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.  
I/O Features  
n Memory mapped I/O  
n Software selectable I/O options ( TRI-STATE Output,  
Push-Pull Output, Weak Pull-Up Input, High Impedance  
Input)  
The COP888 family of microcontrollers uses an 8-bit single  
n High current outputs  
n Schmitt trigger inputs on port G  
chip core architecture fabricated with National Semiconduc-  
2
™
tor’s M CMOS process technology. The COP888CL is a  
member of this expandable 8-bit core processor family of  
microcontrollers.  
n Packages:  
— 44 PLCC with 40 I/O pins  
— 40 DIP with 36 I/O pins  
— 28 DIP with 24 I/O pins  
— 28 SO with 24 I/O pins  
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 µs per  
instruction rate.  
CPU/Instruction Set Feature  
n 1 µs instruction cycle time  
n Ten multi-source vectored interrupts servicing  
— External Interrupt with selectable edge  
— Idle Timer T0  
— Timers (Each with 2 interrupts)  
— MICROWIRE/PLUS  
— Multi-Input Wake Up  
— Software Trap  
— Default VIS (default interrupt)  
n Versatile and easy to use instruction set  
n 8-bit Stack Pointer (SP)—stack in RAM  
n Two 8-bit Register Indirect Data Memory Pointers (B, X)  
Key Features  
n Two 16-bit timers, each with two 16-bit registers  
supporting:  
— Processor Independent PWM mode  
— External Event counter mode  
— Input Capture mode  
Fully Static CMOS  
<
n Low current drain (typically 1 µA)  
n Single supply operation: 2.5V to 6.0V  
n Temperature ranges: 0˚C to +70˚C, −40˚C to +85˚C,  
−55˚C to +125˚C  
n 4 kbytes of on-chip ROM  
n 128 bytes of on-chip RAM  
Additional Peripheral Features  
n Idle Timer  
n Multi-input Wake Up (MIWU) with optional interrupts (8)  
n WATCHDOG and Clock Monitor logic  
Development Support  
n Emulation and OTP devices  
n Real time emulation and full program debug offered by  
MetaLink Development System  
™
n MICROWIRE/PLUS serial I/O
