Description
The Microchip Technology Inc. 24XX01
(1)
is a 1 Kbit
Electrically Erasable PROM (EEPROM). The device is
organized as one block of 128 x 8-bit memory with a
2-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
24XX01 also has a page write capability for up to
8 bytes of data.
Note 1:
24XX01 is used in this document as a
generic
part
number
for
the
24AA01/24LC01B/24FC01 devices.
