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 I2C
bus. 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
eight 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.
