DESCRIPTION

STV9410 controller is a VLSI CMOS Display Processor. Time base generator, display control & refresh logic, interface for transparent MCU memory access, ROM character sets, memory to store display data & page codes and control registers are gathered on a single chip component packed in a short 20 DIP or SO plastic package.

Using its 3-wire serial interface, working in both read and write mode to program 7 control registers and to access internal RAM, STV9410 is a highly flexible processor.

The STV9410provides the user an easy to use and cost effective solution to display alphanumeric and semi graphic Information on CRT and LCD screens.
