• Manufacturer Part Number: is24c32c-2pli
• Description: 32k-bit 2-wire Serial Cmos Eeprom
• Manufacturer: Integrated Silicon Solution, Inc.

IS24C32C
PIN CONFIGURATION
8-Pin DIP, SOIC, TSSOP, and MSOP
PIN DESCRIPTIONS
SCL
This input clock pin is used to synchronize the data
transfer to and from the device.
SDA
The SDA is a Bi-directional pin used to transfer addresses
and data into and out of the device. The SDA pin is an open
drain output and can be wire-Ored with other open drain
or open collector outputs. The SDA bus requires a pullup
resistor to Vcc.
A0, A1, A2
The A0, A1 and A2 are the device address inputs that are
hardwired or left not connected for hardware compatibility
with the 24C16. When pins are hardwired, as many as eight
32K devices may be addressed on a single bus system.
When the pins are not hardwired, the default values of A0,
A1, and A2 are zero.
WP
WP is the Write Protect pin. The input level determines if all
or none of the array is protected from modifications.
