Description
The Microchip Technology Inc. 24XX256
(1)
is a 32K x 8
(256 Kbit) Serial Electrically Erasable PROM, capable
of operation across a broad voltage range (1.7V to
5.5V). It has been developed for advanced, low-power
applications such as personal communications or data
acquisition. This device also has a page write capability
of up to 64 bytes of data. This device is capable of both
random and sequential reads up to the 256K boundary.
Functional address lines allow up to eight devices on
the same bus, for up to 2 Mbit address space.
