Introduction
The PSD8XX series of Programmable Microcontroller (MCU) Peripherals brings In-System-Programmability (ISP) to Flash memory and programmable logic. The result is a simple and flexible solution for embedded designs. PSD8XX devices combine many of the peripheral functions found in MCU based applications:
    • 4 Mbit of Flash memory
    • A secondary Flash memory for boot or data
    • Over 3,000 gates of Flash programmable logic
    • 64 Kbit SRAM
    • Reconfigurable I/O ports
    • Programmable power management.
