COP888xG/CS Family, 8-Bit CMOS ROM Based Microcontrollers with 4k to 24k Memory, Comparators and USART July 1999 COP888xG/CS Family 8-Bit CMOS ROM Based Microcontrollers with 4k to 24k Memory, Comparators and USART General Description Note: COP8SG devices are form-fit-function compatible supersets of the COP888xG/CL/CS Family devices, and are replacements for these in new designs, and design upgrades with minimum effort. The COP888xG ROM based microcontrollers are highly integrated COP8™ Feature core devices with larger memory (4k to 24k) and advanced features including two Analog comparators. These single-chip CMOS devices are suited for more complex applications requiring a full featured controller with a range of memory sizes, low EMI (except EG), comparators, and a full-duplex USART.
