Application overview

The MB87J2120 Lavender and MB87P2020-A “Jasmine” are colour LCD/CRT graphic display controllers (GDCs)1 interfacing to MB91xxxx micro controller family and support a wide range of display devices. The architecture is designed to meet the low cost, low power requirements in embedded and especially in automotive2 applications.

Lavender and Jasmine support almost all LCD panel types and CRTs or other progressive scanned3 monitors/displays which can be connected via the digital or analog RGB output. Products requiring video/camera input can take advantage of the supported digital video interface. The graphic instruction set is optimized for minimal traffic at the MCU interface because it’s the most important performance issue of co-processing graphic acceleration systems. Lavender uses external connected SDRAM, Jasmine is a compatible GDC version with integrated SDRAM (1MByte) and comes with additional features.

Lavender and Jasmine support a set of 2D drawing functions with built in Pixel Processor, a video scaler interface, units for physical and direct video memory access and a powerful video output stream formatter for the greatest variety of connectable displays.
