Supports external charge pump or external V
Complete control over USB termination resistors
Data line and V
Integrated V
Integrated cable (ID) detector
3.0 V to 4.5 V supply voltage input range
Internal voltage regulator supplies 2.7 V or 3.3 V and 1.8 V
Supports interfacing I/O voltage of 3.0 V to 3.6 V; separate I/O voltage supply pins
minimize crosstalk
Power down internal regulators in Power-down mode when V
or when the chip is not selected
Typical operating current of 13 mA to 32 mA, depending on the USB speed and
bus utilization
Typical current consumption I
Power-down mode
3-state ULPI interface by the CHIP_SEL or CHIP_SEL_N pin, allowing bus reuse
by other applications
60 MHz, 8-pin or 12-pin interface between the core and the transceiver, including a
4-bit DDR bus or an 8-bit SDR bus
DDR or SDR interface selectable by pin
Supports 60 MHz output clock configuration
Integrated Phase-Locked Loop (PLL) supporting input clock frequencies of
13 MHz, 19.2 MHz, 24 MHz or 26 MHz
Crystal or clock frequency selectable by pin
Fully programmable ULPI-compliant register set
3-pin or 6-pin full-speed or low-speed serial mode
Internal Power-On Reset (POR) circuit
Supports transparent UART signaling on DP and DM pins for the UART accessory
application
2.7 V UART signaling on DP and DM pins
Entering UART mode by register setting
Exiting UART mode by asserting STP or by toggling the CHIP_SEL or
CHIP_SEL_N pin
