The STMicroelectronics M29F040B-90K1 is a 4 Mbit (512Kb x8) non-volatile memory that can be read, erased, and reprogrammed using a single 5V supply. On power-up, it defaults to Read mode, functioning similarly to a ROM or EPROM.
This memory is divided into 8 uniform 64 Kbyte blocks, allowing for independent erasure. Each block can also be independently protected to prevent accidental modification. Key electrical specifications include an access time of 45ns and a typical programming time of 8 μs per byte. It operates with a single 5V ±10% supply voltage for all operations.
The M29F040B-90K1 is offered in a 32PLCC package. It boasts 100,000 program/erase cycles per block and 20 years of data retention. The device includes an embedded program/erase controller and supports erase suspend and resume modes for flexible operation.
