2 / 42 page  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 2CMOS™ 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 µs per instruction rate. 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 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 n MICROWIRE/PLUS™ serial I/O 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) n High current outputs n Schmitt trigger inputs on port G 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 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) 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 Development Support n Emulation and OTP devices n Real time emulation and full program debug offered by MetaLink Development System MICROWIRE/PLUS™,M2CMOS™, COPS™ microcontrollers, and MICROWIRE™ are trademarks of National Semiconductor Corporation. iceMASTER™ is a trademark of MetaLink Corporation.
