1 / 80 page COP8SBR9/COP8SCR9/COP8SDR9 8-Bit CMOS Flash Based Microcontroller with 32k Memory, Virtual EEPROM and Brownout 1.0 General Description The COP8SBR9/SCR9/SDR9 Flash based microcontrollers are highly integrated COP8™ Feature core devices, with 32k Flash memory and advanced features including Virtual EE- PROM, High Speed Timers, USART, and Brownout Reset. This single-chip CMOS device is suited for applications re- quiring a full featured, in-system reprogrammable controller with large memory and low EMI. The same device is used for development, pre-production and volume production with a range of COP8 software and hardware development tools.
