LED Control IC

W2RG012RN

■ Control Waveform

The matrix is controlled by switching between ON and OFF of drive output terminals (OUT0R - 7B) and switch output terminals (OUTS0 - 7).

Note: XTI = 8.192 MHz = 122.07 ns. The indication of duration in these figures is for 16x8 configuration. The duration is twice the indicated value

for 24x4 configuration; 4 times for 24x2 configuration; and 8 times for 24x1 configuration.
