DETAILED DESCRIPTION
The DS87C530/DS83C530 EPROM/ROM microcontrollers with a real-time clock (RTC) are 8051-
compatible microcontrollers based on the Dallas high-speed core. They use 4 clocks per instruction cycle
instead of the 12 used by the standard 8051. They also provide a unique mix of peripherals not widely
available on other processors. They include an on-chip RTC and battery backup 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, RTC, battery-backed SRAM, and power
management makes the DS87C530/DS83C530 ideal for instruments and portable applications. They also
provide several peripherals found on other Dallas high-speed microcontrollers. These include two
independent serial ports, two data pointers, on-chip power monitor with brownout detection and a
watchdog timer.
Power Management Mode (PMM) allows software to select a slower CPU clock. While default operation
uses four clocks per machine cycle, the PMM runs the processor at 64 or 1024 clocks per cycle. There is a
corresponding drop in power consumption when the processor slows.
The EMI reduction feature allows software to select a reduced emission mode. This disables the ALE
signal when it is unneeded.
The DS83C530 is a factory mask ROM version of the DS87C530 designed for high-volume, cost-
sensitive applications. It is identical in all respects to the DS87C530, except that the 16kB of EPROM is
replaced by a user-supplied application program. All references to features of the DS87C530 will apply to
the DS83C530, with the exception of EPROM-specific features where noted. Please contact your local
Dallas Semiconductor sales representative for ordering information.
Note:
The DS87C530/DS83C530 are monolithic devices. A user must supply an external battery or super
cap and a 32.768kHz timekeeping crystal to have permanently powered timekeeping or nonvolatile RAM.
The DS87C530/DS83C530 provide all the support and switching circuitry needed to manage these
resources.
