GENERAL DESCRIPTION

The Z86C33/C43 Consumer Controller Processor (CCP?) is a member of Zilogs Z8? single-chip microcontroller family with enhanced wake-up circuitry, programmable Watch-Dog Timers (WDT), and low-noise/EMI options. These enhancements result in a more efficient, cost effective design and provide the user with increased design flexibility over the standard Z8 microcontroller core. This low-power consumption CMOS microcontroller offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion.
