parators, and zero external components. These single-chip
CMOS devices are suited for more complex applications re-
quiring a full featured controller with larger memory, low EMI,
two comparators, and a full-duplex USART. COP8FGx7 de-

(One Time Programmable) versions for use in production or
development.
