GENERAL DESCRIPTION
The Z86L79/L80 family of IR (InfraRed) Controllers are
ROM-based members of the Z8
controller family with 237 bytes of general-purpose RAM.
The only differentiating factor between these two versions
is the availability of ROM. Zilog's CMOS microcontrollers
offer fast execution, efficient use of memory, sophisticated
interrupts, input/output bit manipulation capabilities, auto-
mated pulse generation/reception, and easy hard-
ware/software system expansion along with cost-effective
and low power consumption.
MCU
single-chip micro-
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
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.
