The Z86233/243 Consumer Controller Processor is a member of Zilog´s Z8 single-chip microcontroller family featuring enhanced wake-up circuitry, programmable Watch-Dog timers and low-EMI options. The parts provide flexible and efficient growth paths for designers currently using the 4K ROM versions of the consumer controller devices (Z86C30/C40/C33/C43).

Four address spaces, the Program Memory. Register File, Data Memory and Expanded Register File (ERF), support a wide range of memory configurations. Through the ERF, the designer has access to two additional control registers which provide extra peripheral devices, I/O ports, and register addresses.

For applications demanding powerful I/O capabilities, the Z86243 provides 32 pins dedicated to input and output. The Z86233 provides 24 pins dedicated to input and output. These lines are grouped into four ports with eight lines each, and are configurable under software control to provide timing, status signals, or parallel 1/0.

With ROM/ROMless selectivity, the Z86243 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.
