Pin Number Symbol I/O Function
P Po we er r S Su up pp pl ly y9 VDD PP Po we er r S Su up pp pl ly y f fo or r L Lo og gi ic c. This pin serves as a voltage supply terminal for the logic circuitry and must be connected to an external power source.
8 VSS PG Gr ro ou un nd d o of f L Lo og gi ic c C Ci ir rc cu ui it t. This pin functions as a ground terminal, providing a reference point for the logic circuits. It’s crucial to connect this pin to an external ground connection.
28 VCC PP Po o we er r S Su up pp pl ly y f fo or r OE EL L P Pa an ne el l. This pin delivers the positive voltage required for the Output Enable (OE) and Panel control signals. A capacitor should be connected between this pin and VSS when using a converter, and it must be externally powered when the converter is not in use.
29 VLSS PG Gr ro ou un nd d o of f A An na al lo og g C Ci ir rc cu ui it t. Designated as an analog ground pin, this terminal should be connected to VSS externally for optimal circuit performance.
26 IREF IC Cu ur rr re en nt t R Re ef fe er re en nc ce e f fo or r B Br ri ig gh ht tn ne es ss s s A Ad dj ju us st t me en nt t. This segment current reference pin requires a resistor connection to VSS, with a maximum current setting of 12.5μA.
27 VCOMH OV Vo ol lt ta ag ge e Ou ut tp pu ut t Hi ig hh h L Le ev ve el l f fo or r C C O M S Si ig gn na al l. This input pin provides the high-level voltage necessary for the COM signals; a capacitor should be connected between this pin and VSS to ensure stable operation.
6 VDDB PP Po o we er r S Su up pp pl ly y f fo or r DC C/ / DC C C Co on nv ve er rt te er r Ci ir rc cu ui it t. This is the power supply dedicated to powering the internal buffer within the DC/DC voltage converter circuit; it must be externally powered when in operation and connected to VDD when inactive.
4 / 52 / 3C1P / C1NC2P / C2NIP Po os si it ti iv ve e T Te er r mi in na al l o of f t th he e F Fl ly yi in ng g I In nv ve er rt ti in ng g C Ca ap pa ac ci it to or r . These terminals are essential for charge-pump capacitors, which must be floated when the converter is not operating under load..
I In nt te er rf fa ac ce e101112BS0BS1BS2IC Co o m mu un ni ic ca at ti in ng g P Pr ro ot to oc co ol l S Se el le ec ct t . These pins serve as MCU interface selection inputs, supporting various communication protocols including SPI (both 3-wire and 4-wire), parallel communication (8-bit and 18-bit), and I2C mode with SA0 selection..
17 E/RD# IR Re ea ad d/ / Wr ri it te e E En na ab bl le e o or r R Re ea ad d . This input pin enables read/write operations when interfacing with microprocessors like 68XX series (as Enable signal) or 80XX series (as Read signal). Serial or I2C modes require connection to VSS..
18~25 D0~D7 I/OHo os st t Da at ta a I In np pu ut t/ / Ou ut tp pu ut t B Bu us s . These eight-bit bidirectional data lines provide connectivity between the microcontroller’s data bus during serial communication; D1 functions as serial data input (SDIN) and SCLK during serial mode, while D0 & D1 serve as SDA out & SDA in during I2C mode.. Unused pins should be tied to VSS except for D2 during serial operation..
7 N.C.- Reserved Pin: The N.C., or “No Connection,” pins are designated for flexible design compatibility; they are reserved for future expansion options.. The supporting pins are also reserved, offering ESD protection capabilities by connecting them externally to ground (pin 30).
