Description

The M29W800D is a 8-Mbit (1 Mbit x 8 or 512 Kbits x 16) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6 V) 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.
