COP888GW
8-Bit Microcontroller with Pulse Train Generators and
Capture Modules
General Description
The COP888 family of microcontrollers uses an 8-bit single
chip core architecture fabricated with National Semiconduc-
tor’s M
2
CMOS
process technology. The COP888GW is a
member of this expandable 8-bit core processor family of mi-
crocontrollers. 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 (Processor Independent PWM gen-
eration, External Event counter and Input Capture mode ca-
pabilities), four independent 16-bit pulse train generators
with 16-bit prescalers, two independent 16-bit input capture
modules with 8-bit prescalers, multiply and divide functions,
full duplex UART, and two power savings modes (HALT and
IDLE), both with a multi-sourced wake up/interrupt capability.
This multi-sourced interrupt capability may also be used in-
dependent of the HALT or IDLE modes.
Each I/O pin has software selectable configurations. The de-
vices operate over a voltage range of 2.5V–6V. High
throughput is achieved with an efficient, regular instruction
set operating at a maximum of 1 μs per instruction rate. The
device has low EMI emissions. Low radiated emissions are
achieved by gradual turn-on output drivers and internal I
filters on the chip logic and crystal oscillator. The device is
available in 68-pin PLCC package.
