GENERAL DESCRIPTION
The Z86LXX family of IR (Infrared) CCP
鈩?/div>
(Consumer Con-
troller Processor) Controllers are ROM/ROMless-based
members of the Z8
廬
single-chip microcontroller family with
256 bytes of internal RAM. The differentiating factor be-
tween these devices is the availability of ROM, and pack-
age options. For the 40 and 44-pin devices the use of ex-
ternal memory enables these Z8 microcontrollers to be
used where code flexibility is required. Zilog鈥檚 CMOS mi-
crocontrollers offers fast executing, efficient use of memo-
ry, sophisticated interrupts, input/output bit manipulation
capabilities, automated pulse generation/reception, and in-
DS96LV00800
ternal key-scan pull-up resistors. The Z86LXX product line
offers easy hardware/software system expansion cost-ef-
fective and low power consumption.
The Z86LXX 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
