GENERAL DESCRIPTION
The Z86LX2/CX2 family of IR (Infrared) are ROM/ROM-
less-based members of the Z8® MCU single-chip micro-
controller family with 768 bytes of internal RAM. The differ-
entiating factor between these devices is the availability of
RAM, ROM and package options. The use of external
memory enables these Z8 microcontrollers to be used
where code flexibility is required. Offering the 5V versions
(Z86CXX) and gives optimum performance in both the low
and high voltage ranges. Zilog's CMOS microcontrollers
offer fast execution, efficient use of memory, sophisticated
interrupts, input/output bit manipulation capabilities, auto-
mated pulse generation/reception, and internal key-scan
pull-up resistors. The Z86LX2/CX2 product line offers easy
hardware/software system expansion with cost-effective
and low power consumption.
The Z86LX2/CX2 architecture is based on Zilog's 8-bit mi-
crocontroller core with an Expanded Register File to allow

GENERAL DESCRIPTION (Continued)
access to register mapped peripherals, I/O circuits, and
powerful counter/timer circuitry. The Z86C72/C92/L72/L92
offers a flexible I/O scheme, an efficient register and ad-
dress space structure, and a number of ancillary features
that are useful in many consumer, automotive, computer
peripheral, and battery operated hand-held applications.
Many applications demand powerful I/O capabilities. The
Z86LX2/CX2 family fulfills this with three package options
in which the L72 version provides 31 pins of dedicated in-
put and output. These lines are grouped into four ports.
Each port consists of eight lines (Port 3 has seven lines)
and is configurable under software control to provide tim-
ing, status signals, parallel I/O with or without handshake,
and an address/data bus for interfacing external memory.
There are five basic address spaces available to support a
wide range of configurations: Program Memory, Register
Zilog
File, Expanded Register File, Extended Data RAM and Ex-
ternal Memory. The register file is composed of 256 bytes
of RAM. It includes four I/O port registers, 16 control and
status registers and the rest are General-Purpose regis-
ters. The Extended Data RAM adds 512 bytes of usable
general-purpose registers. The Expanded Register FIle
consists of two additional register groups (F and D).
To unburden the program from coping with such real-time
problems as generating complex waveforms or receiving
and demodulating complex waveform/pulses, the
Z86LX2/CX2 family offers a new intelligent counter/timer
architecture with 8-bit and 16-bit counter/timers (Figure 1).
Also included are a large number of user-selectable
modes, and two on-board comparators to process analog
signals with separate reference voltages (Figure 2).
