LED display driver circuit with serial I2C-bus interface using SAA1064

SAA1064 I2C-bus serial LED display driver integrated circuit dynamic driver interface circuit
The dynamic scan showed the SAA1064 is to rely on-chip multiplexer data latch control circuit Kushiro time to master the device without intervention, the use of the most dynamic work function of the potential to play SAA1064, is the most common way of working. The figure number and the data bit LED operating format selected data in the order of the corresponding segment. CEXT for the clock oscillation capacitor, it guarantees the work of the signal with a dynamic drive. MX1, MX2 for display drive signal for Public pole output. Dynamic scan MX1, MX2 timing waveforms shown in Fig.
