AT29C256-90PC Description

Short technical summary and product information.

The AT29C256-90PC is a 256Kbit in-system, 5-volt-only Flash programmable and erasable read-only memory (PEROM) from Microchip Technology. Organized as 32,768 words by 8 bits, this device utilizes advanced nonvolatile CMOS technology to provide fast access times of up to 70 ns. It operates on a single 5V ±10% supply and is compatible with both CMOS and TTL logic levels.

 

Designed for in-system reprogrammability without requiring high input voltages, the AT29C256-90PC features page program operation where 64 bytes are latched internally for simultaneous programming. The end of a program cycle can be detected using DATA polling. Key electrical characteristics include a typical active current of 50 mA and a low CMOS standby current of less than 300 µA. The device offers typical endurance exceeding 10,000 cycles.

 

This component is housed in a 28-DIP (0.600", 15.24mm) through-hole package, making it suitable for various embedded systems and microcontroller-based applications. The operating temperature range is 0°C to 70°C (TC).
