AT29C040A-90TI Description

Short technical summary and product information.

The AT29C040A-90TI is a 4-megabit, 5-volt only, in-system Flash Programmable and Erasable Read-Only Memory (PEROM) manufactured by Microchip Technology. Its memory is organized as 524,288 words by 8 bits, providing 4Mbit of storage capacity. This device offers a fast read access time of 90 ns, making it suitable for various applications requiring quick data retrieval.

 

The AT29C040A-90TI operates within a voltage range of 4.5V to 5.5V and features a low active current of 40 mA and a CMOS standby current of less than 100 µA. Programming is performed on a sector basis, with each sector containing 256 bytes. The device supports a sector program cycle time of 10 ms and utilizes DATA polling for end-of-program detection.

 

This Flash memory is available in a 32-TSOP package, designed for surface mounting. The operating temperature range is -40°C to 85°C (TC). Its non-volatile technology ensures data retention, and it is compatible with CMOS and TTL inputs and outputs.
