PIN Function Table
PIN DESCRIPTIONS
A0, A1, A2 Chip Address Inputs
The A0...A2 inputs are used by the 24C32 for multiple device operation and conform to the two-wire
bus standard. The levels applied to these pins define the address block occupied by the device in the
address map. A particular device is selected by transmitting the corresponding bits (A2, A1, and A0) in
the control byte.
SDA Serial Address/Data Input/Output
This is a bidirectional pin used to transfer addresses and data into and data out of the device. It is an
open drain terminal; therefore the SDA bus requires a pull-up resistor to VCC (typical 10KQ for 100
kHz, 1KQ for 400 kHz).
