COP888GW

The COP888GW family of microcontrollers uses an 8-bit single chip core architecture fabricated with National Semiconductor's M2CMOSTM process technology. The COP888GW 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 COP888GW include an 8-bit memory mapped architecture, MICROWIRE/ PLUS serial I/O, two 16-bit timer/counters supporting three modes (Processor Independent PWM generation, External Event counter and Input Capture mode capabilities), 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 independent of the HALT or IDLE modes.

Each I/O pin COP888GW 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 ICC filters on the chip logic and crystal oscillator. The device is available in 68-pin PLCC package.
