8-Bit CMOS Flash Microcontroller with 32k Memory, 1 k RAM, Virtual EEPROM, and 4.17V to 4.5V Browno

8-Bit CMOS Flash Microcontroller with 32k Memory, 1 k RAM, Virtual EEPROM, and 4.17V to 4.5V Browno - COP8SCR9


The COP8SBR9/SCR9/SDR9 Flash based microcontrollers are highly integrated COP8 Feature core devices, with 32k Flash memory and advanced features including Virtual EEPROM, High Speed Timers, USART, and Brownout Reset. This single-chip CMOS device is suited for applications 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 production with a range of COP8 software and hardware development tools.
