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.
