GENERAL DESCRIPTION
The Z9021x Digital Television Controller (DTC) family is
Zilog’s latest and most powerful Z8-based DTC product offering. 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, dedicated I.R. capture registers, on-chip Analog-to-Digital conversion, and a hardware Master mode I
2
C interface. The familiar Z8 core in combination with these advanced features
makes the Z9021x family an ideal choice for low to midrange 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 communication 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 expanded register file space to offer greater flexibility in On
Screen Display creation.
