Description

The COP888 family of microcontrollers uses an 8-bit single chip core architecture fabricated with National Semiconductor's M2CMOSTM process technology. The COP888CL is a member of this expandable 8-bit core processor family of microcontrollers. (Continued)

The following part numbers are pin count and temperature 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 Semiconductor's M²CMOS™ process technology. The COP888CL is a member of this expandable 8-bit core processor family of microcontrollers.

COP888CL 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 (Processor Independent PWM generation, External Event counter, and Input Capture mode capabilities), and two power savings modes (HALT and IDLE), both with a multisourced 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. 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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
