TM1652 from TM Shenzhen Titan Micro Elec, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply voltage. Typical VDD = 5V; recommended range 3V to 6V (absolute max +7.0V). A 0.1uF (104) decoupling capacitor to GND is required close to the pin.
2 SG1 output Segment driver output 1. Integrated PMOS high-side driver sourcing LED current with 8-step programmable segment drive current (typ. 25mA at VDS=3V, 30mA at VDS=2V at 8/8 setting).
3 SG2 output Segment driver output 2. Integrated PMOS high-side driver, 8-step programmable source current for common-cathode LED segments.
4 SG3 output Segment driver output 3. Integrated PMOS high-side driver, 8-step programmable source current for common-cathode LED segments.
5 SG4 output Segment driver output 4. Integrated PMOS high-side driver, 8-step programmable source current for common-cathode LED segments.
6 SG5 output Segment driver output 5. Integrated PMOS high-side driver, 8-step programmable source current for common-cathode LED segments.
7 SG6 output Segment driver output 6. Integrated PMOS high-side driver, 8-step programmable source current for common-cathode LED segments.
8 SG7 output Segment driver output 7. Integrated PMOS high-side driver, 8-step programmable source current for common-cathode LED segments.
9 SG8/GR6 output Muxed segment/grid output. Acts as SG8 in the 8-seg x 5-digit mode or as GR6 in the 7-seg x 6-digit mode; role is chosen by the display-mode configuration command over the SDA interface. Do NOT connect to both a segment and a common on the same digit array or the display will misbehave.
10 GND power_in Ground / power return, 0V reference for VDD and all signals.
11 GR5 output Grid (digit-common) driver output 5. Integrated NMOS low-side driver sinking LED current with 16-step programmable duty cycle (typ. 140mA sink at VDS=0.3V, absolute max 170mA at 0.3V).
12 GR4 output Grid (digit-common) driver output 4. Integrated NMOS low-side sink driver with 16-step programmable duty cycle for common-cathode digit selection.
13 GR3 output Grid (digit-common) driver output 3. Integrated NMOS low-side sink driver with 16-step programmable duty cycle for common-cathode digit selection.
14 GR2 output Grid (digit-common) driver output 2. Integrated NMOS low-side sink driver with 16-step programmable duty cycle for common-cathode digit selection.
15 GR1 output Grid (digit-common) driver output 1. Integrated NMOS low-side sink driver with 16-step programmable duty cycle for common-cathode digit selection.
16 SDA input Serial data input. UART-compatible single-wire receive line at 19200bps (bit width 47-57us); accepts commands and display data from an MCU TX pin. VIH >= 0.7VDD, VIL <= 0.3VDD; input current +/-1uA. Compatible with 3.3V or 5V MCU drive.

Manufacturer TM Shenzhen Titan Micro Elec
Package SOIC-16

CAD (KiCad official)

  • Symbol: TM1652
  • Footprint: Package_SO:SOIC-16_3.9x9.9mm_P1.27mm
  • 3D model: SOIC-16 (KiCad packages3D, STEP)
  • 3D model files: tm1652-etched.step / tm1652-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tm1652.step / tm1652.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tm1652.step 217 KB You want the bare part, or you mark your own boards.
tm1652-etched.step 1.8 MB You want the part with TM1652 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 454 faces against 267 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
