DS87C530/DS83C530
070898 2/41
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 pro-
vides several peripherals found on other Dallas High–
Speed Microcontrollers. These include two indepen-
dent 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 pro-
cessor at 64 or 1024 clocks per cycle. There is a corre-
sponding drop in power consumption when the proces-
sor slows.
The EMI reduction feature allows software to select a re-
duced 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 re-
placed by a user–supplied application program. All ref-
erences to features of the DS87C530 will apply to the
DS83C530, with the exception of EPROM–specific fea-
tures where noted. Please contact your local Dallas
Semiconductor sales representative for ordering in-
formation.
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 per-
manently powered timekeeping or nonvolatile RAM.
The DS87C530/DS83C530 provides all the support and
switching circuitry needed to manage these resources.
