PSD835G2-90U

片上可配置存储系统的8位微控制器 Configurable Memory System on a Chip for 8-Bit Microcontrollers

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.
