SDA

I/O

500kΩ internal pulled high and 1.8MΩ internal pulled down.

In I2C mode:

Bidirectional I2C data pin; Connected to a pull-up resistor

During power up, pulled up SDA and SCL/CD with Rpu (<10kΩ) to enter I2C mode OR

floating to enter Pin mode

In Pin mode: Do not connect

4

SCL/CD

I/O

In I2C mode: I2C Clock pin

During power up, pulled up SDA and SCL/CD with Rpu (<10kΩ) to enter I2C mode OR

floating to enter Pin mode (500kΩ pull-down during RSTN rising)

In Pin mode:

Output CD, Flag indicating that a USB device is attached. Asserted from an unconnected

state upon detection of DP or DM pull up resistor. De-asserted upon detection of discon-

nect.

5

RSTN

I

Device disable/enable.

Low – Device is at RESET and in shutdown, and

High – Normal operation.

500kΩ internal pulled high and 1.8MΩ internal pulled down.

Recommend 0.1-uF external capacitor to GND to ensure clean power on reset if not driven.

If the pin is driven, it must be held low until the supply voltage for the device reaches

within specifications.

6

BOOST

I

USB High Speed Boost selection.

Select via external pull down resistor.

Sampled upon de-assertion of RSTN. Does not recognize real time adjustments.
