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. Advanced
CMOS technology and broad voltage range make this
device ideal for low-power/low voltage, nonvolatile code
