FUJITSU SEMICONDUCTOR DATA SHEET DS07-13717-3E 16-bit Proprietary Microcontroller CMOS F2MC-16LX MB90385 Series MB90387/387S/F387/F387S/MB90V495G DESCRIPTION MB90385 series devices are general-purpose high-performance 16-bit micro controllers designed for process control of consumer products, which require high-speed real-time processing. The devices of this series have the built-in full-CAN interface. The system, inheriting the architecture of F2MC* family, employs additional instruction ready for high-level languages, expanded addressing mode, enhanced multiply-divide instructions, and enriched bit-processing instructions. Furthermore, employment of 32-bit accumulator achieves processing of long-word data (32 bits). The peripheral resources of MB90385 series include the following: 8/10-bit A/D converter, UART (SCI), 8/16-bit PPG timer, 16-bit input-output timer (16-bit free-run timer, input capture 0, 1, 2, 3 (ICU)), and CAN controller. *: "F2MC", an abbreviation for FUJITSU Flexible Microcontroller, is a registered trademark of FUJITSU Ltd.

Latch-up may also occur when a voltage exceeding maximum rating is applied across Vcc and Vss. * Latch-up causes drastic increase of power current, which may lead to destruction of elements by heat. Extreme caution must be taken not to exceed maximum rating. * When turning on and off analog power source, take extra care not to apply an analog power voltages (AVcc and AVR) and analog input voltage that are higher than digital power voltage (Vcc). * Handling Unused Pins * Leaving unused input pins open may cause permanent destruction by malfunction or latch-up. Apply pull-up or pull-down process to the unused pins using resistors of 2 k or higher. Leave unused input pins open under output status, or process as input pins if they are under input status. * Using External Clock * When using an external clock, drive only X0 pin and leave X1 pin open. An example of using an external clock is shown below. * Using external clock X0 Open X1 MB90385 series * Notes When Using No Sub Clock * If an oscillator is not connected to X0A and X1A pin, apply pull-down resistor to X0A pin and leave X1A pin open. * About Power Supply Pins * If two or more Vcc and Vss exist, the pins that should be at the same potential are connected to each other inside the device. For reducing unwanted emissions and preventing malfunction of strobe signals caused by increase of ground level, however, be sure to connect the Vcc and Vss pins to the power source and the ground externally. * Pay attention to connect a power supply to Vcc and Vss of MB90385 series device in a lowest-possible impedance. * Near pins of MB90385 series device, connecting a bypass capacitor is recommended at 0.1 F across Vcc and Vss. * Crystal Oscillator Circuit * Noises around X0 and X1 pins cause malfunctions on a MB90385 series device. Design a print circuit so that X0 and X1 pins, an crystal oscillator (or a ceramic oscillator), and bypass capacitor to the ground become as close as possible to each other. Furthermore, avoid wires to X0 and X1 pins crossing each other as much as possible. * Print circuit designing that surrounds X0 and X1 pins with grounding wires, which ensures stable operation, is strongly recommended. * Caution on Operations during PLL Clock Mode * If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even when there is no external oscillator or external clock input is stopped. Performance of this operation, however, cannot be guaranteed. 11 MB90385 Series * Sequence of Turning on Power of A/D Converter and Applying Analog Input * Be sure to turn on digital power (Vcc) before applying signals to the A/D converter and applying analog input signals (AN0 to AN7 pins). * Be sure to turn off the power of A/D converter and analog input before turning off the digital power source. * Be sure not to apply AVR exceeding AVcc when turning on and off. (No problems occur if analog and digital power is turned on and off simultaneously.) * Handling Pins When A/D Converter is Not Used * If the A/D converter is not used, connect the pins under the following conditions: "AVcc=AVR=Vcc," and "AVss=Vss" * Note on Turning on Power * For preventing malfunctions on built-in step-down circuit, maintain a minimum of 50 s of voltage rising time (between 0.2 V and 2.7V) when turning on the power. * Stabilization of supply voltage * A sudden change in the supply voltage may cause the device to malfunction even within the specified VCC supply voltage operating range. Therefore, the VCC supply voltage should be stabilized. For reference, the supply voltage should be controlled so that VCC ripple variations (peak-to-peak values) at commercial frequencies (50 Hz to 60 Hz) fall below 10% of the standard VCC supply voltage and the coefficient of fluctuation does not exceed 0.1 V/ms at instantaneous power switching. 12 MB90385 Series BLOCK DIAGRAM X0,X1 RST X0A,X1A Clock control circuit CPU F2MC-16LX core Clock timer Time-base timer 16-bit free-run timer RAM Input capture (4ch) Prescaler SOT1 SCK1 SIN1 UART1 Internal data bus ROM/FLASH 16-bit PPG timer (2ch) CAN DTP/External interrupt IN0 to IN3 PPG0 to PPG3 RX TX INT4 to INT7 AVcc AVss AN0 to AN7 AVR 8/10-bit A/D converter (8ch) 16-bit reload timer (2ch) TIN0,TIN1 TOT0,TOT1 ADTG 13 MB90385 Series MEMORY MAP MB90385 series allows specifying a memory access mode "single chip mode." 1.

Note : When internal ROM is operating, F2MC-16LX allows viewing ROM data image on FF bank at upper-level of 00 bank. This function is called "mirroring ROM," which allows effective use of C compiler small model. F2MC-16LX assigns the same low order 16-bit address to FF bank and 00 bank, which allows referencing table in ROM without specifying "far" using pointer. For example, when accessing to "00C000H", ROM data at "FFC000H" is accessed actually. However, because ROM area of FF bank exceeds 48 Kbytes, viewing all areas is not possible on 00 bank image. Because ROM data of "FF4000H" to "FFFFFFH" is viewed on "004000H" to "00FFFFH" image, store a ROM data table in area "FF4000H" to "FFFFFFH." 14 MB90385 Series I/O MAP Register Address abbreviation

Watchdog Timer The watchdog timer is a 2-bit counter that uses time-base timer or clock timer as count clock. If the counter is not cleared within an interval time, CPU is reset. *Watchdog timer functions * The watchdog timer is a timer counter that prevents runaway of a program. Once a watchdog timer is activated, the counter of watchdog timer must always be cleared within a specified time of interval. If specified interval time elapses without clearing the counter of a watchdog timer, CPU resetting occurs. This is the function of a watchdog timer. * The interval time of a watchdog timer is determined by a clock cycle, which is input as a count clock. Watchdog resetting occurs between a minimum time and a maximum time specified. * The output target of a clock source is specified by the watchdog clock selection bit (WTC: WDCS) in the clock timer control register. * Interval time of a watchdog timer is specified by the time-base timer output selection bit/clock timer output selection bit (WDTC: WT1, WT0) in the watchdog timer control register. Interval timer of watchdog timer Min Max Clock cycle Min Max Clock cycle Approx. 4.61 ms 2 2 /HCLK Approx. 0.457 s Approx. 0.576 s 21229 /SCLK Approx. 14.33 ms Approx. 18.3 ms 216213 /HCLK Approx. 3.584 s Approx. 4.608 s 215212 /SCLK Approx. 57.23 ms Approx. 73.73 ms 218215 /HCLK Approx. 7.168 s Approx. 9.216 s 216213 /SCLK 14 Approx. 3.58 ms Approx. 458.75 ms Approx. 589.82 ms 11 221218 /HCLK Approx. 14.336 s Approx. 18.432 s 217214 /SCLK HCLK: Oscillation clock ( 4 MHz) , CSCLK: Sub clock (8.192 kHz) Notes: * If the time-base timer is cleared when watchdog timer count clock is used as time base timer output (carry-over signal), watchdog reset time may become longer. * When using the sub clock as machine clock, be sure to specify watchdog timer clock source selection bit (WDCS) in clock timer control register (WTC) at "0," selecting output of clock timer. 32 MB90385 Series * Watchdog timer block diagram Clock timer control register (WTC) Watchdog timer control register(WDTC) WRST ERST SRST WTE WT1 WT0 PONR Watchdog timer WDCS 2 Activate Reset occurs Shift to sleep mode Shift to time-base timer mode Shift to clock mode Shift to stop mode Counter clear control circuit Watchdog reset generation circuit 2-bit counter Count clock selector Internal reset generation circuit Clear 4 4 Time-base timer counter Main clock (dividing HCLK by 2) 21 22 28 29 210 25 26 27 211 212 213 214 215 216 217 218 28 210 211 212 213 214 215 Clock counter Sub clock SCLK 21 22 29 HCLK: Oscillation clock SCLK: Sub clock 33 MB90385 Series 4. 16-bit Input/Output Timer The 16-bit input/output timer is a compound module composed of 16-bit free-run timer, (1 unit) and input capture (2 units, 4 input pins).

Notes on A/D Converter Section Use the device with external circuits of the following output impedance for analog inputs: Recommended output impedance of external circuits are: Approx. 3.9 k or lower (4.5 V AVcc 5.5 V) (sampling period=2.00 s at 16-MHz machine clock), Approx. 11 k or lower (4.0 V AVcc < 4.5 V) (sampling period=8.0 s at 16-MHz machine clock). If an external capacitor is used, in consideration of the effect by tap capacitance caused by external capacitors and on-chip capacitors, capacitance of the external one is recommended to be several thousand times as high as internal capacitor. If output impedance of an external circuit is too high, a sampling period for an analog voltage may be insufficient. * Analog input circuit model R Analog input Comparator C MB90F387/S, MB90387/S 4.5 V AVCC 5.5 V R =: 2.35 k, C =: 36.4 pF 4.0 V AVCC < 4.5 V R =: 16.4 k, C =: 36.4 pF Note : Use the values in the figure only as a guideline. * About errors As [AVR-AVss] become smaller, values of relative errors grow larger. 8.
