GENERAL DESCRIPTION
The Z9021x Digital Television Controller (DTC) family is
Zilog’s latest and most powerful Z8-based DTC product of-
fering. These parts feature larger system RAM and ROM
options, together with a host of new features including a
new color palette system, flexible inter-row spacing, higher
character cell resolution, background mesh effect, dedicat-
ed I.R. capture registers, on-chip Analog-to-Digital conver-
sion, and a hardware Master mode I
2
C interface. The fa-
miliar Z8 core in combination with these advanced features
makes the Z9021x family an ideal choice for low to mid-
range televisions in both PAL and NTSC markets.
The Z9021x family consists of two basic device types;
Z9020x and Z9021x. The only difference between the two
types is the presence of a hardware I
2
C serial communica-
tion port and half-tone OSD circuitry on the Z9021x family.
Of course I
2
C communication is supported on the Z9020x
family in software with the dedication of any two I/O pins to
the task.
The Z9021x family takes full advantage of the Z8’s ex-
panded register file space to offer greater flexibility in On
Screen Display creation.
