Description
The Microchip Technology Inc. 24XX01
(1)
is a 1 Kbit
Electrically Erasable PROM. 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.

† NOTICE:
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operational listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
