021998 1/19
FEATURES
8–bit 8051 compatible Microcontroller adapts to task–
at–hand:
– 8 or 32K bytes of nonvolatile RAM for program
and/or data memory storage
– Initial downloading of software in end system
via on–chip serial port
– Capable of modifying its own program and/or
data memory in end use
Crashproof operation:
– Maintains all nonvolatile resources for 10 years
in the absence of V
CC
– Power–fail reset
– Early warning power–fail interrupt
– Watchdog timer
Software Security Feature:
– Executes encrypted software to prevent unau-
thorized disclosure
On–chip, full–duplex serial I/O ports
Two on–chip timer/event counters
32 parallel I/O lines
Compatible with industry standard 8051 instruction
set and pinout
Optional Permanently Powered Real–Time Clock

DESCRIPTION
The DS5000(T) Soft Microcontroller Module is a fully
8051 compatible 8–bit CMOS microcontroller that offers
“softness” in all aspects of its application. This is ac-
complished through the comprehensive use of nonvola-
tile technology to preserve all information in the ab-
sence of system V
CC
. The internal program/data
memory space is implemented using either 8K or
32K bytes of nonvolatile CMOS SRAM. Furthermore,
internal data registers and key configuration registers
are also nonvolatile. An optional real time clock gives
permanently powered timekeeping. The clock keeps
time to a hundredth of a second using an on–board
crystal.
