DS60001234C-page 3 USB82514 1.0 INTRODUCTION The Microchip Automotive Grade USB 2.0 4-Port Hub is a low-power, OEM configurable, MTT (Multi- Transaction Translator) hub controller IC with 4 downstream ports for embedded USB solutions. It is designed, fabricated, tested, characterized and qualified for automotive applications. The 4-port hub is fully compliant with the USB 2.0 Specification. The USB82514 will attach to an upstream port as a full-speed hub or as a full-/hi-speed hub. The 4-port hub supports lowspeed, full-speed, and hi-speed (if operating as a hi-speed hub) downstream devices on all of the enabled downstream ports. All required resistors on the USB ports are integrated into the hub. This includes all series termination resistors on D+ and D- pins and all required pull-down and pull-up resistors on D+ and D- pins. The over-current sense inputs for the downstream facing ports have internal pull-up resistors. The USB82514 includes over 30 programmable features including: MultiTRAKTM Technology which utilizes a dedicated TT per port to maintain consistent full-speed data throughput regardless of the number of active downstream connections. MultiTRAK outperforms conventional USB 2.0 hubs with a single TT in USB full-speed data transfers. PortMap which provides flexible port mapping and disable sequences. The downstream ports of a USB82514 hub can be reordered or disabled in any sequence to support multiple platform designs with minimum effort. For any port that is disabled, the USB82514 automatically reorders the remaining ports to match the USB host controller's port numbering scheme. L1 L2 L3 L4 Card Reader PortSwap which adds per-port programmability to USB differential-pair pin locations. PortSwap allows direct alignment of USB signals (D+/D-) to connectors avoiding uneven trace length or crossing of the USB differential signals on the PCB. PHYBoost which enables four programmable levels of USB signal drive strength in downstream port transceivers. PHYBoost attempts to restore USB signal integrity that has been compromised by system level variables such as poor PCB layout, long cables, etc. The boost graphic shows an example of hi-speed USB eye diagrams before (PHYBoost at 0%) and after (PHYBoost at 12%) signal integrity restoration in a compromised system environment. The USB82514 is specifically tailored for use in automotive applications requiring automotive grade robustness starting with the comprehension of proprietary design for reliability techniques within the silicon IC itself as well as for the package design. Automotive qualified technologies and processes are used to fabricate the products with enhanced monitors to continuously drive improvements in accordance with our zero-dpm methodology. Product qualification is focused on customer expectations and exceeds many of the automotive reliability standards including AEC-Q100. Microchip automotive services are provided during the life of the product from a dedicated organization composed of operations, quality, and product support personnel specialized in meeting the requirements of the automotive customer. DS60001234C-page 4 2014-2017 Microchip Technology Inc. USB82514 1.1 OEM Selectable Features A default configuration is available in the USB82514 following a reset. This configuration may be sufficient for some applications. Strapping option pins make it possible to modify a limited sub-set of the configuration options. The USB82514 may also be configured by an external EEPROM or a microcontroller. When using the microcontroller interface, the hub appears as an SMBus slave device. If the hub is pin-strapped for external EEPROM configuration but no external EEPROM is present, then a value of `0' will be written to all configuration data bit fields (the hub will attach to the host with all `0' values). The USB82514 supports several OEM selectable features: * Optional OEM configuration via I2C EEPROM or via the industry standard SMBus interface from an external SMBus host or microcontroller, see Table 7-1, "Hub Configuration Options" to configure the serial port interface behavior via the CFG_SEL1 and CFG_SEL0 pins. * Compound device support (port is permanently hardwired to a downstream USB peripheral device), on a port-byport basis, see "Register 07h: Configuration Data Byte 2", bit COMPOUND. * Select Single-Transaction Translator (STT) or Multi-Transaction Translator (MTT), see "Register 06h: Configuration Data Byte 1", bit MTT_ENABLE. * Select over-current sensing and port power control on an individual (port-by-port) or ganged (all ports together) basis to match the OEM's choice of circuit board component selection, see "Register 06h: Configuration Data Byte 1", bits CURRENT_SNS and PORT_PWR. * Customize vendor ID, product ID, and device ID, see "Register 00h: Vendor ID (LSB)", "Register 01h: Vendor ID (MSB)", "Register 02h: Product ID (LSB)", "Register 03h: Product ID (MSB)", "Register 04h: Device ID (LSB)" and "Register 05h: Device ID (MSB)". * Easily configure as a 2, 3 or 4-Port Hub in common PCB layout, see "Register 0Ah: Port Disable for Self-Powered Operation" and "Register 0Bh: Port Disable for Bus-Powered Operation". * PortMap: Flexible port mapping and disable sequence. Ports can be disabled/reordered in any sequence to support multiple platforms with a single design. The hub will automatically reorder the remaining ports to match the host controller's numbering scheme, see "Register FBh: PortMap 12" and "Register FCh: PortMap 34". * PortSwap: Programmable USB differential-pair pin location. - Eases PCB layout by aligning USB signal lines directly to connectors, see "Register FAh: PortSwap". * PhyBoost: Programmable USB signal drive strength.

The signals are arranged in functional groups according to their associated interface. The "N" symbol in the signal name indicates that the active, or asserted, state occurs when the signal is at a low voltage level. When "N" is not present after the signal name, the signal is asserted when at the high voltage level. The terms assertion and negation are used exclusively. This is done to avoid confusion when working with a mixture of "active low" and "active high" signals. The term assert, or assertion, indicates that a signal is active, independent of whether that level is represented by a high or low voltage. The term negate, or negation, indicates that a signal is inactive.

The Microchip hub monitors VBUS_DET to determine when to assert the internal D+ pull-up resistor (signaling a connect event). When designing a detachable hub, this pin must be connected to the VBUS on the upstream port via a 2 to 1 voltage divider. For self-powered applications with a permanently attached host, this pin must be connected to 3.3 V (typically VDD33).

USB82514 7.0 CONFIGURATION OPTIONS 7.1 4-Port Hub Microchip's Automotive Grade USB 2.0 4-Port Hub is fully compliant to the Universal Serial Bus Specification available from the USB Implementer's Forum found at http://www.usb.org/developers/docs/ (Revision 2.0 from April 27, 2000 and the 12/7/2000 and 5/28/2002 Errata). Please refer to Chapter 11 (Hub Specification) for general details regarding hub operation and functionality. For performance reasons, the 4-Port Hub provides 1 Transaction Translator (TT) per port (defined as Multi-TT configuration), and each TT has 1512 bytes of periodic buffer space and 272 bytes of non- periodic buffer space (divided into 4 non-periodic buffers per TT), for a total of 1784 bytes of buffer space for each Transaction Translator. 7.1.1 HUB CONFIGURATION OPTIONS The Microchip hub supports a large number of features (some are mutually exclusive), and must be configured in order to correctly function when attached to a USB host controller. There are three principal ways to configure the hub: SMBus, EEPROM, or by internal default settings (with or without pin strapping option overrides). In all cases, the configuration method will be determined by the CFG_SEL1 and CFG_SEL0 pins immediately after RESET_N negation. If the SMBus or EEPROM is selected using the CFG_SEL pins, then the data read in from the EEPROM/SMBus will take precedence over the pin strapping options. If the internal default setting is selected, the options come from the internal ROM. These values can be selectively overridden using the pin strapping options. 7.1.2 SMBus OR EEPROM INTERFACE TABLE 7-1: HUB CONFIGURATION OPTIONS CFG_SEL1 CFG_SEL0 0 0 Internal default configuration * Strap options enabled * Self-powered operation enabled 0 1 Configured as an SMBus slave for external download of userdefined descriptors. * SMBus slave address 58 (0101100x) * Strap options disabled * All settings controlled by registers 1 0 Internal default configuration * Strap options enabled * Bus power operation 1 1 2-Wire I2C EEPROMS are supported * Strap options disabled * All settings controlled by registers 7.1.2.1 SMBUS OR EEPROM INTERFACE BEHAVIOR Power Switching Polarity The hub will only support active high power controllers. 7.1.3 VBus DETECT According to section 7.2.1 of the USB 2.0 Specification, a downstream port can never provide power to its D+ or D- pull up resistors unless the upstream port's VBUS is in the asserted (powered) state. The VBUS_DET pin on the hub monitors the state of the upstream VBUS signal and will not pull up the D+ resistor if VBUS is not active. If VBUS goes from an active to an inactive state (not powered), the hub will remove power from the D+ pull-up resistor within 10 seconds. 2014-2017 Microchip Technology Inc. DS60001234C-page 15 USB82514 7.2 EEPROM Interface The Microchip hub can be configured via a 2-wire (I2C) EEPROM (256x8). (Please see Table 7-1, "Hub Configuration Options" for specific details on how to enable configuration via an I2C EEPROM). When configured for EEPROM support, the internal state machine will read the external EEPROM for configuration data. The hub will then "attach" to the upstream USB host. Note: The hub does not have the capacity to write, or "Program," an external EEPROM. The hub only has the capability to read external EEPROMs. The external EEPROM will be read (even if it is blank or non-populated), and the hub will be "configured" with the values that are read. Each register has R/W capability. SMBUS and EEPROM Reset Values are 0x00. Reserved registers should be written to `0' unless otherwise specified. 7.2.1 INTERNAL REGISTER SET (COMMON TO EEPROM AND SMBus) Reg Addr Register Name Internal Default ROM 00h Vendor ID (LSB) 24h 01h Vendor ID (MSB) 04h 02h Product ID (LSB) 14h 03h Product ID (MSB) 25h 04h Device ID (LSB) A0h 05h Device ID (MSB) 80h 06h Configuration Data Byte 1 9Bh 07h Configuration Data Byte 2 20h 08h Configuration Data Byte 3 02h 09h Non-Removable Device 00h 0Ah Port Disable for Self-Powered Operation 00h 0Bh Port Disable for Bus-Powered Operation 00h 0Ch Max Power for Self-Powered Operation 01h 0Dh Max Power for Bus-Powered Operation 32h 0Eh Hub Controller Max Current for Self-Powered Operation 01h 0Fh Hub Controller Max Current for Bus-Powered Operation 32h 10h Power-on Time 32h 11h Language ID High 00h 12h Language ID Low 00h 13h Manufacturer String Length 00h 14h Product String Length 00h 15h Serial String Length 00h 16h-53h Manufacturer String 00h 54h-91h Product String 00h DS60001234C-page 16 2014-2017 Microchip Technology Inc.

USB82514 7.2.1.7 Register 06h: Configuration Data Byte 1 Bit Number Bit Name 7 SELF_BUS_PWR Description Self or Bus-Power: Selects between self and bus-powered operation. The hub is either self-powered (draws less than 2 mA of upstream bus power) or bus-powered (limited to a 100 mA maximum of upstream power prior to being configured by the host controller). When configured as a bus-powered device, the Microchip hub consumes less than 100 mA of current prior to being configured. After configuration, the buspowered Microchip hub (along with all associated hub circuitry, any embedded devices if part of a compound device, and 100 mA per externally available downstream port) must consume no more than 500 mA of upstream VBUS current. The current consumption is system dependent, and the OEM must ensure that the USB 2.0 specifications are not violated. When configured as a self-powered device, <1 mA of upstream VBUS current is consumed and all ports are available, with each port being capable of sourcing 500 mA of current. This field is set by the OEM using either the SMBus or EEPROM interface options. See description of the DYNAMIC bit (reg 07h, bit 7) for the self-/bus-power functionality when dynamic power switching is enabled. `0' = Bus-powered operation `1' = Self-powered operation Note: 6 Reserved 5 HS_DISABLE If dynamic power switching is enabled, this bit is ignored and the LOCAL_PWR pin is used to determine if the hub is operating from self or bus power. Reserved Hi-Speed Disable: Disables the capability to attach as either a Hi-/Full-speed device, and forces attachment as Full-speed only (i.e., no Hi-Speed support). `0' = Hi-/Full-Speed `1' = Full-Speed-Only (Hi-Speed is disabled!) 4 MTT_ENABLE Multi-TT enable: Enables one Transaction Translator per port operation. Selects between a mode where only one Transaction Translator is available for all ports (Single-TT), or each port gets a dedicated Transaction Translator (Multi-TT) {Note: The host may force Single-TT mode only}. `0' = Single TT for all ports `1' = One TT per port (multiple TT's supported) 2014-2017 Microchip Technology Inc. DS60001234C-page 19 USB82514 Bit Number Bit Name Description 3 EOP_DISABLE EOP Disable: Disables EOP generation of EOF1 when in Full-Speed mode. During FS operation only, this permits the hub to send EOP if no downstream traffic is detected at EOF1. See Section 11.3.1 of the USB 2.0 Specification for additional details. Note: generation of an EOP at the EOF1 point may prevent a host controller (operating in FS mode) from placing the USB bus in suspend. `0' = EOP generation is normal `1' = EOP generation is disabled 2:1 CURRENT_SNS Over-current Sense: Selects current sensing on a port-by-port basis, all ports ganged, or none (only for bus-powered hubs). The ability to support current sensing on a port or ganged basis is hardware implementation dependent. `00' = Ganged sensing (all ports together) `01' = Individual port-by-port `1x' = Over-current sensing not supported (must only be used with bus-powered configurations!) 0 PORT_PWR Port Power Switching: Enables power switching on all ports simultaneously (ganged), or port power is individually switched on and off on a port-by-port basis (individual). The ability to support power enabling on a port or ganged basis is hardware implementation dependent. `0' = Ganged switching (all ports together) `1' = Individual port-by-port switching 7.2.1.8 Register 07h: Configuration Data Byte 2 Bit Number Bit Name Description 7 DYNAMIC Dynamic Power Switching Enable: Controls the ability of the hub to automatically change from self-powered operation to bus-powered operation if the local power source is removed or is unavailable (and from bus-powered to self-powered if the local power source is restored). {Note: If the local power source is available, the hub will always switch to self-powered operation.} When dynamic power switching is enabled, the hub detects the availability of a local power source by monitoring the external LOCAL_PWR pin. If the hub detects a change in power source availability, the hub immediately disconnects and removes power from all downstream devices and disconnects the upstream port. The hub will then re-attach to the upstream port as either a buspowered hub (if local-power is unavailable) or a self-powered hub (if local power is available). `0' = No dynamic auto-switching `1' = Dynamic auto-switching capable 6 Reserved DS60001234C-page 20 Reserved 2014-2017 Microchip Technology Inc.

The internal memory (address range 00h-FEh) is "write-protected" to prevent unintentional data corruption. 7.2.2 I2C EEPROM The I2C EEPROM interface implements a subset of the I2C Master Specification (Please refer to the Philips Semiconductor Standard I2C-Bus Specification for details on I2C bus protocols). The hub's I2C EEPROM interface is designed to attach to a single "dedicated" I2C EEPROM, and conforms to the Standard-mode I2C Specification (100 kbit/s transfer rate and 7-bit addressing) for protocol and electrical compatibility. Note: 7.2.2.1 Extensions to the I2C Specification are not supported. The hub acts as the master and generates the serial clock SCL, controls the bus access (determines which device acts as the transmitter and which device acts as the receiver), and generates the START and STOP conditions. Implementation Characteristics The hub will only access an EEPROM using the sequential read protocol. 7.2.2.2 Pull-Up Resistor The circuit board designer is required to place external pull-up resistors (10 k recommended) on the SDA/SMBDATA/ NON_REM1 and SCL/SMBCLK/CFG_SEL0 lines (per SMBus 1.0 Specification, and EEPROM manufacturer guidelines) to VDD in order to assure proper operation. 7.2.2.3 I2C EEPROM Slave Address Slave address is 1010000. Note: 7.2.3 10-bit addressing is NOT supported. IN-CIRCUIT EEPROM PROGRAMMING The EEPROM can be programmed via ATE (Automatic Test Equipment) by pulling RESET_N low (which tri-states the hub's EEPROM interface and allows an external source to program the EEPROM). 2014-2017 Microchip Technology Inc. DS60001234C-page 31 USB82514 7.3 SMBus Slave Interface Instead of loading user-defined descriptor data from an external EEPROM, the Microchip hub can be configured to receive a code load from an external processor via an SMBus interface. The SMBus interface shares the same pins as the EEPROM interface; if CFG_SEL1 & CFG_SEL0 activates the SMBus interface, external EEPROM support is no longer available (and the user-defined descriptor data must be downloaded via the SMBus). The Microchip hub waits indefinitely for the SMBus code load to complete and only "appears" as a newly connected device on USB after the code load is completed. The hub's SMBus implementation is a slave-only SMBus device. The implementation only supports read block and write block protocols. The hub responds to other protocols as described in Section 7.3.2, "Invalid Protocol Response Behavior," on page 33. Reference to the System Management Bus Specification, Rev 1.0. The SMBus interface is used to read and write the registers in the device. The register set is shown in Section 7.2.1, "Internal Register Set (Common to EEPROM and SMBus)," on page 16. 7.3.1 BUS PROTOCOLS Typical write block and read block protocols are shown below. Register accesses are performed using 7-bit slave addressing, an 8-bit register address field, and an 8-bit data field. The shading indicates the hub driving data on the SMBDATA line; otherwise, host data is on the SDA/SMBDATA/NON_REM1 line. The slave address is the unique SMBus Interface Address for the hub that identifies it on SMBus. The register address field is the internal address of the register to be accessed. The register data field is the data that the host is attempting to write to the register or the contents of the register that the host is attempting to read. Note: Data bytes are transferred MSB first. 7.3.1.1 Block Read/Write The block write begins with a slave address and a write condition. After the command code, the host issues a byte count, which describes how many more bytes will follow in the message. If a slave had 20 bytes to send, the first byte would be the number 20 (14h), followed by the 20 bytes of data. The byte count may not be 0. A block read or write is allowed to transfer a maximum of 32 data bytes. Note: For the following SMBus tables: Denotes Master-to-Slave FIGURE 7-1: Denotes Slave-to-Master BLOCK WRITE 1 7 1 1 S Slave Address Wr A 8 1 Register Address A ... 8 1 8 1 8 1 8 1 1 Byte Count = N A Data byte 1 A Data byte 2 A Data byte N A P Block Write DS60001234C-page 32 2014-2017 Microchip Technology Inc. USB82514 7.3.1.2 Block Read A block read differs from a block write in that the repeated start condition exists to satisfy the I2C specification's requirement for a change in the transfer direction. FIGURE 7-2: 1 S BLOCK READ 7 Slave Address 1 1 8 1 1 7 1 1 Wr A Register Address A S Slave Address Rd A ... 8 1 8 1 8 1 8 1 1 Byte Count = N A Data byte 1 A Data byte 2 A Data byte N A P Block Read 7.3.2 INVALID PROTOCOL RESPONSE BEHAVIOR Registers accessed with an invalid protocol are not updated. A register is only updated following a valid protocol. The only valid protocols are write block and read block, which are described above. The hub only responds to the hardware selected Slave Address (0101100x). Attempting to communicate with the hub over SMBus with an invalid slave address or invalid protocol results in no response, and the SMBus Slave Interface returns to the idle state. The only valid registers that are accessible by the SMBus slave address are the registers defined in the Registers Section. The hub does not respond to undefined registers. 7.3.3 GENERAL CALL ADDRESS RESPONSE The hub does not respond to a general call address of 0000_000b. 7.3.4 SLAVE DEVICE TIME-OUT According to the SMBus Specification, version 1.0 devices in a transfer can abort the transfer in progress and release the bus when any single clock low interval exceeds 25 ms (TTIMEOUT, MIN). Devices that have detected this condition must reset their communication and be able to receive a new START condition no later than 35 ms (TTIMEOUT, MAX). Note: 7.3.5 Some simple devices do not contain a clock low drive circuit; this simple kind of device typically resets its communications port after a start or stop condition. The slave device time-out must be implemented. STRETCHING THE SCLK SIGNAL The hub supports stretching of the SCLK by other devices on the SMBus. The hub does not stretch the SCLK. 2014-2017 Microchip Technology Inc. DS60001234C-page 33 USB82514 SMBus/I2C TIMING 7.3.6 The SMBus slave interface complies with the SMBus AC Timing Specification.

Reads to undefined registers return to 00h. Writes to undefined registers have no effect and do not return an error. 7.3.7.2 Reserved Registers Only a `0' should be written to all reserved registers or bits. DS60001234C-page 34 2014-2017 Microchip Technology Inc. USB82514 7.4 Default Configuration Option To configure the hub in its default configuration, strap the CFG_SEL1 to 0 and CFG_SEL0 to 0. This configures the hub to the internal defaults and enables the strapping options. (Please see Section 7.2.1, "Internal Register Set (Common to EEPROM and SMBus)" for the list of the default values.) For specific pin strapping options, please see Chapter 6.0, Pin Descriptions for instructions on how to modify the default values. Options include port disable and non-removable pin strapping. 7.5 Reset There are two different resets that the hub experiences. One is a hardware reset via the external RESET_N pin and the second is via the USB Bus Reset. 7.5.1 EXTERNAL HARDWARE RESET_N A valid hardware reset is defined as assertion of RESET_N for a minimum of 1s after all power supplies are within operating range. While reset is asserted, the hub (and its associated external circuitry) consumes less than 500 A of current from the upstream USB power source. Assertion of RESET_N (external pin) causes the following: 1. 2. 3. 4. 5. 6. All downstream ports are disabled, and PRTPWR power to downstream devices is removed. The PHYs are disabled, and the differential pairs will be in a high-impedance state. All transactions immediately terminate; no states are saved. All internal registers return to the default state (in most cases, 00(h)). The external crystal oscillator is halted. The PLL is halted. The hub is "operational" 500 s after RESET_N is negated. Once operational, the hub configures itself based on the settings of pins CFG_SEL[1:0]. See Table 7-1, "Hub Configuration Options," on page 15.

For SelfPowered configurations, t3 MAX is not applicable and the time to load the configuration is determined by the external SMBus host. All power supplies must have reached the operating levels mandated in Chapter 8.0, DC Parameters, prior to (or coincident with) the assertion of RESET_N. USB BUS RESET In response to the upstream port signaling a reset to the hub, the hub does the following: 1. 2. 3. 4. 5. 6. Sets default bus address to `0'. Sets configuration to: Unconfigured. Negates PRTPWR[4:1] to all downstream ports. Clears all TT buffers. Moves device from suspended to active (if suspended). Complies with Section 11.10 of the USB 2.0 Specification for behavior after completion of the reset sequence. The host then configures the hub and the hub's downstream port devices in accordance with the USB Specification. Note: The hub does not propagate the upstream USB reset to downstream devices.
