This document provides information on a new product under development or evaluation. The product is a multifunctional monitor that includes features for screen size and centering auto setup, measurements of horizontal sync, vertical sync, and video timing signals up to 100MHz pixel clock. It has a character ROM font, allowing for the display of custom characters and text. The product also features an I2C bus MCU interface and five 8-bit PWM DAC outputs.
The STV9432TAP is a multifunction slave peripheral device connected to a host MCU via its serial I²C Bus. It integrates blocks for On-Screen Display (OSD), Cut-off Monitoring Circuitry, and Video Timing Analyzer. The OSD includes a mask programmable ROM for custom character fonts and 1Kbytes of RAM for storing text code strings.
