COP8SBE9/SCE9/SDE9

8-Bit CMOS Flash Microcontroller with 8k Memory,

Virtual EEPROM 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.
