DESCRIPTION
The Microchip Technology Inc. 24C32A is a 4K x 8 (32K
bit) Serial Electrically Erasable PROM. It has been
developed for advanced, low power applications such
as personal communications or data acquisition. The
24C32A also has a page-write capability of up to 32
bytes of data. The 24C32A is capable of both random
and sequential reads up to the 32K boundary. Func-
tional address lines allow up to eight 24C32A devices
on the same bus, for up to 256K bits address space.
Advanced CMOS technology and broad voltage range
make this device ideal for low-power/low-voltage, non-
volatile code and data applications. The 24C32A is
available in the standard 8-pin plastic DIP and both 150
mil and 200 mil SOIC packaging.
- Commercial (C): 0˚C to 70˚C
- Industrial (I): -40˚C to +85˚C
- Automotive (E): -40˚C to +125˚C
