DESCRIPTION
The Microchip Technology Inc. 24FC32 is a 4K x 8 (32K
bit) Serial Electrically Erasable PROM (EEPROM) with
a high-speed 1 MHz SE2.bus whose protocol is
functionally equivalent to the industry-standard I
This device has been developed for advanced, low
power applications such as personal communications
or data acquisition. The 24FC32 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 24FC32 is capable of both random and
sequential reads up to the 32K boundary. Functional
address lines allow up to 8 - 24FC32 devices on the
same bus, for up to 256K bits address space. The
24FC32 is available in the standard 8-pin plastic DIP
and 8-pin surface mount SOIC package.
