11.6. 24C32
11.6.1. 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 8 - 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.
11.6.2. Features
