AT29C256-90JC Description

Short technical summary and product information.

The AT29C256-90JC from Microchip Technology is a 256Kbit in-system, Flash-programmable and erasable read-only memory (PEROM). Organized as 32,768 words by 8 bits, this non-volatile memory utilizes advanced CMOS technology for efficient operation.

 

Key electrical specifications include a fast read access time of 90 ns and a typical active current of 50 mA. Programming is handled on a page basis, with a page program time of 10 ms for 64 bytes and a chip erase time of 10 ms. The device operates from a single 4.5V to 5.5V supply and features low-power dissipation with a CMOS standby current of 300 µA.

 

This memory component is designed for in-system reprogrammability without requiring high input voltages. It supports hardware and software data protection. The device is housed in a 32-PLCC (J-Lead) package suitable for surface mounting and operates within a temperature range of 0°C to 70°C (TC).

 

With a typical endurance exceeding 10,000 cycles, the AT29C256-90JC is suitable for applications requiring frequent data updates and reliable non-volatile storage.
