DS2250(T)
Soft Microcontroller Module

DESCRIPTION
The DS2250(T) soft microcontroller module is a
fully 8051-compatible 8-bit CMOS microcontroller that
offers “softness” in all aspects of its application.
This is accomplished through the comprehensive
use of nonvolatile technology to preserve all
information in the absence of system V
CC
. The
internal
program/data
memory
space
is
implemented using 8, 32, or 64kbytes 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.
All nonvolatile memory and resources are
maintained for over 10 years at room temperature in
the absence of power.
FEATURES
8-Bit 8051-Compatible Microcontroller
Adapts to Task-At-Hand
8, 32, or 64kbytes 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
High-Reliability Operation
Maintains All Nonvolatile Resources Up to 10
Years in the Absence of V
CC

Temperature
Power-Fail Reset
Early Warning Power-Fail Interrupt
Watchdog Timer
Software Security Feature
Executes Encrypted Software to Prevent
Unauthorized 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
