M29W320ET90N6T データシート - STMicroelectronics

SUMMARY DESCRIPTION
   The M29W320E is a 32 Mbit (4Mb x8 or 2Mb x16) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (2.7 to 3.6V) supply. On power-up the memory defaults to its Read mode.
