DESCRIPTION
The DS87C530/DS83C530 EPROM/ROM Micro with Real Time Clock is an 8051-compatible microcontroller based on the Dallas high-speed core. It uses 4 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.
