COP8AME9
8-Bit CMOS Flash Microcontroller with 8k Memory, Dual
Op Amps, Virtual EEPROM, Temperature Sensor, 10-Bit
A/D and Brownout Reset
1.0 General Description
The COP8AME9 Flash microcontroller is a highly integrated
COP8
Feature core device, with 8k Flash memory and
advanced features including Virtual EEPROM, dual Op
Amps (one programmable gain), temperature sensor, A/D,
High Speed Timers, USART, and Brownout Reset. The
COP8AME9 has True In-System Programmable Flash
memory with high-endurance (100k erase/write cycles), and
is well suited for applications requiring real-time data collec-
tion and processing, multiple sensory interface, and remote
monitoring. The same device is used for development, pre-
production and volume production with a range of COP8
software and hardware development tools.
