The AT29C256-70JI from Atmel is a 256K bit in-system Flash programmable and erasable read-only memory (PEROM). Organized as 32,768 words by 8 bits, this device operates on a single 5V supply with a ±10% tolerance.
Key electrical characteristics include a fast read access time of 70 ns, a typical active current of 50 mA, and a low CMOS standby current of 300 µA. The device supports page program operations with a typical program time of 10 ms for a 64-byte page and a chip erase time of 10 ms. It offers typical endurance exceeding 10,000 cycles.
Manufactured using Atmel's advanced nonvolatile CMOS technology, the AT29C256-70JI provides hardware and software data protection. It is compatible with CMOS and TTL inputs and outputs. The device is available in a PLCC package and is suitable for commercial and industrial temperature ranges.
Reprogramming is performed on a page basis, where 64 bytes are latched internally, freeing the address and data bus. The end of a program cycle can be detected using DATA polling.
