The W72M64V-XBX 3.3V Flash memory from White Electronic Designs Corp. (WEDC) is packaged in a 13-by-12mm, 159 PBGA package, saving up to 70 percent of board space and reducing I/O connections by up to 21 percent, while providing reduced trace lengths for reduced parasitics.

Designed for data and/or operating code storage, the device consumes a maximum of 180mA in active mode and 20mA in standby mode. It allows simultaneous R/W operation with one bank continuously reading, while the other is executing erase or program functions.

The 2Mx64 chip has a select and write enable function, allowing the memory device to be configured as 4Mx32 or 8Mx16. It is also offered in commercial, industrial, and military temperature ranges. Access times are 100ns, 120ns, and 150ns.

Data protection features include a low voltage 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 of memory. This can be done via in-system or programming equipment.
