Introduction
The PSD9XX family of Programmable System Devices (for 8-bit microcontrollers) brings In-System-Programmability (ISP) to Flash memory and programmable logic. The result is a simple and flexible solution for embedded designs. PSD9XX devices combine many of the peripheral functions found in MCU based applications:
   • Up to 2 Mbit of Flash memory
   • A secondary 256 Kbit Flash memory
   • Over 2,000 gates of Flash programmable logic
   • Up to 256 Kbit SRAM
   • Reconfigurable I/O ports
   • Programmable power management.
