COP888GW  
8-Bit Microcontroller with Pulse Train Generators  
and Capture Modules  
General Description  
The COP888 family of microcontrollers uses an 8-bit single  
Additional Peripheral Features  
Y
Idle Timer  
Y
chip core architecture fabricated with National Semiconduc-  
2
Multi-Input Wake-Up (MIWU) with optional interrupts (8)  
MICROWIRE/PLUSTM serial I/O  
tor’s M CMOSTM process technology. The COP888GW is a  
Y
member of this expandable 8-bit core processor family of  
microcontrollers. It is a fully static part, fabricated using dou-  
ble-metal silicon gate microCMOS technology.  
I/O Features  
Y
Memory mapped I/O  
Features include an 8-bit memory mapped architecture, MI-  
CROWIRE/PLUS serial I/O, two 16-bit timer/counters sup-  
porting three modes (Processor Independent PWM genera-  
tion, External Event counter and Input Capture mode capa-  
bilities), 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 capabili-  
ty. This multi-sourced interrupt capability may also be used  
independent of the HALT or IDLE modes.  
Y
Software selectable I/O options (TRI-STATE Output,  
É
Push-Pull Output, Weak Pull-Up Input, High Impedance  
Input)  
Y
Schmitt trigger inputs on port G  
Y
Package: 68-pin PLCC  
CPU/Instruction Set Features  
Y
1 ms instruction cycle time  
Y
Fourteen multi-source vectored interrupts servicing:  
Ð External Interrupt with selectable edge  
Ð Idle Timer T0  
Ð Two Timers (each with 2 interrupts)  
Ð MICROWIRE/PLUS  
Ð Multi-Input Wake-Up  
Ð Software Trap  
Ð UART (2)  
Ð Capture Timers  
Ð Counters (one vector for all four counters)  
Ð Default VIS (default interrupt)  
Each I/O pin has software selectable configurations. The  
devices 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 ms per instruction rate. The  
device has low EMI emissions. Low radiated emissions are  
achieved by gradual turn-on output drivers and internal I  
CC  
filters on the chip logic and crystal oscillator. The device is  
available in 68-pin PLCC package.
