RAiO / RA8860
The RA8860 is a LCD Driver & Controller for Field Sequential Liquid Crystal Display (FSLCD) application. It contains 80 segments and 2 commons driver circuits. And each dot supports 8 or 16 colors individually. This chip is connected directly to a MCU, support 3-wire, 4-wire serial peripheral interface (SPI) and I2C interface, display data can stores in an on-chip display data RAM of 640bits. It performs display data RAM read/write operation with no external operating clock to minimize power consumption..
In addition, RA8860 also supports LED driving signals to generate RGB LED backlight system if necessary. RA8860 supports multi-chip using as serial connected and is realized by setting the hardware pins. The maximum cascade level is eight, that means could support 640x2 dots for LCD panel. For traditional TN display, RA8860 is a cheap and best choice to make mono TN to Color solution
