The AM29F040B-120PC is a 4-Megabit, 5.0 Volt-only Flash memory device organized as 512K x 8 bits. It is manufactured by Advanced Micro Devices (AMD). 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 device offers a good balance of capacity and performance for a range of embedded applications. Its reliable operation and relatively fast access times contribute to its suitability for various systems.

Additional Details

The AM29F040B-120PC includes features such as sector protection, which prevents accidental program or erase operations in designated memory regions. The device also supports program and erase suspend/resume, allowing interruption of program or erase cycles for system-level tasks. It offers a minimum of 10,000 write/erase cycles. Sector erase time is typically around 0.7 seconds, and byte programming time is typically 10µs.
