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.
