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.

Memory Organization AT24C01ASC, 1K SERIAL EEPROM: Internally organized with 16 pages of 8 bytes

each, the 1K requires a 7-bit data word address for random word addressing.

AT24C02SC, 2K SERIAL EEPROM: Internally organized with 32 pages of 8 bytes

each, the 2K requires an 8-bit data word address for random word addressing.
