11.4. Pinning
12. 32K Smart Serial EEPROM – 24C32
12.1. General Description
The Microchip Technology Inc. 24C32 is a 4K x 8 (32K bit) Serial Electrically Erasable
PROM. This device has been developed for advanced, low power applications such as
personal communications or data acquisition. The 24C32 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
24C32 is capable of both random and sequential reads up to the 32K boundary.
Functional address lines allow up to eight 24C32 devices on the same bus, for up to
256K bits address space. Advanced CMOS technology makes this device ideal for low-
power non-volatile code and data applications. The 24C32 is available in the standard 8-
pin plastic DIP and 8-pin surface mount SOIC package.
