DS87C530/DS83C530

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.
A combination of high performance microcontroller core, Real Time Clock, battery backed SRAM, and
power management makes the DS87C530/DS83C530 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.
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 16 kB 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 is a monolithic device. A user must supply an external battery or super-
cap and a 32.768 kHz timekeeping crystal to have permanently powered timekeeping or nonvolatile
RAM. The DS87C530/DS83C530 provides all the support and switching circuitry needed to manage
these resources.
