usb 2.0 high-speed 3-port hub controller datasheet smsc usb2513 9 revision 1.98 (11-19-07) datasheet chapter 3 pin descriptions 3.1 pin descriptions this section provides a detailed description of each signal. the signals are arranged in functional groups according to their associated interface. the ?n? symbol in the signal name indicates that th e active, or asserted, state occurs when the signal is at a low voltage level. when ?n? is not presen t before 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 asser t, 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. table 3.1 usb2514 pin descriptions symbol 36 qfn 48 qfn buffer type description upstream usb interfaces usbup_dp usbup_dm 31 30 43 42 io-u usb bus data these pins connect to the upstream usb bus data signals (host port, or upstream hub). vbus_det 27 35 i/o12 detect upstream vbus power detects state of upstream vbus power. the smsc 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 power pin of the usb port that is upstream of the hub. for self-powered applications with a permanently attached host, this pin must be connected to 3.3v (typically vdd33). downstream 3-port usb 2.0 interface usbdn_dp[3:1]/ prt_dis_p[3:1] & usbdn_dm[3:1]/ prt_dis_m[3:1] 7 4 2 7 4 2 io-u high-speed usb data & port disable strap option these pins connect to the downstream usb peripheral devices attached to the hub?s port. 6 3 1 6 3 1 downstream port disable strap option: if this strap is enabled by package and configuration settings (see ta b l e 3 . 2 ), this pin will be sampled at reset_n negation to determine if the port is disabled. both usb data pins for the corresponding port must be tied to the vdda33 to disable the associated downstream port. prtpwr[3:1] 18 16 12 21 19 15 o12 usb power enable enables power to usb peripheral devices downstream. the active signal level of the prtpwr[3:1] pins is determined by the power polarity strapping function of the prtpwr_pol pin.

usb 2.0 high-speed 3-port hub controller datasheet revision 1.98 (11-19-07) 34 smsc usb2513 datasheet 4.4 smbus slave interface instead of loading user-defined descriptor data from an external eeprom, the smsc 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 in terface; if cfg_sel1 & cfg_sel0 activates the smbus interface, external eeprom support is no lo nger available (and the user-defined descriptor data must be downloaded via the smbu s). due to system issues, the sm sc 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 complete. the hub?s smbus implementation is a subset of t he smbus interface to the host. the device is a slave-only smbus device. the implementation in the device is a subset of smbus since it only supports two protocols. the write block and read block protocols are the only valid smbus protocols for the hub. the hub responds to other protocols as described in section 4.4.2, "invalid protocol response behavior," on page 35 . reference the system managemen t bus specification, rev 1.0. the smbus interface is used to read and write the re gisters in the device. the register set is shown in section 4.3.1, "internal re gister set (common to eeprom and smbus)," on page 19 . 4.4.1 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 add ress field, and an 8-bit data field. the shading indicates the hub driving data on the smbdata li ne; otherwise, host data is on the sda/smbdata line. the slave address is the unique smbus interface addre ss 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 r egister or the contents of the register that the host is attempting to read. note: data bytes are transferred msb first (msb first). 4.4.1.1 block read/write the block write begins with a slave address and a wr ite condition. after th e 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: figure 4.1 block write denotes master-to-slave denotes slave-to-master 1 81 s slave address register address wr a 17118 a 1 ... byte count = n a data byte 1 a data byte 2 81 1 1 88 data byte n a p block write a
usb 2.0 high-speed 3-port hub controller datasheet smsc usb2513 35 revision 1.98 (11-19-07) datasheet 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 ch ange in the transfer direction. figure 4.2 block read 4.4.2 invalid protocol response behavior registers that are accessed with an invalid prot ocol 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. attempting to communicate with the hub over smbu s 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 t he smbus slave address are the registers defined in the registers section. see section 4.4.3 for the response to undefined registers. 4.4.3 general call address response the hub does not respond to a general call address of 0000_000b. 4.4.4 slave device time-out according to the smbus specificat ion, v1.0 devices in a transfer can abort the transfer in progress and release the bus when any single clock low interval exceeds 25ms (t timeout, min ). devices that have detected this condition must reset their communication and be able to receive a new start condition no later than 35ms (t timeout, max ). note: 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. 4.4.5 stretching the sclk signal the hub supports stretching of the sclk by othe r devices on the smbus. the hub does not stretch the sclk. 4.4.6 smbus timing the smbus slave interface complie s with the smbus ac timing specification. see the smbus timing in the ?timing diagram? section. block read 1 s s slave address register address wr a 17118 a 1 slave address rd a 711 81 1 1 88 p 1 81 a a a a byte count = n data byte 1 data byte 2 data byte n ...

(please see section 4.3.1, "internal register set (c ommon to eeprom and smbus)" for specific details on how to enable default configuration.) please refer to ta b l e 4 . 2 for the internal default values that are loaded when this option is selected. 4.6 default strapping options: the usb2514 can be configured via a combination of internal default values and pin strap options. please see ta b l e 3 . 1 and ta b l e 3 . 2 for specific details on how to enable the default/pin-strap configuration option. the strapping option pins only cover a limited sub-set of the configuration options. the internal default values will be used for the bits & registers that ar e not controlled by a strapping option pin. please refer to table 4.2 for the internal default values that ar e loaded when this option is selected. the green led pins are sampled after reset_n negatio n, and the logic values are used to configure the hub if the internal default configuration mode is selected. the implem entation shown below (see figure 4.3 ) shows a recommended passive scheme. when a pin is configured with a ?strap high? configuration, the led functions wit h active low signalling, and the pad will ?sink? the current from the external supply. when a pin is configured with a ?strap low? configuration, the led functions with active high signalling, and the pad will ?sour ce? the current to the external led.
usb 2.0 high-speed 3-port hub controller datasheet smsc usb2513 37 revision 1.98 (11-19-07) datasheet figure 4.3 led strapping option 4.7 reset there are two different resets that the hub experiences. one is a hardware reset (either from the internal por reset circuit or via the reset_n pin) and the second is a usb bus reset. 4.7.1 internal por hardware reset all reset timing parameters are guaranteed by design. 4.7.2 external hardware reset_n a valid hardware reset is defined as assertion of reset_n for a minimum of 1us 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. all downstream ports are disabled, and prtpwr power to downstream devices is removed. 2. the phys are disabled, and the differential pairs will be in a high-impedance state. 3. all transactions immediately terminate; no states are saved. 4. all internal registers return to the default state (in most cases, 00(h)). 5. the external crystal oscillator is halted. 6. the pll is halted. 7. led indicators are disabled. the hub is ?operational? 500 s after reset_n is negated. once operational, the hub immediately reads oem-spe cific data from the external eeprom (if the smbus option is not disabled). hub 100k strap low led pin 100k strap high led pin +v led led
