Product Summary

The PC28F640P30B85 is a numonyx strata flash embedded memory. The PC28F640P30B85 provides density upgrades from 64-Mbit through 512-Mbit. The PC28F640P30B85 provides high performance at low voltage on a 16-bit data bus. Individually erasable memory blocks are sized for optimum code and data storage. Upon initial power up or return from reset, the PC28F640P30B85 defaults to asynchronous page mode read. Configuring the Read Configuration Register enables synchronous burst mode reads. In synchronous burst mode, output data is synchronized with a user supplied clock signal. A WAIT signal of the PC28F640P30B85 provides an easy CPU-to-flash memory synchronization.
