GENERAL DESCRIPTION

The Z86C33/C43 Consumer Controller Processor (CCP™) is a member of Zilog's 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, costeffective 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.

The Z86C33/C43 features an Expanded Register File (ERF) to allow access to register-mapped peripheral and I/O circuits. Four basic address spaces are available to support this wide range of configurations: Program Memory, Register File, Data Memory, and ERF. The Register File is composed of 236 bytes of general-purpose registers, four I/O port registers, and 15 control and status registers. The ERF consists of three control registers

For applications demanding powerful I/O capabilities, the Z86C33 provides 24 pins, and the Z86C43 provides 32 pins dedicated to input and output. These lines are configurable under software control to provide timing,

status signals, parallel I/O with or without handshake, and address/data bus for interfacing external memory.

To unburden the system from coping with real-time tasks such as counting/timing and data communication, the Z86C33/C43 offers two on-chip counter/timers with a large number of user-selectable modes.

With ROM/ROMless selectivity, the Z86C43 provides both external memory and pre-programmed ROM, which enables this Z8 microcontroller to be used in high-volume applications, or where code flexibility is required.

Notes:

All Signals with a preceding front slash, "/", are active Low, e.g.: B//W (WORD is active Low); /B/W (BYTE is active Low, only).
