产品概述

The DS89C450-QNG+ from Maxim Integrated Products is an ultra high speed flash microcontroller in 44 pin PLCC package. It is a standard 8051 compatible microcontroller. The newly designed processor cores that execute instructions up to 12 times faster than the original 8051 at the same crystal speed. Typical applications have a speed improvement of up to 10 times. At 1MIPS/MHz, the microcontrollers achieve 33MIPS performance from a maximum 33MHz clock rate. It include 1KB of data RAM, a second full hardware serial port, seven additional interrupts, two extra levels of interrupt priority, programmable watchdog timer, brownout monitor and power-fail reset. The speed of MOVX data memory access can be adjusted by adding stretch values up to 10 machine cycles for flexibility in selecting external memory and peripherals. Applications include data logging, white goods, magstripe reader/scanner, telephones, HVAC, vending and automotive test equipments.
  • Supply voltage range is 4.5V to 5.5V, supply current in active mode is 75mA
  • Operating temperature range from -40°C to 85°C
  • Internal flash memory size is 64KB x 8, maximum clock speed is 25MHz
  • Single cycle instruction in 30ns, three 16bit timer counters, four bidirectional 8bit I/O ports
  • Supports four paged memory-access modes
  • 256byte scratchpad RAM
  • Programmable clock divider
  • Automatic hardware and software exit
  • Dynamically adjustable by software, allows access to entire external memory map
  • Dual data pointers are included with automatic increment/decrement and toggle select operation
