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.
