GENERAL DESCRIPTION
The Z86L8X family of infrared (IR) consumer controller
processors are ROM-based members of the Z8
single-
chip microcontroller family offering a unique register-to-
register architecture that avoids accumulator bottlenecks
and offers fast execution of code.
Zilog's CMOS microcontrollers feature fast execution,
efficient use of memory, sophisticated interrupts, input/
output bit manipulation capabilities, automated pulse
generation/reception, and easy hardware/software system
expansion along with low-cost and low-power consumption.
The Z86L8X family architecture is based on Zilog's 8-bit
microcontroller core with an Expanded Register File (ERF)
to allow access to register mapped peripherals, I/O circuits,
and powerful counter/timer circuitry. The Z86L8X 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.
