DS87C530
022197 2/40
A combination of high performance microcontroller
core, real time clock, battery backed SRAM, and power
management makes the DS87C530 ideal for instru-
ments and portable applications. It also provides sev-
eral 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 pro-
cessor at 64 or 1024 clocks per cycle. There is a corre-
sponding drop in power consumption when the proces-
sor slows.
Note: The DS87C530 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 provides all the support and switching cir-
cuitry needed to manage these resources.
