GENERAL DESCRIPTION

The Z86LX2/CX2 family of IR (Infrared) are ROM/ROM-

less-based members of the Z8 MCU single-chip micro-

offer fast execution, efficient use of memory, sophisticated

interrupts, input/output bit manipulation capabilities, auto-

mated pulse generation/reception, and internal key-scan

pull-up resistors. The Z86LX2/CX2 product line offers easy

hardware/software system expansion with cost-effective

and low power consumption.

controller family with 768 bytes of internal RAM. The differ-

entiating factor between these devices is the availability of

RAM, ROM and package options. The use of external

memory enables these Z8 microcontrollers to be used

where code flexibility is required. Offering the 5V versions

(Z86CXX) and gives optimum performance in both the low

and high voltage ranges. Zilog's CMOS microcontrollers

The Z86LX2/CX2 architecture is based on Zilog's 8-bit mi-

crocontroller core with an Expanded Register File to allow
