DS83C530, DS87C530 EPROM Microcontrollers With Real-Time Clock

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, costsensitive 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.
