M89 In-System Programmable ISP Multiple-Memory and Logic

The FLASH+PSD family of memory systems for microcontrollers (MCUs) brings In-SystemProgrammability (ISP) to Flash memory and programmable logic. The result is a simple and flexible solution for embedded designs. FLASH+PSD devices combine many of the peripheral functions found in MCU based applicatio.
