Introduction

The PSD4000 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. PSD4000 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.
