The LP5890 is a highly integrated, common cathode matrix LED display driver with 48 constant current sources and 16 scanning FETs. One LP5890 is capable of driving 16 × 16 RGB LED pixels, while stacking two LP5890 can drive 32 × 32 RGB LED pixels, which simplifies component placement and control. With the common cathode structure, the device supports separated power supplies for the red, green, and blue LEDs to achieve low power consumption. - Page 3 The LED side of the LP5890EVM board is shown in Figure 2-2.

- Page 7 2.2.3 Hardware Setup for Dual Cascaded Devices The LP5890EVM can be cascaded in a daisy chain. In such case, each LP5890 works in the independent mode (compared to the stackable mode). The host TMS320F280039C LaunchPad sends the serial data to the first LP5890 through the 40-pin BoosterPack Header.
