Block Diagram

*NOTICE:

Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam-

age 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 bi-directional 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.

AT24C04SC, 4K SERIAL EEPROM: The 4K is internally

organized with 32 pages of 16 bytes each. Random word

addressing Chip Number requires a 9-bit data word

address.

AT24C08SC, 8K SERIAL EEPROM: The 8K is internally

organized with 64 pages of 16 bytes each. Random word

addressing requires a 10-bit data word address.

AT24C16SC, 16K SERIAL EEPROM: The 16K is internally

organized with 128 pages of 16 bytes each. Random word

addressing requires an 11-bit data word address.
