M28W640FSU General Description
The M28W320FSU and the M28W640FSU are 32 Mbit (2Mbit x 16) and 64 Mbit (4Mbit x 16) Secure Flash memories. The devices can be erased electrically at block level and programmed in-system on a Word-by-Word basis using a 2.7V to 3.6V VDD supply for the circuitry and a 2.7V to 3.6V VDDQ supply for the Input/Output pins. An optional 12V VPP power supply is provided to speed up customer programming.
The M28W320FSU and M28W640FSU feature 32 Mbits and 64 Mbits respectively and are divided into thirty-two and sixty-four 64-KWord Uniform blocks, respectively. Refer to Figure 5. for a detailed description of the devices memory architecture and map.
All devices are equipped with hardware and software block protection features to avoid unwanted program/erase (modify) or read of the Flash memory content:
