UPD16311 Description
Inputs serial data at rising edge of shift clock, starting from lower bit. Outputs serial data at falling edge of shift clock, starting from lower bit. This is N-ch open-drain output pin.
UPD16311 Key Features
- Many display modes (12-segment & 16-digit to 20-segment & 8-digit)
- Key scanning (12 4 matrices)
- Dimming circuit (eight steps)
- High-voltage output (VDD 35 V max)
- LED ports (5 chs., 20 mA max)
- General-purpose input port (4 bits)
- No external resistor necessary for driver outputs (P-ch open-drain + pull-down resistor output)
- Serial interface (CLK, STB, DIN, DOUT)
