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 bottlenecksand offers fast execution of code.

Three address spaces (Program Memory, Register File, and Expanded Register File [ERFj), 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 l/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-lime tasks such as counting/timing and JIG 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 high volume
applications, or where code flexibility is required.
