DESCRIPTION
The DS87C530/DS83C530 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.
