4 / 10 page Block Diagram Pin Functions No. 3586-4/10 LC7574NE, 7574NW Pin No. Pin I/O Function Handling when unused 4 VFL — Driver block power supply. A voltage of between 8.0 and 18.0 V must be supplied. — 1 VDD — Logic block power supply. A voltage of between 4.5 and 5.5 V must be supplied. — 46 VSS — Ground. Must be connected to the system ground. — 48 OSC I/O Oscillator connection. An oscillator circuit is formed by connecting an external resistor and capacitor to this pin. VDD Display off control input 47 BLK I BLK = low (VSS): Display off (G1 and G2 = low) GND BLK = high (VDD): Display on Note that serial data can be transferred while the display is turned off. 44 CL Serial data transfer inputs. These pins must be CL: synchronization clock 43 DI I connected to the system controller. DI: transfer data GND 42 CE CE: chip enable When the analog dimmer is selected, the analog voltage applied to this pin controls the duty of the G1 and G2 digit output pins. Since a 6-bit A/D converter is applied to this analog voltage and that result is 45 DIM I input to a decoder that provides a built-in dimmer curve, the relationship between the analog voltage GND and the duty can be specified as a mask program. Note that 63/96 · VDD is the full-scale level for the 6-bit A/D converter. 2, 3 G1, G2 O Digit outputs. The frame frequency fO is (fOSC/4096) Hz Open 41 to 5 S1 to S37 O Segment outputs for displaying the display data transferred by serial data input. Open |
