at24c16c-sshm-t.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

AT24C16C-SSHM-T

Microchip · EEPROM · SOIC-8

AT24C16C-SSHM-T from Microchip, in a SOIC-8. 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 NC unconnected No connect. The AT24C16C does not use device address pins; this pin is not internally bonded.
2 NC unconnected No connect. The AT24C16C does not use device address pins; this pin is not internally bonded.
3 NC unconnected No connect. The AT24C16C does not use device address pins; this pin is not internally bonded.
4 GND power_in Ground reference (0V) for the device.
5 SDA bidirectional I2C serial data. Bidirectional open-drain line for serial data transfer; may be wire-ORed with other open-drain / open-collector devices. Requires an external pull-up resistor to VCC.
6 SCL input I2C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Schmitt-trigger filtered input. Requires an external pull-up resistor to VCC.
7 WP input Write Protect. Tie to GND for normal read/write operation. Tie to VCC to enable hardware write protection of the full array (per Table 4-1).
8 VCC power_in Power supply input. Operating range 1.7V to 5.5V. Typical supply current 0.4mA read / 2.0mA write at VCC=5V, 100kHz. Standby current 1.0uA (1.7V) / 6.0uA (5.5V) max.

CAD (KiCad official)

  • Symbol: AT24C16C-SSHM-T
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: at24c16c-sshm-t-etched.step / at24c16c-sshm-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c16c-sshm-t.step / at24c16c-sshm-t.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
at24c16c-sshm-t.step 122 KB You want the bare part, or you mark your own boards.
at24c16c-sshm-t-etched.step 2.5 MB You want the part with AT24C16C-SSHM-T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 625 faces against 147 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: Microchip datasheet (23 pp, sha256 72c6f7b17a742444, retrieved 2026-08-17, tier: manufacturer)
  • 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).
