GENERAL DESCRIPTION
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/ C06 meets the needs of a variety of sophisticated controller applications (Figure 1).
