DS21126E-page 1 24FC32 Features • Voltage operating range: 4.5V to 5.5V - Maximum write current 3 mA at 5.5V - Maximum read current 150 µA at 5.5V - Standby current 1 µA typical • 1 MHz SE2.bus two wire protocol • Self-timed write cycle (including auto-erase) • Power on/off data protection circuitry • Endurance: - 10,000,000 Erase/Write cycles ensured for a 4K block - 1,000,000 E/W cycles ensured for a 28K block • 8-byte page, or byte modes available • 1 page x 8 line input cache (64 bytes) for fast write loads • Schmitt Trigger inputs for noise suppression • 2 ms typical write cycle time, byte or page • Up to 8 chips may be connected to the same bus for up to 256K bits total memory • Electrostatic discharge protection > 4000V • Data retention > 200 years • 8-pin PDIP/SOIC packages • Temperature ranges 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 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.
