COP884EG

The COP8TM feature family of microcontrollers use an 8-bit single-chip core architecture fabricated with National Semiconductor's M2CMOSTM process technology. The COP888EG/COP884EG are members of this expandable 8-bit core processor family of microcontrollers.They are fully static parts, fabricated using double-metal silicon gate microCMOS technology. Features of COP884EG include an 8-bit memory mapped architecture, MICROWIRE/PLUS serial I/O, three 16-bit timer/counters supporting three modes (Processor Independent PWM generation, External Event counter, and Input Capture mode capabilities), full duplex UART, two comparators, and two power savings modes (HALT and IDLE), both with a multi-sourced wakeup/interrupt capability. This multi-sourced interrupt capability may also be used independent of the HALT or IDLE modes.

Each I/O pin has software selectable configurations. COP884EG operates over a voltage range of 2.5V to 6V. High throughput is achieved with an efficient, regular instruction set operating at a maximum rate of 1 ms per instruction. Low radiated emissions are achieved by gradual turn-on output drivers and internal ICC smoothing filters on the chip logic and crystal oscillator.
