SUMMARY DESCRIPTION

The M29W641D is a 64 Mbit (4Mb x16) non-volatile memory that can be read, erased and reprogrammed. These operations can be performed using a single, low voltage, 2.7V to 3.6V VCC supply for the circuitry and a 1.8V to 3.6V VCCQ supply for the Input/Output pins. An optional 12 V VPP power supply is provided to speed up customer programming.
