BU9799KV-E2

ROHM Semicon · LCD Drivers · LQFP-64(10x10)

BU9799KV-E2 from ROHM Semicon, in a LQFP-64(10x10). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VLCD power_in Power supply for LCD driving, 2.5 V to 5.5 V recommended operating range with VSS = 0 V.
2 VDD power_in Power supply, 2.5 V to 5.5 V recommended operating range with VSS = 0 V.
3 VSS power_in Ground reference (GND) for the device; the voltage on this pin must be the lowest of all pins.
4 OSCIN input External clock input; must be connected to VSS when the internal oscillation circuit is used.
5 TEST3 input Test input for ROHM use only; must be connected to VSS.
6 SCL input Serial data transfer clock input of the 2-wire serial interface.
7 SDA input Serial data input of the 2-wire serial interface.
8 INHb input Input terminal for turning the display on (H) or off (L).
9 TEST1 input Test input for ROHM use only; L enables the POR circuit and H disables it, see Cautions in Power ON/OFF.
10 TEST2 input Test input for ROHM use only; must be connected to VSS.
