GENERAL DESCRIPTION
The Z86L7X family of IR (Infrared)/Low-Voltage Microcon-
trollers are ROM/ROMless-based members of the Z8®
MCU single-chip family with 237/125 bytes of internal
RAM. The differentiating factor between these devices is
the availability of RAM, ROM and package options. Offer-
ing the 3V versions (Z86LXX) with the Z86C71 gives opti-
mum performance in both the low and high voltage ranges.
Zilog's CMOS Low-Voltage Microcontrollers offer fast exe-
cution, efficient use of memory, sophisticated interrupts, in-
put/output bit manipulation capabilities, automated pulse
generation/reception, and internal key-scan pull-up resis-
tors. The Z86L7X product line offers easy hardware/soft-
ware system expansion with cost-effective and low power
consumption.
The Z86L7X architecture is based on Zilog's 8-bit micro-
controller core with an Expanded Register File to allow ac-
cess to register mapped peripherals, I/O circuits, and pow-
erful counter/timer circuitry. The Z8® MCU offers a flexible
I/O scheme, an efficient register and address space struc-
ture, and a number of ancillary features that are useful in
many consumer, automotive, computer peripheral, and
battery operated hand-held applications.
There are three basic address spaces available to support
a wide range of configurations: Program Memory, Register
File, and Expanded Register File. The register file is com-
posed of 256/144 bytes of RAM. It includes four I/O port
registers, 15 control and status registers and the rest are
General-Purpose registers. The Expanded Register File
consists of two additional register groups (F and D). Exter-
nal Memory is not available on 18 and 20-pin versions.

Stresses greater than those listed under Absolute Maxi-
mum Ratings may cause permanent damage to the de-
vice. This is a stress rating only; operation of the device at
any condition above those indicated in the operational sec-
tions of these specifications is not implied. Exposure to ab-
solute maximum rating conditions for an extended period
may affect device reliability.
