GENERAL DESCRIPTION

The Z86C3X/C40 Consumer Controller Processors (CCP) are members of the Z8® single-chip microcontroller family offering a unique register-to-register architecture that avoids accumulator bottlenecks and offers fast execution of code.

Three address spaces (Program Memory, Register File, and Expanded Register File [ERF]), support a wide range of memory configurations. Through the ERF, the designer has access to three additional control registers that provide extra peripheral devices, I/O ports, and register addresses. The rest of the ERF is not physically implemented and is open for future expansion.

For applications demanding powerful I/O capabilities, the Z86C3X/C40's dedicated input and output lines are grouped into three and four ports, respectively, and are configurable under software control to provide timing, status signals, or parallel I/O.

Two on-chip counter/timers, with a large number of selectable modes, offload the system of administering real-time tasks such as counting/timing and I/O data communications.

With ROM/ROMless selectivity, the Z86C40 provides both external memory and pre-programmed ROM, which enables these Z8 microcontrollers to be used in highvolume 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).
