The AT28HC64B-12SI from Microchip Technology is a high-performance, 64Kbit electrically erasable and programmable read-only memory (EEPROM). It is organized as 8,192 words by 8 bits and manufactured using advanced nonvolatile CMOS technology.
This device offers fast read access times, with specifications varying between 55 ns and 120 ns depending on the source. It operates from a single 5V ±10% supply voltage (4.5V to 5.5V range) and consumes low power, with an active current of 40 mA and a CMOS standby current of less than 100 µA. The write cycle time is specified as 10 ms maximum for page writes.
Designed for reliability, the AT28HC64B-12SI boasts an endurance of 100,000 cycles and data retention for 10 years. It supports hardware and software data protection features, including DATA polling for end-of-write detection. The device is compatible with CMOS and TTL inputs and outputs and adheres to the JEDEC approved byte-wide pinout.
Packaged in a 28-SOIC surface mount package, this EEPROM is suitable for industrial temperature ranges from -40°C to 85°C. It also offers a green (Pb/Halide-free) packaging option.
