1 / 75 page COP888EB 8-Bit CMOS ROM Based Microcontrollers with 8k Memory, CAN Interface, 8-Bit A/D, and USART General Description The COP888EB ROM based microcontrollers are highly in- tegrated COP8™ Feature core devices with 8k memory and advanced features including a CAN 2.0B (passive) interface, A/D and USART. These single-chip CMOS devices are suited for applications requiring a full featured controller with a CAN interface, low EMI, and versatile communications in- terfaces. COP87L8EB/RB devices are pin and software compatible 16k or 32k OTP (One Time Programmable) ver- sions for pre-production, and for use with a range of COP8 software and hardware development tools. Features include an 8-bit memory mapped architecture, 10 MHz CKI with 1µs instruction cycle, two multi-function 16-bit timer/counters, WATCHDOG™ and Clock Monitor, CAN 2.0B (passive) interface, MICROWIRE/PLUS™ serial I/O, SPI master/slave interface, fully buffered USART, 8-bit A/D with 8 channels, two power saving HALT/IDLE modes, MIWU, idle timer, software selectable I/O options, low EMI 4.5V to 5.5V operation, and 44/68 pin packages. Note: A companion device with CAN interface, less I/O and memory, and PWM timer is the COP888BC. Devices included in this datasheet are: Device Memory (bytes) RAM (bytes) I/O Pins Packages Temperature COP688EB 8k ROM 192 31 44 PLCC -55 to +125˚C COP888EB 8k ROM 192 31 44 PLCC -40 to +85˚C COP689EB 8k ROM 192 58 68 PLCC -55 to +125˚C COP889EB 8k ROM 192 58 68 PLCC -40 to +85˚C Key Features n CAN bus interface, with Software Power save mode n 8-bit A/D Converter with 8 channels n Fully buffered USART n Multi-input wake up (MIWU) on both Port L and M n SPI Compatible Master/Slave Interface n Quiet Design (Low Radiated Emissions) n 8096 bytes of on-board ROM n 192 bytes of on-board RAM Additional Peripheral Features n Idle timer (programmable) n Two 16-bit timer, with two 16-bit registers supporting — Processor independent PWM mode — External Event counter mode — Input capture mode n WATCHDOG and Clock Monitor n MICROWIRE/PLUS serial I/O I/O Features n Software selectable I/O options (TRI-STATE® outputs, Push pull outputs, Weak pull up input, High impedance input) n Schmitt trigger inputs on Port G, L and M n Packages: 44 PLCC with 31 I/O pins 68 PLCC with 58 I/O pins CPU/Instruction Set Features n 1 µs instruction cycle time n Fourteen multi-sourced vectored interrupts servicing — External interrupt — Idle Timer T0 — Timers (T1 and T2) (4 Interrupts) — MICROWIRE/PLUS and SPI — Multi-input Wake up — Software Trap — CAN interface (3 interrupts) — USART (2 Inputs) n Versatile easy to use instruction set n 8-bit stack pointer (SP) (Stack in RAM) n Two 8-bit Register Indirect Memory Pointers (B, X) Fully Static CMOS n Two power saving modes: HALT, IDLE n Single supply operation: 4.5V to 5.5V n Temperature ranges: −40˚C to +85˚C and −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 COP8™, MICROWIRE™, MICROWIRE/PLUS™, and WATCHDOG™ are trademarks of National Semiconductor Corporation.
