The AT29C257-70JC is a 256Kbit (32K x 8) Flash memory device from Quarktwin Technology Ltd., designed for 5-volt-only operation. It features a fast read access time of 70 ns and supports single-cycle reprogramming with internal address and data latches for 64 bytes. The device allows for page programming with a program cycle time of 10 ms and a chip erase time of 10 ms. It incorporates both hardware and software data protection mechanisms to prevent inadvertent programming. The AT29C257 is characterized by low power dissipation, with an active current of 50 mA and a standby current of 300 ¬µA. It offers a typical endurance of over 10,000 cycles, making it suitable for applications requiring frequent data updates. The device is compatible with both CMOS and TTL logic levels and is pin-compatible with the AT29C010A and AT29C512, facilitating easy upgrades in existing systems. The operating temperature range for this commercial version is from 0¬8C to 70¬8C.
