TM1722 from TM Shenzhen Titan Micro Elec, in a SOP-24-300mil. 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 | VDD | power_in | Supply voltage positive, connect to system power supply (5V nominal). |
| 2 | DIO | bidirectional | Bidirectional serial data line that inputs/outputs serial data on clock rising edge starting from LSB. |
| 3 | CLK | input | Serial clock input line for reading serial data on rising edge. |
| 4 | STB | input | Chip select/strobe input that initializes serial interface on falling edge; first byte after falling edge is instruction. |
| 5 | GND | power_in | System ground, connect to system negative. |
| 6 | SEG28 | output | LCD segment 28 drive output. |
| 7 | SEG29 | output | LCD segment 29 drive output. |
| 8 | SEG30 | output | LCD segment 30 drive output. |
| 9 | SEG31 | output | LCD segment 31 drive output. |
| 10 | PWM0/SEG20 | output | Configurable output port for LCD segment 20 drive or PWM0 output with 64-level PWM for backlight control. |
| 11 | SEG22/PWM2 | output | Configurable output port for LCD segment 22 drive or PWM2 output with 64-level PWM for backlight control. |
| 12 | PWM3/SEG23 | output | Configurable output port for LCD segment 23 drive or PWM3 output with 64-level PWM for backlight control. |
| 13 | SEG12 | output | LCD segment 12 drive output. |
| 14 | SEG13 | output | LCD segment 13 drive output. |
| 15 | SEG14 | output | LCD segment 14 drive output. |

Package_SO:SOP-24_7.5x15.4mm_P1.27mm - 3D model: SOP-24-300mil, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 2.65 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
