DS2250 Description
The DS2250(T) Soft Microcontroller Module is a fully 8051 patible 8 bit CMOS microcontroller that offers “softness” in all aspects of its application. This is acplished through the prehensive use of nonvolatile technology to preserve all information in the absence of system VCC. The internal program/data memory space is implemented using 8K, 32K, or 64K bytes of nonvolatile CMOS SRAM.
DS2250 Key Features
- 8-bit 8051 patible microcontroller adapts to task
- 8K, 32K, or 64K 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
- High-reliability operation
- Maintains all nonvolatile resources for 10 years in the absence of VCC
- Power-fail reset
- Early warning power-fail interrupt
- Watchdog timer
- Software Security Feature
