Description

The Microchip Technology Inc. 24AA32 is a 4K x 8 (32K bit) Serial Electrically Erasable PROM capable of oper-ation 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 fre- quently. The 24AA32 is capable of both random and sequential reads up to the 32K boundary. Functional address lines allow up to 8 - 24AA32 devices on the same bus, for up to 256K bits address space. dvanced CMOS technology and broad voltage range make this device ideal for low-power/low voltage, nonvolatile code and data applications. The 24AA32 is available in the standard 8-pin plastic DIP and 8-pin surface mount SOIC package.
