... M29W320ET, M29W320EB 1 Description The M29W320E 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 ...

... Signal descriptions 2.7 Write Enable (W) The Write Enable, W, controls the Bus Write operation of the memory’s Command interface. 2.8 V Write Protect (V PP/ The V /Write Protect pin provides two functions. The V PP use an external high voltage power supply to reduce the time required for Program operations ...

Page 15

... This prevents Bus Write operations from accidentally damaging the data LKO during power up, power down and power surges. If the Program/Erase Controller is programming or erasing during this time then the operation aborts and the memory contents being altered will be invalid. A 0.1µF capacitor should be connected between the V Ground pin to decouple the current surges from the power supply ...
