The AT28C040-20FI is a high-performance, 4-megabit electrically erasable and programmable read-only memory (EEPROM) from Microchip Technology. Organized as 524,288 words by 8 bits, this device offers fast access times of 200 ns.
Manufactured using advanced nonvolatile CMOS technology, the AT28C040-20FI operates from a single 5V ± 10% supply, consuming low power with a typical active current of 50 mA. It supports automatic page write operations, latching up to 256 bytes simultaneously for efficient writing. The end of a write cycle can be detected using DATA Polling.
This EEPROM features hardware and software data protection mechanisms, high reliability with an endurance of 10,000 cycles, and data retention of 10 years. It is compatible with CMOS and TTL logic levels and features a JEDEC approved byte-wide pinout.
The device is supplied in a 32-FlatPack, Ceramic Bottom-Brazed package suitable for surface mounting. Its operating temperature range is -40°C to 85°C (TC).
