The W72M64V-XBX 2M x 64bit Flash memory, housed in a 159 PBGA package, allows simultaneous read/write operation with zero latency between changes in operation. It offers low power consumption, a 70% reduction in board space, 21% saving in I/O connections and a significant decrease in parasitic capacitance over discrete solutions. An unlock bypass program reduces overall programming time while built-in sector protection measures ensure data integrity.

The W72M64V-XBX's low-power operation means that it consumes a maximum of 180mA in active mode and 20mA in standby mode making it ideal for use in data storage and/or operating code storage.

When addresses have been stable for a specified amount of time, the device enters the automatic sleep mode.

The system can also switch the device into standby mode.

Power consumption is greatly reduced in both modes.

Individual chip select and write enable functions allow the user to configure the device to 4M x 32 or 8M x 16bit.

The device's built-in data protection measures include a low Vcc detector that automatically inhibits write operations during power transitions.

The hardware sector protection feature disables both program and erase operations in any combination of the sectors memory.

This can be achieved in-system or via programming equipment.

The 2M x 64bit Flash has access times of 100, 120 and 150ns and requires only a single 3.3V power supply for both read and write functions making it ideal for high-end high-reliability embedded applications that require a 64bit wide solution.

Sector architecture consists of a two-bank structure with 8 x 4Kword and 15 x 32Kword sectors in bank one and 48 x 32Kword sectors in bank two.
