GENERAL DESCRIPTION
The Z86LX2/CX2 family of IR (Infrared) are ROM/ROM-
less-based members of the Z8
廬
MCU single-chip micro-
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
DS97LVO0900
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.
The Z86LX2/CX2 architecture is based on Zilog's 8-bit mi-
crocontroller core with an Expanded Register File to allow
