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.

M29W320E has an extra 32 Kword (x16 mode) or 64 Kbyte (x8 mode) block, the Extended Block, that can be accessed using a dedicated command. The Extended Block can be protected and so is useful for storing security information. However the protection is irreversible, once protected the protection cannot be undone.
