DESCRIPTION
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鈥揷hip Real Time Clock (RTC) and battery back up
support for an on鈥揷hip 1K x 8 SRAM. The new Power
Management Mode allows software to select reduced
power operation while still processing.

鈥?Programmable Watchdog timer
