COP884CG COP888CG 8-Bit Microcontroller
with UART and Three Multi-Function Timers
General Description
The COP888 family of microcontrollers uses an 8-bit single
chip core architecture fabricated with National Semiconduc-
tor’s M2CMOSTM process technology The COP888CG is a
member of this expandable 8-bit core processor family of
microcontrollers
