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 COP8TM 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 Device described in this datasheet: Flash Program Memory (bytes) 8k RAM (bytes) 512 Brownout Voltage 4.17 to 4.5V I/O Pins 21 memory with high-endurance (100k erase/write cycles), and is well suited for applications requiring real-time data collection and processing, multiple sensory interface, and remote monitoring. The same device is used for development, preproduction and volume production with a range of COP8 software and hardware development tools.
