at24c16d.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

AT24C16D

IDCHIP · EEPROM · SOP-8

AT24C16D from IDCHIP, in a SOP-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. Not internally bonded; leave floating or tie as convenient. On the AT24C16D the three lower address pins A0/A1/A2 are unused because the device's 11-bit word address consumes the p0/p1/p2 bits that would otherwise be device-select bits.
2 NC unconnected No connect. Not internally bonded; leave floating or tie as convenient.
3 NC unconnected No connect. Not internally bonded; leave floating or tie as convenient.
4 GND power_in Ground / power negative return. Common reference for VCC and the I2C bus.
5 SDA bidirectional I2C serial data line. Open-drain bidirectional data pin; requires an external pull-up to VCC (typ. 10 kΩ). Carries address and data during read/write transactions, and drives ACK/NACK on the 9th clock.
6 SCL input I2C serial clock input driven by the bus master. Data on SDA is sampled on the rising edge and shifted on the falling edge. Maximum frequency 400 kHz at 1.8-2.7 V, 1 MHz at 5 V. Requires an external pull-up (typ. 10 kΩ).
7 WP input Hardware write-protect input. When tied to VCC, write operations to the entire array are inhibited; when tied to GND (or left low), normal write operations are permitted. Read operations are unaffected.
8 VCC power_in Positive supply voltage, 1.8 V to 5.5 V (absolute max 5.5 V). Recommended decoupling with a 1 µF capacitor to GND close to the pin. Standby current <1 µA, active read ~0.5 mA, active write ~2 mA.

Ordering variants

  • AT24C16D

CAD (KiCad official)

  • Symbol: AT24C16D
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: at24c16d-etched.step / at24c16d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c16d.step / at24c16d.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
at24c16d.step 122 KB You want the bare part, or you mark your own boards.
at24c16d-etched.step 1.6 MB You want the part with AT24C16D already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 403 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.
