The Z86C03/C06 CCP™ (Consumer Controller Processors) are members of Zilog's the Z8® single-chip microcontroller family with enhanced wake-up circuitry, programmable watch-dog timers and low noise/EMI options.
These enhancements result in a more efficient, costeffective design and provide the user with increased
design flexibility over the standard Z8 microcontroller
core. With 512 and 1K bytes of ROM and 60 and 124 bytes
of general-purpose RAM, respectively, these low cost, low
power consumption CMOS microcontrollers offer fast execution, efficient use of memory, sophisticated interrupts,
input/output bit manipulation capabilities, and easy hardware/software system expansion.

The Z86C03/C06 CCP architecture is characterized by
Zilog’s 8-bit microcontroller core with the addition of an
Expanded Register File to allow easy access to register
mapped peripheral and I/O circuits. The Z86C03/C06
offers a flexible I/O scheme, an efficient register and
address space structure, and a number of ancillary features that are useful in many consumer, automotive, and
industrial applications.
For applications demanding powerful I/O capabilities, the
Z86C03/C06 provides 14 pins dedicated to input and
output. These lines are grouped into two ports and are
configurable under software control to provide timing,
status signals, or parallel I/O.

GENERAL DESCRIPTION (Continued)
Three basic address spaces are available to support this
wide range of configurations: Program Memory, Register
File, and Expanded Register File. The Register File is
composed of 61/125 bytes of General-Purpose Registers,
two I/O Port registers, and 12/14 Control and Status registers. The Expanded Register File consists of three control
registers in the Z86C03, and four control registers, a SPI
Receive Buffer, and a SPI compare register in the Z86C06.
With powerful peripheral features such, as on-board comparators, counter/timer(s), Watch-Dog Timer (WDT), and
Serial Peripheral Interface (SPI) (C06 only), the Z86C03/
Z86C03/C06 CMOS Z8
