Product Overview

The DS87C530-QCL+ is an EPROM/ROM microcontroller with real-time clock in 52 pin PLCC package. It is an 8051 compatible microcontrollers based on the Dallas Semiconductor high speed core. It uses 4 clocks per instruction cycle instead of the 12 used by the standard 8051. It also provides a unique mix of peripherals not widely available on other processors. It has an on-chip RTC and battery backup support for an on-chip 1K x 8 SRAM. The new Power Management Mode (PMM) allows software to select reduced power operation while still processing. A combination of high-performance microcontroller core, RTC, battery-backed SRAM and power management makes the DS87C530 ideal for instruments and portable applications. It includes two independent serial ports, two data pointers, on-chip power monitor with brownout detection and a watchdog timer. PMM allows software to select a slower CPU clock. While default operation uses four clocks per machine cycle, the PMM runs at 64 or 1024 clocks per cycle.
  • Supply voltage range is 4.5V to 5.5V
  • Operating temperature range from 0°C to 70°C
  • Four 8bit I/O ports and 256bytes scratchpad RAM
  • 16KB EPROM (OTP) and 1KB extra on-chip SRAM for MOVX
  • Selects effective on-chip ROM size from 0 to 16KB
  • Runs DC to 33MHz clock rates
  • Single-cycle instruction in 121ns
  • EMI reduction mode disables ALE
  • Two full duplex hardware serial ports
  • 14 total interrupt sources with six external
