AT28HC256-70JU

Microchip AT28HC256 is a high-performance 256Kbit parallel EEPROM, available in industrial and military temperature ranges, providing access times of up to 70ns and power dissipation of 440mW. When deselected, CMOS standby current is less than 5mA. Like static RAM, it can be read or written without external components and contains a 64-byte page register that can write up to 64 bytes simultaneously. Military models feature internal error correction circuitry for increased durability and data retention. Optional software data protection prevents accidental writes, and an additional 64-byte EEPROM enables device identification or tracking. Other Features: 32 Kbits x 8 (256 Kbit) 5V ± 10% Power Supply Parallel Interface 150ns Access Times Self-timed Erase and Write Cycles (10 ms max) Page Write and Byte Write End of Write Detection Data Round Inquire about low power consumption: Read/write current 40 mA (max) Standby current TTL 2 mA (max), CMOS 200 μA (max)
