GENERAL DESCRIPTION

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.

Note: 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).

Power connections follow conventional descriptions below:

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 I/O.

■ 32 Input/Output Lines (Three with Comparator Inputs)

(Z86243 Only)

■ Vectored, Prioritized Interrupts with Programmable

Polarity

■ Two Comparators

■ Two Programmable 8-Bit Counter/Timers, Each

with a 6-Bit Programmable Prescaler

■ Watch-Dog Timer (WDT)/Power-On Reset (POR)

■ On-Chip Oscillator that Accepts a Crystal, Ceramic

Resonator, LC, RC, or External Clock Drive

■ RAM and ROM Protect

■ Clock Free Watch-Dog Timer (WDT) Reset
