COP8CBR9/COP8CCR9/COP8CDR9
8-Bit CMOS Flash Microcontroller with 32k Memory,
Virtual EEPROM, 10-Bit A/D and Brownout
1.0 General Description
The COP8CBR/CCR/CDR9 Flash microcontrollers are
highly integrated COP8™ Feature core devices, with 32k
Flash memory and advanced features including Virtual EE-
PROM, A/D, High Speed Timers, USART, and Brownout
Reset. This single-chip CMOS device is suited for applica-
tions 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 produc-
tion with a range of COP8 software and hardware develop-
ment tools.
