产品概述

The DS2250T-32-16+ is a soft microcontroller module in 40 pin SIMM package. It is a fully 8051 compatible 8bit CMOS microcontroller that offers softness in all aspects of its application. This is accomplished through comprehensive use of non-volatile technology to preserve all information in the absence of system VCC. The internal program/data memory space is implemented using 32Kbytes of non-volatile CMOS SRAM. Furthermore, internal data registers and key configuration registers are also non-volatile. An optional real time clock gives permanently powered timekeeping function. The clock keeps time to hundredth of second using an onboard crystal. All non-volatile memory and resources are maintained for over 10 years at room temperature in the absence of power. The DS2250T has on-chip full duplex serial I/O ports, two on-chip timer/event counters and 32 parallel I/O lines. The device is compatible with industry standard 8051 instruction set.
  • Supply voltage range from 4.75V to 5.25V
  • Operating temperature range from 0°C to 70°C
  • Supports UART interface and watchdog timer
  • Adapts to task at hand
  • 16MHZ crystal speed and 32KB RAM
  • Capable of modifying its own program and/or data memory in end use
  • High reliability operation
  • Power fail reset and early warning power fail interrupt
  • Initial downloading of software in end system via on-chip serial port
  • Software security, executes encrypted software to prevent unauthorized disclosure
