT oscillator (PVTOSC0) consists of two oscillators, one operating from the memory LDO and one operating from the digital LDO. These oscillators have two independent speed options and provide the clocks for two 16-bit timers in the TIMER2 module using the EX input. By monitoring the resulting counts of the TIMER2 timers, firmware can monitor the current device performance and increase the scalable LDO regulator (LDO0) output voltages as needed or decrease the output voltages to save power. The PVT monitor has the following features: Two separate oscillators and timers for the memory and digital logic voltage domains. Two oscillator output divider settings. Provides a method for monitoring digital performance to allow firmware to adjust the scalable LDO regulator output voltages to the lowest level possible, saving power. 38 Rev 1.0 SiM3 L1xx 4.2. I/O 4.2.1. General Features The SiM3L1xx ports have the following features: 5 V tolerant. Push-pull or open-drain output modes to the VIO or VIORF voltage level. Analog or digital modes. Option for high or low output drive strength. Port Match allows the device to recognize a change on a port pin value. Internal pull-up resistors are enabled or disabled on a port-by-port basis. Two external interrupts with up to 16 inputs each provide monitoring capability for external signals. Internal Pulse Generator Timer (PB0 only) to generate simple square waves and pulses. 4.2.2. Crossbar The SiM3L1xx devices have one crossbar with the following features: Flexible peripheral assignment to port pins. Pins can be individually skipped to move peripherals as needed for design or layout considerations. The crossbar has a fixed priority for each I/O function and assigns these functions to the port pins. When a digital resource is selected, the least-significant unassigned port pin is assigned to that resource. If a port pin is assigned, the crossbar skips that pin when assigning the next selected resource. Additionally, the crossbar will skip port pins whose associated bits in the PBSKIPEN registers are set. This provides flexibility when designing a system: pins involved with sensitive analog measurements can be moved away from digital I/O, and peripherals can be moved around the chip as needed to ease layout constraints. Rev 1.0 39 SiM3L1xx 4.3. Clocking The SiM3L1xx devices have two system clocks: AHB and APB. The AHB clock services memory peripherals and is derived from one of seven sources: the RTC timer clock (RTC0TCLK), the Low Frequency Oscillator, the Low Power Oscillator, the divided Low Power Oscillator, the External Oscillator, the PLL0 Oscillator, and the VIORFCLK pin input. In addition, a divider for the AHB clock provides flexible clock options for the device. The APB clock services data peripherals and is synchronized with the AHB clock. The APB clock can be equal to the AHB clock or set to the AHB clock divided by two. The Clock Control module on SiM3L1xx devices allows the AHB and APB clocks to be turned off to unused peripherals to save system power. Any registers in a peripheral with disabled clocks will be unable to be accessed until the clocks are enabled. Most peripherals have clocks off by default after a power-on reset. Figure 4.3. SiM3L1xx Clocking 40 Rev 1.0 SiM3 L1xx 4.3.1. PLL (PLL0) The PLL module consists of a dedicated Digitally-Controlled Oscillator (DCO) that can be used in Free-Running mode without a reference frequency, Frequency-Locked to a reference frequency, or Phase-Locked to a reference frequency. The reference frequency for Frequency-Lock and Phase-Lock modes can use one of multiple sources (including the external oscillator) to provide maximum flexibility for different application needs. Because the PLL module generates its own clock, the DCO can be locked to a particular reference frequency and then moved to Free-Running mode to reduce system power and noise. The PLL module includes the following features: Three output ranges with output frequencies ranging from 23 to 50 MHz. Multiple reference frequency inputs, including the RTC0 oscillator, Low Power Oscillator, and external oscillator. Three output modes: Free-Running Digitally-Controlled Oscillator, Frequency-Locked, and Phase-Locked. Able to sense the rising edge or falling edge of the reference source. DCO frequency LSB dithering to provide finer average output frequencies. Spectrum spreading to reduce generated system noise. Low jitter and fast lock times.\ All output frequency updates (including dithering and spectrum spreading) can be temporarily suspended using the STALL bit during noise-sensitive measurements. 4.3.2. Low Power Oscillator (LPOSC0) The Low Power Oscillator is the default AHB oscillator on SiM3L1xx devices and enables or disables automatically, as needed. The default output frequency of this oscillator is factory calibrated to 20 MHz, and a divided 2.5 MHz version of this clock is also available as an AHB clock source. The Low Power Oscillator has the following features: 20 MHz and divided 2.5 MHz frequencies available for the AHB clock. Automatically starts and stops as needed. 4.3.3. Low Frequency Oscillator (LFOSC0) The low frequency oscillator (LFOSC) provides a low power internal clock source for the RTC0 timer and other peripherals on the device. No external components are required to use the low frequency oscillator, and the RTC1 and RTC2 pins do not need to be shorted together. The Low Frequency Oscillator has the following features: 16.4 kHz output frequency. 4.3.4. External Oscillators (EXTOSC0) The EXTOSC0 external oscillator circuit may drive an external crystal, ceramic resonator, capacitor, or RC network. A CMOS clock may also provide a clock input. The external oscillator output may be selected as the AHB clock or used to clock other modules independent of the AHB clock selection. The External Oscillator control has the following features: Support for external crystal, resonator, RC, C, or CMOS oscillators. Support for external CMOS frequencies from 10 kHz to 50 MHz. Support for external crystal frequencies from 10 kHz to 25 MHz. Various drive strengths for flexible crystal oscillator support. Internal frequency divide-by-two option available. Rev 1.0 41 SiM3L1xx 4.4. Integrated LCD Controller (LCD0) SiM3L1xx devices contain an LCD segment driver and on-chip bias generation that supports static, 2-mux, 3-mux and 4-mux LCDs with 1/2 or 1/3 bias. The on-chip charge pump with programmable output voltage allows software contrast control which is independent of the supply voltage. LCD timing is derived from the RTC timer clock (RTC0TCLK) to allow precise control over the refresh rate. The SiM3L1xx devices use registers to store the enabled/disabled state of individual LCD segments. All LCD waveforms are generated on-chip based on the contents of these registers with flexible waveform control to reduce power consumption wherever possible. An LCD blinking function is also supported on a subset of LCD segments. The LCD0 module has the following features: Up to 40 segment pins and 4 common pins. Supports LCDs with 1/2 or 1/3 bias. Includes an on-chip charge pump with programmable output that allows firmware to control the contrast independent of the supply voltage. The RTC timer clock (RTC0TCLK) determines the LCD timing and refresh rate. All LCD waveforms are generated on-chip based on the contents of the LCD0 registers with flexible waveform control. LCD segments can be placed in a discharge state for a configurable number of RTC clock cycles before switching to the next state to reduce power consumption due to display loading. Includes a VBAT monitor that can serve as a wakeup source for Power Mode 8. Supports four hardware auto-contrast modes: bypass, constant, minimum, and auto-bypass. Supports hardware blinking for up to 8 segments. 42 Rev 1.0 SiM3 L1xx 4.5. Data Peripherals 4.5.1. 10-Channel DMA Controller The DMA facilitates autonomous peripheral operation, allowing the core to finish tasks more quickly without spending time polling or waiting for peripherals to interrupt. This helps reduce the overall power consumption of the system, as the device can spend more time in low-power modes. The DMA controller has the following features: Utilizes ARM PrimeCell uDMA architecture. Implements 10 channels. DMA crossbar supports DTM0, DTM1, DTM2, SARADC0, IDAC0, I2C0, SPI0, SPI1, USART0, AES0, ENCDEC0, EPCA0, external pin triggers, and timers. Supports primary, alternate, and scatter-gather data structures to implement various types of transfers. Access allowed to all AHB and APB memory space. 4.5.2. Data Transfer Managers (DTM0, DTM1, DTM2) The Data Transfer Manager is a module that collects DMA request signals from various peripherals and generates a series of master DMA requests based on a state-driven configuration. This master request drives a set of DMA channels to perform functions such as assembling and transferring communication packets to external devices. This capability saves power by allowing the core to remain in a low power mode during complex transfer operations. A combination of simple and peripheral scatter-gather DMA configurations can be used to perform complex operations while reducing memory requirements. The DTM acts as a side channel for the peripheral's DMA control signals. When active, it manages the DMA control signals for the peripherals. When the DTMn module is inactive, the peripherals communicate directly to the DMA module. The DTMn module has the following features: State descriptions stored in RAM with up to 15 states supported per module. Supports up to 15 source peripherals and up to 15 destination peripherals per module, in addition to memory or peripherals that do not require a data request. Includes error detection and an optional transfer timeout. Includes notifications for state transitions. 4.5.3. 128/192/256-bit Hardware AES Encryption (AES0) The basic AES block cipher is implemented in hardware. The integrated hardware support for Cipher Block Chaining (CBC) and Counter (CTR) algorithms results in identical performance, memory bandwidth, and memory footprint between the most basic Electronic Codebook (ECB) algorithm and these more complex algorithms. This hardware accelerator translates to more core bandwidth available for other functions or a power savings for lowpower applications. The AES module includes the following features: Operates on 4-word (16-byte) blocks. Supports key sizes of 128, 192, and 256 bits for both encryption and decryption.

Hardware acceleration for Electronic Codebook (ECB), Cipher-Block Chaining (CBC), and Counter (CTR) algorithms utilizing integrated counterblock generation and previous-block caching. Rev 1.0 43 SiM3L1xx 4.5.4. 16/32-bit Enhanced CRC (ECRC0) The ECRC module is designed to provide hardware calculations for flash memory verification and communications protocols. In addition to calculating a result from direct writes from firmware, the ECRC module can automatically snoop the APB bus and calculate a result from data written to or read from a particular peripheral. This allows for an automatic CRC result without directly feeding data through the ECRC module. The supported 32-bit polynomial is 0x04C11DB7 (IEEE 802.3). The 16-bit polynomial is fully programmable. The ECRC module includes the following features: Support for a programmable 16-bit polynomial and one fixed 32-bit polynomial. Byte-level bit reversal for the CRC input.

Support for DMA writes using firmware request mode. 4.5.5. Encoder / Decoder (ENCDEC0) The encoder / decoder module supports Manchester and Three-out-of-Six encoding and decoding from either firmware or DMA operations. This module has the following features: Supports Manchester and Three-out-of-Six encoding and decoding. Automatic flag clearing when writing the input or reading the output data registers. Writing to the input data register automatically initiates an encode or decode operation. Optional output in one's complement format. Hardware error detection for invalid input data during decode operations, which helps reduce power consumption and packet turn-around time. Flexible byte swapping on the input or output data. 44 Rev 1.0 SiM3 L1xx 4.6. Counters/Timers 4.6.1. 32-bit Timer (TIMER0, TIMER1, TIMER2) Each timer module is independent, and includes the following features: Operation as a single 32-bit or two independent 16-bit timers.

TIMER2 does not support the standard input/output features of TIMER0 and TIMER1. The TIMER2 EX signal is internally connected to the outputs of the PVTOSC0 oscillators. TIMER2 can use any of the counting modes that use EX as an input, including up/down mode, edge capture mode, and pulse capture mode. The TIMER2 CT signal is disconnected. 4.6.2. Enhanced Programmable Counter Array (EPCA0) The Enhanced Programmable Counter Array (EPCA) module is a timer/counter system allowing for complex timing or waveform generation. Multiple modules run from the same main counter, allowing for synchronous output waveforms. This module includes the following features: Three sets of channel pairs (six channels total) capable of generating complementary waveforms. Center- and edge-aligned waveform generation. Programmable dead times that ensure channel pairs are never active at the same time. Programmable clock divisor and multiple options for clock source selection. Waveform update scheduling. Option to function while the core is inactive. Multiple synchronization triggers. Pulse-Width Modulation (PWM) waveform generation. Rev 1.0 45 SiM3L1xx 4.6.3. Real-Time Clock (RTC0) The RTC module includes a 32-bit timer that allows up to 36 hours of independent time-keeping when used with a 32.768 kHz watch crystal. The RTC provides three alarm events in addition to a missing clock event, which can also function as interrupt, reset, or wakeup sources on SiM3L1xx devices. The RTC module includes internal loading capacitors that are programmable to 16 discrete levels, allowing compatibility with a wide range of crystals. The RTC timer clock can be buffered and routed to a port bank pin to provide an accurate, low frequency clock to other devices while the core is in its lowest power down mode. The module also includes a low power internal low frequency oscillator that reduces low power mode current and is available for other modules to use as a clock source. The RTC module includes the following features: 32-bit timer (supports up to 36 hours) with three separate alarms. Option for one alarm to automatically reset the RTC timer. Missing clock detector. Can be used with the internal Low Frequency Oscillator or with an external 32.768 kHz crystal (no additional resistors or capacitors necessary). Programmable internal loading capacitors support a wide range of external 32.768 kHz crystals. The RTC timer clock (RTC0CLK) can be buffered and routed to an I/O pin to provide an accurate, low frequency clock to other devices while the core is in its lowest power down mode. The RTC module can be powered from the low power mode charge pump for lowest possible power consumption while in PM8. 4.6.4. Low Power Timer (LPTIMER0) The Low Power Timer (LPTIMER) module runs from the RTC timer clock (RTC0CLK), allowing the LPTIMER to operate even if the AHB and APB clocks are disabled.

Watchdog Timer (WDTIMER0) The WDTIMER module includes a 16-bit timer, a programmable early warning interrupt, and a programmable reset period. The timer registers are protected from inadvertent access by an independent lock and key interface. The watchdog timer runs from the low frequency oscillator (LFOSC0). The Watchdog Timer has the following features: Programmable timeout interval. Optional interrupt to warn when the Watchdog Timer is nearing the reset trip value. Lock-out feature to prevent any modification until a system reset. 46 Rev 1.0 SiM3 L1xx 4.6.6. Low Power Mode Advanced Capture Counter (ACCTR0) The SiM3L1xx devices contain a low-power Advanced Capture Counter module that runs from the RTC0 clock domain and can be used with digital inputs, switch topology circuits (reed switches), or with LC resonant circuits. For switch topology circuits, the module charges one or two external lines by pulsing internal pull-up resistors and detecting whether the reed switch is open or closed. For LC resonant circuits, the inputs are periodically energized to produce a dampened sine wave and configurable discriminator circuits detect the resulting decay time-constant. The advanced capture counter has the following general features: Single or differential inputs supporting single, dual, and quadrature modes of operation.

Communications Peripherals 4.7.1. USART (USART0) The USART uses two signals (TX and RX) to communicate serially with an external device. In addition to these signals, the USART module can optionally use a clock (UCLK) or hardware handshaking (RTS and CTS). The USART module provides the following features: Independent transmitter and receiver configurations with separate 16-bit baud rate generators. Synchronous or asynchronous transmissions and receptions. Clock master or slave operation with programmable polarity and edge controls. Up to 5 Mbaud (synchronous or asynchronous, TX or RX, and master or slave) or 1 Mbaud Smartcard (TX or RX). Individual enables for generated clocks during start, stop, and idle states.

Smartcard ACK/NACK support. Parity error, frame error, overrun, and underrun detection. Multi-master and half-duplex support. Multiple loop-back modes supported. Multi-processor communications support. 4.7.2. UART (UART0) The low-power UART uses two signals (TX and RX) to communicate serially with an external device. The UART0 module can operate in PM8 mode by taking the clock directly from the RTC0 time clock (RTC0TCLK) and running from the low power mode charge pump. This will allow the system to conserve power while transmitting or receiving UART traffic. The UART supports standard baud-rates of 9600, 4800, 2400 and 1200 in this low power mode. The UART0 module provides the following features: Independent transmitter and receiver configurations with separate 16-bit baud rate generators. Asynchronous transmissions and receptions. Up to 5 Mbaud (TX or RX). Internal transmit and receive FIFOs with flush capability and support for byte, half-word, and word reads and writes. Data bit lengths from 5 to 9 bits. Programmable inter-packet transmit delays. Auto-baud detection with support for the LIN SYNC byte. Automatic parity generation (with enable). Automatic start and stop generation (with separate enables). Independent inversion correction for TX and RX signals. Parity error, frame error, overrun, and underrun detection. Half-duplex support. 48 Rev 1.0 SiM3 L1xx Multiple loop-back modes supported. Multi-processor communications support. Operates at 9600, 4800, 2400, or 1200 baud in Power Mode 8. 4.7.3. SPI (SPI0, SPI1) SPI is a 3- or 4-wire communication interface that includes a clock, input data, output data, and an optional select signal. The SPI0 and SPI1 modules include the following features: Supports 3- or 4-wire master or slave modes. Supports up to 10 MHz clock in master mode and 5 MHz clock in slave mode. Support for all clock phase and slave select (NSS) polarity modes. 16-bit programmable clock rate. Programmable MSB-first or LSB-first shifting. 8-byte FIFO buffers for both transmit and receive data paths to support high speed transfers. Support for multiple masters on the same data lines. In addition, the SPI modules include several features to support autonomous DMA transfers: Hardware NSS control. Programmable FIFO threshold levels. Configurable FIFO data widths. Master or slave hardware flow control for the MISO and MOSI signals. SPI1 is on fixed pins and supports additional flow control options using a fixed input (SPI1CTS). Neither SPI1 nor the flow control input are on the crossbar. 4.7.4. I2C (I2C0) The I2C interface is a two-wire, bi-directional serial bus. The clock and data signals operate in open-drain mode with external pull-ups to support automatic bus arbitration. Reads and writes to the interface are byte oriented with the I2C interface autonomously controlling the serial transfer of the data. Data can be transferred at up to 1/8th of the APB clock as a master or slave, which can be faster than allowed by the I2C specification, depending on the clock source used. A method of extending the clocklow duration is available to accommodate devices with different speed capabilities on the same bus. The I2C interface may operate as a master and/or slave, and may function on a bus with multiple masters. The I2C provides control of SDA (serial data), SCL (serial clock) generation and synchronization, arbitration logic, and start/ stop control and generation. The I2C0 module includes the following features: Standard (up to 100 kbps) and Fast (400 kbps) transfer speeds. Can operate down to APB clock divided by 32768 or up to APB clock divided by 8. Support for master, slave, and multi-master modes. Hardware synchronization and arbitration for multi-master mode. Clock low extending (clock stretching) to interface with faster masters. Hardware support for 7-bit slave and general call address recognition. Firmware support for 10-bit slave address decoding. Ability to disable all slave states. Programmable clock high and low period. Programmable data setup/hold times. Spike suppression up to 2 times the APB period. Rev 1.0 49 SiM3L1xx 4.8. Analog 4.8.1. 12-Bit Analog-to-Digital Converter (SARADC0) The SARADC0 module on SiM3L1xx devices implements the Successive Approximation Register (SAR) ADC architecture. The key features of the module are as follows: Single-ended 12-bit and 10-bit modes. Supports an output update rate of 250 k samples per second in 12-bit mode or 1 M samples per second in 10-bit mode. Operation in low power modes at lower conversion speeds. Selectable asynchronous hardware conversion trigger with hardware channel select. DC offset cancellation. Automatic result notification with multiple programmable thresholds. Support for Burst Mode, which produces one set of accumulated data per conversion-start trigger with programmable power-on settling and tracking time. Non-burst mode operation can also automatically accumulate multiple conversions, but a conversion start is required for each conversion. Conversion complete, multiple conversion complete, and FIFO overflow and underflow flags and interrupts supported. Flexible output data formatting. Sequencer allows up to eight sources to be automatically scanned using one of four channel characteristic profiles without software intervention. Eight-word conversion data FIFO for DMA operations. Includes two internal references (1.65 V fast-settling, 1.2/2.4 V precision), support for an external reference, and support for an external signal ground. 4.8.2. 10-Bit Digital-to-Analog Converter (IDAC0) The IDAC module takes a digital value as an input and outputs a proportional constant current on a pin. The IDAC module includes the following features: 10-bit current DAC with support for four timer, up to seven external I/O and on demand output update triggers. Ability to update on rising, falling, or both edges for any of the external I/O trigger sources. Supports an output update rate greater than 600 k samples per second. Support for three full-scale output modes: 0.5 mA, 1.0 mA and 2.0 mA. Four-word FIFO to aid with high-speed waveform generation or DMA interactions. Individual FIFO overrun, underrun, and went-empty interrupt status sources. Support for multiple data packing formats, including: single 10-bit sample per word, dual 10-bit samples per word, or four 8-bit samples per word. Support for left- and right-justified data. 4.8.3. Low Current Comparators (CMP0, CMP1) The Comparators take two analog input voltages and output the relationship between these voltages (less than or greater than) as a digital signal. The low power comparator module includes the following features: Multiple sources for the positive and negative inputs, including VBAT, VREF, and 8 I/O pins. Two outputs available: a digital synchronous latched output and a digital asynchronous raw output. Programmable hysteresis and response time. Falling or rising edge interrupt options on the comparator output. 6-bit programmable reference divider. 50 Rev 1.0 SiM3 L1xx 4.9. Reset Sources Reset circuitry allows the controller to be easily placed in a predefined default condition. On entry to this reset state, the following occur: The core halts program execution. Module registers are initialized to their defined reset values unless the bits reset only with a power-on reset. External port pins are forced to a known state. Interrupts and timers are disabled. AHB peripheral clocks to flash and RAM are enabled. Clocks to all APB peripherals other than the Watchdog Timer and DMAXBAR are disabled. All registers are reset to the predefined values noted in the register descriptions unless the bits only reset with a power-on reset. The contents of RAM are unaffected during a reset; any previously stored data is preserved as long as power is not lost. The Port I/O latches are reset to 1 in open-drain mode. Weak pullups are enabled during and after the reset. For VBAT Supply Monitor and power-on resets, the RESET pin is driven low until the device exits the reset state. On exit from the reset state, the program counter (PC) is reset, and the system clock defaults to the internal lowpower oscillator. The Watchdog Timer is enabled with the low frequency oscillator as its clock source. Program execution begins at location 0x00000000. All RSTSRC0 registers may be locked against writes by setting the CLKRSTL bit in the LOCK0_PERIPHLOCK0 register to 1. The reset sources can also optionally reset individual modules, including the low power mode charge pump, UART0, LCD0, advanced capture counter (ACCTR0), and RTC0. Figure 4.4. SiM3L1xx Reset Sources Block Diagram Rev 1.0 51 SiM3L1xx 4.10. Security The peripherals on the SiM3L1xx devices have a register lock and key mechanism that prevents undesired accesses of the peripherals from firmware. Each bit in the PERIPHLOCKx registers controls a set of peripherals. A key sequence must be written to the KEY register to modify bits in PERIPHLOCKx. Any subsequent write to KEY will then inhibit accesses of PERIPHLOCKx until it is unlocked again through KEY. Reading the KEY register indicates the current status of the PERIPHLOCKx lock state. If a peripheral's registers are locked, all writes will be ignored. The registers can be read, regardless of the peripheral's lock state. Figure 4.5. SiM3L1xx Security Block Diagram 4.11. On-Chip Debugging The SiM3L1xx devices include JTAG and Serial Wire programming and debugging interfaces and ETM for instruction trace. The JTAG interface is supported on SiM3L1x7 devices only, and does not include boundary scan capabilites. The ETM interface is supported on SiM3L1x7, and SiM3L1x6 devices only. The JTAG and ETM interfaces can be optionally enabled to provide more visibility while debugging at the cost of using several Port I/O pins. Additionally, if the core is configured for Serial Wire (SW) mode and not JTAG, then the Serial Wire Viewer (SWV) is available to provide a single pin to send out TPIU messages. Serial Wire Viewer is supported on all SiM3Lxxx devices. Most peripherals on SiM3L1xx devices have the option to halt or continue functioning when the core halts in debug mode. 52 Rev 1.0 SiM3 L1xx 5. Ordering Information Figure 5.1.
