Product Summary
The PC28F640P30B is a numonyx strata flash embedded memory. The PC28F640P30B provides density upgrades from 64-Mbit through 512-Mbit. This PC28F640P30B 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 PC28F640P30B defaults to asynchronous pagemode read. Configuring the Read Configuration Register enables synchronous burstmode reads. In synchronous burst mode, output data is synchronized with a usersupplied clock signal. A WAIT signal of the PC28F640P30B provides an easy CPU-to-flash memory synchronization.
