COP884CGCOP888CG 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
