It supports the 8-bit wide SDR data path. The primary IOs of this block support multi-range LVCMOS signaling from 1.8V to 3.3V (±5%). The level used is automatically selected by the voltage applied to Vccio and is set at any voltage between 1.8V and 3.3V. Oscillator (OSC) This block meets the requirements of both the on-chip PLL and the USB-IF requirements for clock parameters. It is a fundamental mode parallel resonant oscillator with a maximum ESR of 60 ohms. It supports the following: ■ Tri-state the ULPI bus output pins ■ Associate with RESET_N to place TX2UL in the Sleep mode When the CS_N pin is deasserted (high), all the pins in the ULPI interface are tri-stated. USB2 Transceiver Macrocell Interface (UTMI+) This block conforms to the UTMI+ Level 0 standard. It performs all the UTMI to USB translation. Global Control This block is the digital control logic that ties the blocks of the device together. Functions performed include pull up control, over current protect control, and more. ■ Integrated Crystal Oscillator - 13, 19.2, 24, or 26 MHz crystal Full Speed and High Speed USB Transceivers (FS/HS) ■ 13, 19.2, 24, or 26 MHz LVCMOS single ended input clock on XI The FS and HS Transceivers comply fully with the USB 2.0 specifications. Phase Locked Loop (PLL) The PLL meets all clock stability requirements imposed by this device and the USB standard. It supports all requirements to make the device compliant to the USB 2.0 specifications. It also has a fractional multiplier that enables it to supply the correct frequency to the device when it is presented with a 13, 19.2, 24, or 26 MHz reference clock. Power On Reset (POR) This block provides a power on reset signal (internal) based on the input supply. An internal power on reset is generated when VCC input rises above VPOR(trip). Reset (RESET_N) The three major functions of RESET_N pin are as follows: ■ Reset TX2UL ■ Place TX2UL into Sleep Mode ■ Place TX2UL into Configuration Mode When the RESET_N pin is asserted (low) for tSTATE (tSTATE is specified in Table 21 on page 19), the TX2UL enters into either Sleep Mode or Configuration Mode depending on the CS_N state. When RESET_N is asserted while CS_N is asserted, TX2UL enters into Sleep Mode. When RESET_N is asserted for tSTATE while CS_N is deasserted, TX2UL enters into Configuration Mode. In these modes, all the pins in the ULPI interface are tri-stated. If the RESET_N pin is not used, it must be pulled high. For more information about different modes of configuration, see Table 5 on page 4. DP and DM pins The DP and DM pins are the differential pins for the USB. They must be connected to the corresponding DP and DM pins of the USB receptacle. Chip Select (CS_N) This signal pin is available only in 24-pin QFN package. The two major functions of CS_N are as follows: USB Pull up and Intr Detect, Termination Resistors (Pull up / TERM) These blocks contain the USB pull up and termination resistors as specified by the USB 2.0 specification. UART Pass Through Mode TX2UL supports Carkit UART Pass Through Mode. When the Carkit Mode bit in the Interface Control register is set, it enables the Link to communicate through the DP/DM to a remote system using UART signaling. By default, the clock is powered down when the TX2UL enters Carkit Mode. Entering and exiting the Carkit Mode is identical to the Serial Mode. Table 1, Table 2, and Figure 1 show the UART Signal Mapping between the DP/DM and DATA[1:0] at ULPI interface. Table 1.

The internal PLL applies the proper clock multiply option depending on the input frequency. For applications that use an external clock source to drive XI, the XO pin (in 24-pin QFN package) is left floating. TX2UL has an on-chip oscillator circuit that uses an external 13, 19.2, 24, or 26 MHz (±100 ppm) crystal with the following characteristics: ■ ■ Parallel Resonant Fundamental Mode ■ 750 mW Drive Level The selection between input clock source and frequency on the XI pin is determined by the Chip Configuration register loaded through the RESET_N during Configuration Mode. The external clock source requirements are shown in Figure 3 on page 4. Figure 2.

It can range anywhere from 3.0 to 5.775V during actual operation. ■ VCC ■ VIO ■ VBATT TX2UL has two grounds: ■ VSS ■ VSSBATT Voltage Regulator The internal 3.3V regulator block regulates the VBATT supply to the internal 3.3V supply for the USBIO and XOSC blocks. If the supply voltage at VBATT is below 3.3V, the regulator block switches the VBATT supply directly for the USBIO and XOSC blocks. VCC Power Supply Sequence This is the core 1.8V power supply for the TX2UL. It can range anywhere from 1.7V to 1.9V during actual operation. TX2UL does not require power supply sequence. All power supplies are independently sequenced without damaging the part. All supplies are up and stable for the device to function properly. The analog block contains circuitry that senses the power supply to determine when all supplies are valid. VIO This is the 1.8V to 3.3V multi range supply to the I/O ring. It can range anywhere from 1.7V to 3.6V during actual operation. Page 3 of 5 CY7C68003 Operation Modes There are six operation modes available in TX2UL. They are: ■ Normal Operation Mode ■ Configuration Mode ■ ULPI Low Power Mode ■ Sleep Mode ■ Carkit UART Pass Through Mode ■ Tri-state ULPI Interface Output Mode (only available in 24-pin QFN package) When changing the operation modes, if the current and changing modes are not the Normal Operation Mode, TX2UL first changes to the Normal Operation Mode. For example, to change from ULPI Low power mode to Sleep mode, TX2UL changes to Normal operation mode first, and then changes to Sleep mode. The Mode Change State diagram in Figure 3 shows the mode change path of TX2UL. The entries of the six operations modes (20-pin CSP package has 5 operation modes) are listed in Table 4 and Table 5. There are three mode change transactions that require the RESET_N assert or deassert with tSTATE (see Table 21 on page 19 for tSTATE). These three mode change transactions are: ■ Change from Normal Operation Mode to Configuration Mode – RESET_N is required to assert with tSTATE ■ Change from Configuration Mode to Normal Operation Mode – RESET_N is required to de-assert with tSTATE ■ Change from Normal Operation Mode to Sleep Mode – RESET_N is required to assert with tSTATE Figure 3.

Enter into ULPI Low Power Mode by setting SuspendM register bit (in Function Control Register) to 0 during the Normal Operation Mode. 0 (Low) 1 (High) Enter into Carkit UART Pass Through Mode by setting Carkit Mode register bit (in Interface Control Register) to 1 during the Normal Operation Mode. 1 (High) 0 (Low) Configuration Mode 1 (High) 1 (High) Tri-state ULPI Interface output pins 0 (Low) Enter into Configuration Mode when Power On (VCC On) Page 4 of 5 CY7C68003 The operation and configuration modes are described in Operation Modes on page 4 and Configuration Mode on page 14 respectively. The ULPI Low power mode and Sleep mode are described in the following sections: ULPI Low Power Mode In this mode, the link optionally places the TX2UL in low power mode when the USB is suspended. TX2UL powers down all the circuitry except for the interface pins and full speed receiver. To enter low power mode, the link must set SuspendM in the Function Control register to 0b. The TX2UL clock is stopped for a minimum of five cycles after TX2UL accepts the register write. To exit the low power mode, the link signals TX2UL to exit the mode by asynchronously asserting a signal, STP. The TX2UL wakes up its internal circuitry and when it meets the ULPI timing requirements it deasserts DIR. The SuspendM register is set to 1b. Sleep Mode Sleep mode is entered by asserting RESET_N during the Normal Operation Mode. When RESET_N is driven low for tSTATE (see Table 21 on page 19 for tSTATE requirement) while CS_N is low, TX2UL enters into Sleep Mode. VCC must remain supplied (ON) during the sleep mode. This mode powers down all internal circuitry except the RESET_N pin and the chip_config register. The ULPI interface bus is tri-stated. During the Sleep Mode ensure that: ■ The ULPI interface IOs is either floating or driven high by the link ■ DP and DM are either floating or pull to 0V ■ Deassert RESET_N to exit the Sleep Mode.
