I/O

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

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.
