... CC V Ground SS SUMMARY DESCRIPTION The M29F040B Mbit (512Kb x8) non-volatile memory that can be read, erased and repro- grammed. These operations can be performed us- ing a single 5V supply. On power-up the memory defaults to its Read mode where it can be read in the same way as a ROM or EPROM. The M29F040B is fully backward compatible with the M29F040 ...
