The AM29F040B-150JC is a 4-Megabit, 5.0 Volt-only Flash memory device manufactured by Advanced Micro Devices (AMD). It is organized as 512K words of 8 bits each. The device is offered in a 32-pin PLCC package. The AM29F040B is designed to be programmed in-system with the standard system 5.0 volt VCC supply. A 12.0 volt VPP is not required for program or erase operations. The device can also be programmed in standard EPROM programmers.

This Flash memory device offers a combination of speed, capacity, and reliability for various embedded applications. Its sector erase architecture enhances flexibility and allows for efficient data management.
