Pin Descriptions

Supply Voltage (VCC)

The VCC input is a 4.5V-to-5.5V positive voltage.

Serial Clock (CLK)

The CLK input is used to positive edge clock data into the device and negative edge

clock data out of the device. There is an internal pull-down on CLK.

Serial Data (I/O)

I/O is bidirectional for serial data transfer to and from the device.

Reset (RST)

The RST input is used to reset the address counter. There is an internal pull-up on RST.

Program (PGM)

The PGM input is used to determine the state of I/O as an input or output. There is an

internal pull-down on PGM.

Fuse (FUS)

The FUS input is used during the personalization of the device. There is an internal pull-

down on FUS.
