The PC28F256G18FE is a 256MB StrataFlash Embedded Memory featuring flexible, multiple-partition, dual-operation architecture. The device provides high-performance, asynchronous read mode and synchronous-burst read mode using 1.8V low-voltage, multilevel cell (MLC) technology. The multiple-partition architecture enables background programming or erasing to occur in one partition while code execution or data reads take place in another partition. This dual-operation architecture also allows two processors to interleave code operations while PROGRAM and ERASE operations take place in the background. The multiple partitions allow flexibility for system designers to choose the size of the code and data segments. This device provides high read and write performance at low voltage on a 16-bit data bus. The multi-partition architecture provides read-while-write and read-while-erase capability, with individually erasable memory blocks sized for optimum code and data storage.
