A2 HV GENERATOR 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 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 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.
