The COP8SBR9/SCR9/SDR9 Flash based microcontrollers are highly integrated COP8™ Feature core
devices, with 32k Flash memory and advanced features including Virtual EEPROM, High Speed Timers,
USART, and Brownout Reset. This single-chip CMOS device is suited for applications requiring 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.
