Description
The Microchip Technology Inc. 24XX16
(1)
is a 16-Kbit
Electrically Erasable PROM. The device is organized
as eight 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
24XX16 also has a page write capability for up to
16 bytes of data.
Note 1:
24XX16 is used in this document as a
generic
part
number
for
the
24AA16/24LC16B/24FC16 devices.
