*NOTICE:

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Pin Description

SERIAL CLOCK SCL The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device.

SERIAL DATA SDA The SDA pin is bidirectional for serial data transfer. This pin is open-drain driven and may be wire-ORed with any number of other open-drain or open collector devices.

DEVICE/PAGE ADDRESSES A2, A1, A0 The A2, A1 and A0 pins are device address inputs that are hard wired or left not connected for hardware compatibility with AT24C16. When the pins are hardwired, as many as eight 32K/64K devices may be addressed on a single bus system device addressing is discussed in detail under the

Device Addressing section . When the pins are not hardwired, the default A2, A1, and A0 are zero. WRITE PROTECT WP The write protect input, when tied to GND, allows normal write operations. When WP is tied high to VCC, all write operations to the upper quandrant 8/16K bits of memory are inhibited. If left unconnected, WP is internally pulled down to GND.

Memory Organization

AT24C32/64, 32K/64K SERIAL EEPROM The 32K/64K is internally organized as 256 pages of 32 bytes each. Random word addressing requires a 12/13 bit data word address.
