GENERAL DESCRIPTION

The Z86C90/C89 CCP? (Consumer Controller Processor) introduces a new level of sophistication to single-chip architecture. The Z86C90/C89 are ROMless members of the Z8 single-chip microcontroller family with 236 bytes of general purpose RAM.

The only difference that exists between the Z86C89 and the Z86C90 is that the on-chip oscillator of the Z86C89 can accept an external RC network or other external clock source, while the Z86C90s on-chip oscillator accepts a crystal, ceramic resonator, LC, or external clock source drive. The CCP controllers are housed in a 40-pin DIP, 44-pin Leaded Chip Carrier, or a 44-pin Quad Flat Pack, and are CMOS compatible. The CCP offers the use of external memory which enables this Z8 microcomputer to be used where code flexibility is required. Zilogs CMOS microcomputer offers fast execution, efficient use of memory, sophisticated interrupts, input/output bit manipulation capabilities, and easy hardware/software system expansion along with low cost and low power consumption.
