AT24C11 [Preliminary]
3409B–SEEPR–12/03
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
AT24C11, 1K SERIAL EEPROM:
Internally organized with 128 pages of 1 byte each.
The 1K requires a 7-bit data word address for random word addressing.
