Vue d'ensemble

Description

The AM29F040B-90JF is a 4Mbit (512KB x 8) Flash memory device produced by AMD. It is designed for applications requiring non-volatile storage, allowing for data retention without power. The device operates with a supply voltage of 3V to 3.6V and features a fast access time of 90ns, making it suitable for high-performance applications.
The AM29F040B utilizes a 32-pin DIP or TSOP package and supports both byte and word access. It features programmable and erasable capabilities, allowing users to write or erase data at the byte level. The device supports standard command sets for reading, writing, and erasing, ensuring compatibility with various microcontrollers.
With its endurance of up to 1,000,000 write/erase cycles and a data retention of up to 20 years, the AM29F040B is reliable for embedded systems, consumer electronics, and telecommunications applications. Its architecture allows for concurrent read and write operations, improving overall system performance.

Package

The AM29F040B-90JF is packaged in a 32-pin PLCC (Plastic Leaded Chip Carrier) format.

Pinout

The AM29F040B-90JF is a 4 Megabit (512 K x 8) flash memory chip with a pin count of 32. It is part of the Am29F040 family of devices, featuring a dual 8-bit data bus.
