DS2 Family DS2250 Series Microcontrollers 8位微控制器:

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 VCC. The internal program/data memory space is implemented using 8, 32, or 64kB of nonvolatile CMOS SRAM.
