M29W320ET General 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.
The device features an asymmetrical block architecture. The M29W320E has an array of 8 parameter and 63 main blocks. M29W320ET locates the Parameter Blocks at the top of the memory address space while the M29W320EB locates the Parameter Blocks starting from the bottom.
