DESCRIPTION

The Microchip Technology Inc. 24AA32 is a 4K x 8

(32K bit) Serial Electrically Erasable PROM capable of

operation across a broad voltage range (1.8V to 6.0V).

This device has been developed for advanced, low

power applications such as personal communications

or data acquisition. The 24AA32 features an input

cache for fast write loads with a capacity of eight 8-byte

pages, or 64 bytes. It also features a fixed 4K bit block

of ultra-high endurance memory for data that changes

frequently. The 24AA32 is capable of both random and

sequential reads up to the 32K boundary. Functional

address lines allow up to eight 24AA32 devices on the

same bus, for up to 256K bits address space.
