COP888CL
8-Bit Microcontroller
General Description
The following part numbers are pin count and tempera-
ture
variations
of
the
COP888CL:
COP688CL,
COP684CL, COP884CL, COP988CL, COP984CL.
The COP888 family of microcontrollers uses an 8-bit single
chip core architecture fabricated with National Semiconduc-
tor's M
2
CMOS
TM
process technology. The COP888CL is a
member of this expandable 8-bit core processor family of
microcontrollers.
It is a fully static part, fabricated using double-metal silicon
gate microCMOS technology. Features include an 8-bit
memory mapped architecture, MICROWIRE/PLUS serial
I/O, two 16-bit timer/counters supporting three modes (Pro-
cessor Independent PWM generation, External Event
counter, and Input Capture mode capabilities), and two
power savings modes (HALT and IDLE), both with a multi-
sourced wakeup/interrupt capability. This multi-sourced in-
terrupt capability may also be used independent of the HALT
or IDLE modes. Each I/O pin has software selectable con-
figurations. The device operates over a voltage range of
2.5V to 6V. High throughput is achieved with an efficient,
regular instruction set operating at a maximum of 1 s per
instruction rate.
