General Description The CY2890- AFB and BFA are digital TFT-LCD timing controllers with built-in “dithering”, “reverse”, “dual”, “flicker”, “AP” and “pattern generator” functions. The input signal is digital R/G/B with HSYNC/VSYNC or DE. User can use the MODE pin to select input signal to be either HSYNC mode or DE mode. The R/G/B input is fixed to 8 bits data width and the output is always 6 bits. The convert from 8 bits RGB to 6 bits RGB can be either directly truncated or dithering depends on the “DITHER” function is off or on. When DITHER is on, CY2890 will emulate 8 bits gray level on 6 bits RGB bus. The users will have a more vivid picture with dither function on. The “Reverse” function is designed for reducing EMI. The key is to lower down the R/G/B transition count. The “dual” function can set the output HCLK to latch the output data at both edges. Set “dual” on can lower down the HCLK frequency to half. With the “Reverse” and “dual” functions, the board level system design can be relaxed. We also have a built-in test pattern generator for users to do a quick final test or aging burning test. The built-in test pattern generator has 24 very popular patterns. It will be free running when MODE = 1, HSYNC = 1 or MODE = 0, DE = 1. You can stop the free-running built-in test pattern at any time. The “flicker” function is used to reduce the flicker phenomenon. For CY2890-AFB and BFA the default panel resolutions are fixed, but they can be changed by external strap resistors. We support 8 different panel resolutions, which can be selected by external strap resistors. Through CY2890, all the necessary horizontal and vertical control signals to TFT-LCD are handled automatically. This includes the polarity invert control. There is a built-in power-on reset circuit in the chip, no need for user to add external reset circuit. If users want to extend the power-on reset, an external capacitor can be added. 2.

Function Description CY2890 can support 8 different kind panel resolutions. To select different panel resolution users have to add an external pull-up resistors at pin39, 40 or 41. At power-on, CY2890 will read in pin39, 40 and 41 as RES[2:0]. In the table below, we mark “x” mean don’t do anything. We mark “pull-down” mean you have to add an external resistor to GND.
