　　The DS87C530 is an 8051 compatible microcontroller based on the Dallas High Speed core. It uses four clocks per instruction cycle instead of 12 used by the standard 8051. It also provides a unique mix of peripherals not widely available on other processors. They include an on–chip Real Time Clock (RTC) and battery back up support for an on–chip 1K x 8 SRAM. The new Power Management Mode allows software to select reduced power operation while still processing.
　　A combination of high performance microcontroller core, real time clock, battery backed SRAM, and power management makes the DS87C530 ideal for instruments and portable applications. It also provides several peripherals found on other Dallas High–Speed Microcontrollers. These include two independent serial ports, two data pointers, on–chip power monitor with brown–out detection and a watchdog timer.
