Product data sheet
7.4 ID detector
7.5 Pull-up and pull-down resistors
7.6 Analog USB Transceiver (ATX)
7.7 3.3 V DC-DC regulator
7.8 Carkit interrupt detector
In either active or suspended power mode, the ID detector senses the condition of the ID
line and differentiates between the following three conditions:
The ID detector also has a switch that can be used to ground pin ID. This switch is
controlled by bit ID_PULLDOWN in the serial controller.
The pull-up and pull-down resistors include the following switchable resistors:
The pull-up resistor is a context variable as described in the ECN_27%_Resistor
document. The variable pull-up resistor hardware is implemented to meet the USB
ECN_27% specification.
The behavior of the USB transceiver depends on operation mode of the ISP1301:
The built-in 3.3 V DC-DC regulator conditions the supply voltage (V
ISP1301:
The output of the regulator can be monitored on the VREG3V3 pin.
The carkit interrupt detector is a comparator that detects when the DP line is below the
carkit interrupt threshold V
enabled in audio mode only (bit AUDIO_EN = 1).

Pin ID is floating; bit ID_FLOAT = 1
Pin ID is shorted to ground; bit ID_GND = 1
Pin ID is connected to ground through resistor R

In USB mode, the USB transceiver block performs USB full-speed or low-speed
transceiver functions. This includes differential driver, differential receiver and
single-ended receivers.
In transparent general purpose buffer mode or UART mode, USB transceiver block
functions as a level shifter between pins DAT/VP and SE0/VM and pins DP and DM.
