Description

The Microchip Technology Inc. 24AA32A is a 4K x 8 (32K bit) Serial Electrically Erasable PROM capable of operation across a broad voltage range (1.8V to 6.0V). It has been developed for advanced, low power applica-tions such as personal communications or data acqui-sition. The 24AA32A also has a page-write capability of up to 32 bytes of data. The 24AA32A is capable of both random and sequential reads up to the 32K boundary.

Functional address lines allow up to eight 24AA32A 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,nonvolatile code and data applications. The 24AA32A is available in the standard 8-pin plastic DIP and both 150 mil and 200 mil SOIC packages.
