4 / 13 page Block Diagram No. 5606-4/13 LC75725E Pin Functions Pin Pin No. Function I/O Handling when unused VFL 1, 13 Driver block power supply connection. (Both pins must be connected.) — — VDD 60 Logic block power supply connection. Provide a voltage between 4.5 and 5.5 V. — — VSS 57 Power supply connection. Connect to the ground. — — OSCI 59 Oscillator connection. An oscillator circuit is formed by connecting an external resistor I GND OSCO 58 and capacitor to these pins. O OPEN Display off control input. BLK 61 BLK = Low (VSS) ... Display off. (S1 to S43 and G1 to G11 at VFL level.) I GND BLK = High (VDD) ... Display on. Note that serial data can be transferred while the display is turned off. CL 63 DI 64 I GND CE 62 G1 to G11 2 to 12 Digit outputs. These pins are P-channel open drain outputs with pull-down resistors. O OPEN S1 to S43 56 to 14 Segment outputs for displaying the display data transferred by serial data input. These pins O OPEN are P-channel open drain outputs with pull-down resistors. Serial data transfer inputs. These pins must be connected to the system microcontroller. CL: Synchronization clock DI: Transfer data CE: Chip enable |
