Description
The Microchip Technology Inc. 24XX04
(1)
is a 4-Kbit
Electrically Erasable PROM (EEPROM). The device is
organized as two blocks of 256 x 8-bit memory with a
two-wire serial interface. Its low-voltage design permits
operation down to 1.7V with standby and active
currents of only 1 µA and 1 mA, respectively. The
24XX04 also has a page write capability for up to
16 bytes of data.
Note 1:
24XX04 is used in this document as a
generic
part
number
for
the
24AA04/24LC04B/24FC04 devices.

Characterized but not 100% tested.
As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region
(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.
