Automotive 80 x 4 LCD Driver for Low Multiplex Rates

The PCA85233 is a peripheral device which interfaces to almost any Liquid Crystal Display (LCD)1 with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 80 segments and can easily be cascaded for larger LCD applications. The PCA85233 is compatible with most microcontrollers and communicates via the two-line bidirectional I2C-bus. Communication overheads are minimized by a display RAM with auto-incremental addressing, by hardware subaddressing, and by display memory switching.

ROM-based low-power DisplayPort to VGA Adapter

NXP introduces a ROM-based DisplayPort to VGA adapter optimized primarily for motherboard applications, PTN3356R1. The device is designed to convert a DisplayPort signal from the chip set to an analog video signal that directly connects to the VGA connector. PTN3356R1 also aids in monitor detection by performing load sensing on RGB lines and reporting sink connection status to the source.
