Z90212

The Z90212 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 I2C 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 Z90212 family consists of two basic device types; Z9020x and Z9021x. The only difference between the two types is the presence of a hardware I2C serial communication port and half-tone OSD circuitry on the Z9021x family. Of course I2C communication is supported on the Z9020x family in software with the dedication of any two I/O pins to the task.

The Z90212 family takes full advantage of the Z8's expanded register file space to offer greater flexibility in On Screen Display creation.
