AT24C16M5

HGSEMI · EEPROM · SOT-23-5

AT24C16M5 from HGSEMI, in a SOT-23-5. 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 SCL input I2C serial clock input. Positive-edge clocks data in; negative-edge clocks data out. Schmitt-triggered, noise-filtered input.
2 Vss power_in Ground reference for the VCC supply voltage.
3 SDA bidirectional I2C bidirectional serial data. Open-drain output; requires an external pull-up to VCC. May be wire-OR'd with other open-drain devices. VOL = 0.4 V max at IOL = 2.1 mA (VCC = 3.0 V).
4 VCC power_in Supply voltage input, 1.7 V to 5.5 V. Absolute maximum 6.5 V. Standby current ~1 uA at 5.5 V; read current ~0.2 mA at 400 kHz.
5 WCB input Write Control input, active low. Tie to VCC to inhibit all write operations to the memory array; tie to Vss (or leave floating, internally pulled to Vss) to allow normal writes.

CAD (KiCad official)

  • Symbol: AT24C16M5
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: at24c16m5-etched.step / at24c16m5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c16m5.step / at24c16m5.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
at24c16m5.step 85 KB You want the bare part, or you mark your own boards.
at24c16m5-etched.step 1.6 MB You want the part with AT24C16M5 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 402 faces against 102 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: HGSEMI datasheet (21 pp, sha256 3e86ae75d43fb087, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
