1 Introduction
1.1 Features
The TLC6984 is a highly integrated, common cathode matrix LED display driver with 48 constant current
sources and 16 scanning FETs. One TLC6984 is capable of driving 16 × 16 RGB LED pixels, while stacking
two TLC6984s can drive 32 × 32 RGB LED pixels, three TLC6984s are capable of driving 48 × 48 RGB LED
pixels, and stacking four TLC6984s can drive 64 × 64 RGB LED pixels. To achieve low power consumption, the
device supports separated power supplies for the red, green, and blue LEDs by its common cathode structure.
Furthermore, the operation power of the TLC6984 is significantly reduced by ultra-low operation voltage range
(Vcc down to 2.5 V) and ultra-low operation current (Icc down to 3.6 mA).
The TLC6984 implements a high speed, dual-edge transmission interface to support high device count daisy-
chained and high refresh rate while minimizing electrical-magnetic interference (EMI). The device supports up
to 25-MHz SCLK (external) and up to 160-MHz GCLK (internal). Meanwhile, the device integrates enhanced
circuits and intelligent algorithms to solve the various display challenges in Narrow Pixel Pitch (NPP) LED
display applications and mini and micro-LED products. The display challenges are dim at the fist scan line, upper
and downside ghosting, non-uniformity in low gray scale, coupling, caterpillar caused by open or short LEDs,
which make the TLC6984 a perfect choice in such applications.
The TLC6984 also implements LED open and weak, short and short detections and removals during operations
and can also report this information out to the accompanying digital processor.
1.2 Applications
The TLC6984 EVM can be used as a basic function evaluation module for the following applications:
• Narrow Pixel Pitch (NPP) LED display
• Mini and micro-LED products

3 Test Setup
Table 3-1 shows the typical parameters for TLC6984 EVM.
Table 3-1. TLC6984EVM Parameters
Parameter Value
VCC device supply voltage 2.5–5.5 V
VLEDR/G/B supply voltage 2.5–5.5 V
ICH constant output source current 0.2–20 mA
The TLC6984EVM can be setup and tested by following these steps:
1. USB power supply
a. Download the code to MSP430F5529 LaunchPad with TI CCS software.
b. Connect boosterpack connectors (J1, J2 on EVM board) with the MSP430F5529 LaunchPad. Figure 3-1
shows the connection method.
c. Disconnect J4 jumpers (5 V/ 3V3) block, connect J5 jumper, and connect J3 with the mini-USB cable
(the same cable with the MSP430F5529 LaunchPad).
2. External power supply
a. Download the code to MSP430F5529 LaunchPad with TI CCS software.
b. Connect boosterpack connectors (J1, J2 on EVM board) with the MSP430F5529 LaunchPad. Figure 3-1
shows the connection method.
c. Disconnect J4 jumpers (5 V/ 3V3), connect J5 jumper, and connect TP1/TP2 to 5V/GND power source.
d. Power on 5 V/GND power supply.
