DS87C530/DS83C530 EPROM/ROM Microcontrollers with Real-Time Clock

DETAILED DESCRIPTION

The DS87C530/DS83C530 EPROM/ROM microcontrollers with a real-time clock (RTC) are 8051-

compatible microcontrollers based on the Dallas Semiconductor 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.
