GENERAL DESCRIPTION
The Z86E7X family of IR (Infrared) CCP(Consumer Con-
troller Processor) are OTP-based members of the Z8® sin-
gle-chip microcontroller family with 256 or 768 bytes of
general-purpose RAM. The only differentiating factor be-
tween the E72/73 versions is the availability of RAM and
ROM. This EPROM Microcontroller family of OTP IR con-
trollers also offer the use of external memory which en-
ables this Z8 microcontroller to be used where code flexi-
bility is required. Zilog's CMOS microcontrollers offer fast
execution, efficient use of memory, sophisticated inter-
rupts, input/output bit manipulation capabilities, automated
pulse generation/reception, and easy hardware/software
system expansion along with cost-effective and low power
consumption.
The Z86E7X 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 CCP offers a flexible I/O
scheme, an efficient register and address space structure,
and a number of ancillary features that are useful in many
consumer, automotive, computer peripheral, and battery
operated hand-held applications.
CCPapplications demand powerful I/O capabilities. The
Z86L7X family fulfills this with five package options in
which the E72/73/L74 versions provide 31 pins of dedicat-
ed input and output. These lines are grouped into four
ports. Each port consists of eight lines (Port 3 has seven
lines of I/O and one Pref comparator input) and is config-
