COP8CFE9
8-Bit CMOS Flash Microcontroller with 8k Memory,
Virtual EEPROM, and 10-Bit A/D
General Description
The COP8CFE9 Flash microcontroller is a highly integrated
COP8™ Feature core device, with 8k Flash memory and
advanced features including Virtual EEPROM, A/D, and High
Speed Timers. This single-chip CMOS device is suited for
applications requiring a full featured, in-system reprogram-
mable 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.
