COP8SBR9/COP8SCR9/COP8SDR9  
8-Bit CMOS Flash Based Microcontroller with 32k  
Memory, Virtual EEPROM and Brownout  
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.  
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.
