ULPI

The ULPI (ultra low pin count interface) is a low pin count USB PHY to a Link-Layer Controller interface. The ULPI consists of the interface and the ULPI registers. The TUSB1310A device is always the master of the ULPI bus.

Table 3-4 ULPI Signal Descriptions

SIGNAL NAME TYPE BALL NO. DESCRIPTION
ULPI_CLK O P11 60-MHz interface clock. All ULPI signals are synchronous to ULPI_CLK. The ULPI_CLK is always a 60-MHz output of the TUSB1310A device. In low-power mode, the ULPI_CLK is not driven.
ULPI_DATA7 S, I/O, PD N6 Data bus. Driven to 00h by the Link when the ULPI bus is idle.
8-bit data timed on rising edge of ULPI_CLK
ULPI_DATA6 P6
ULPI_DATA5 N7
ULPI_DATA4 P7
ULPI_DATA3 N8
ULPI_DATA2 P8
ULPI_DATA1 P9
ULPI_DATA0 N9
ULPI_DIR O M7 Controls the direction of the ULPI_DATA bus
0: ULPI_DATA lines are inputs
1: ULPI_DATA lines are outputs
ULPI_STP S, I, PU M8 Active High. The Link must assert ULPI_STP to signal the end of a USB transmit packet or a register write operation. The ULPI_STP signal must be asserted in the cycle after the last data byte is presented on the bus. The ULPI_STP has an internal weak pullup to safeguard against false commands on the ULPI_DATA lines.
ULPI_NXT O N11 Active High. The PHY asserts ULPI_NXT to throttle all data types, except register read data and the RX CMD. The PHY also asserts ULPI_NXT and ULPI_DIR simultaneously to indicate USB receive activity, if ULPI_DIR was previously low. The PHY is not allowed to assert ULPI_NXT during the first cycle of the TX CMD driven by the Link.

Clocking

Table 3-5 Clock Signal Name Descriptions

SIGNAL NAME TYPE BALL NO. DESCRIPTION
XI I A12 Crystal Input. This pin is the clock reference input for the TUSB1310A. The TUSB1310A device supports either a crystal unit, or a 1.8-V clock input. Frequencies supported are 20, 25, 30, or 40 MHz.
XO O A11 Crystal output. If a 1.8-V clock input is connected to XI, XO must be left open.
CLKOUT O D10 OOBCLK is driven in U3 mode.

JTAG Interface

The JTAG Interface is used for board-level boundary scan. All digital IO support IEEE1149.1 boundary scan and SuperSpeed differential pairs support IEEE1149.6 boundary scan.

Table 3-6 JTAG Signal Name Descriptions

SIGNAL NAME TYPE BALL NO. DESCRIPTION

Reset and Output Control Interface

Table 3-7 Reset and Output Control Signal Descriptions

SIGNAL NAME TYPE BALL NO. DESCRIPTION
RESETN I J11 Active Low. Resets the transmitter and receiver. This signal is asynchronous.
OUT_ENABLE I L10 Active High. This can be connected to a 1.8-V power-on-reset signal on the PCB to avoid static current and signal contention during power up.
0: Disable all driver outputs while I/O powers are supplied, but internal control circuit powers are not present during power up.
1: Enable all driver outputs during normal operation.

When in the isolate mode, the TUSB1310A device continues to respond to ULPI.
