COP8SBE9/SCE9/SDE9
8-Bit CMOS Flash Microcontroller with 8k Memory,
Virtual EEPROM and Brownout Reset
General Description
The COP8SBE9/SCE9/SDE9 Flash microcontrollers are
highly integrated COP8Feature core devices, with 8k
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.
