Texas Instruments · LCD Drivers · WSON-10-EP(3x3)

LM8342SD from Texas Instruments, in a WSON-10-EP(3x3). 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 OUT output Current sink output adjustable in 128 steps; full scale current range 5 µA to 100 µA
2 AVDD power_in Analog reference voltage input for DAC; operating range 4.5 V to 18 V
3 WPN input Write protect input active low; high level enables EEPROM access; includes internal pull-down resistor
4 WPP output Write protect signal output; logical inverse of WPN input signal
5 GND power_in Ground reference connection
6 VDD power_in Digital supply voltage; operating range 2.25 V to 3.6 V (2.6 V to 3.6 V when AVDD exceeds 13 V)
7 SDA bidirectional I2C compatible serial data line; maximum bus speed 400 kHz; open-drain output requires external pull-up resistor
8 SCL bidirectional I2C compatible serial clock line; maximum bus speed 400 kHz; open-drain output requires external pull-up resistor
9 SCL-S input Switched SCL connection for in-circuit PCB testing; connected to SCL when WPN is high; alternative clock source
10 SET input Maximum output current adjustment pin; connects to external RSET resistor to set full-scale current; typical values 10 kΩ to 45 kΩ
11 DAP passive Exposed pad (from the footprint; not named in the datasheet pin table).
