AT24C16

IDCHIP · EEPROM · SOP-8

AT24C16 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. The AT24C16 consumes all three device-address bits (A0/A1/A2) internally for page selection within the 2Kx8 array, so this pad is left floating on the SOP-8 package.
2 NC unconnected No connect. See pin 1 note; the device-address input is not used on the 16Kbit density.
3 NC unconnected No connect. See pin 1 note; the device-address input is not used on the 16Kbit density.
4 GND power_in Ground reference (0V) for the device (电源负).
5 SDA bidirectional I2C serial data line (串行数据端). Open-drain bidirectional input/output for address, data, and acknowledge bits; requires an external pull-up resistor (typ. 10kΩ) to VCC.
6 SCL input I2C serial clock input (串行时钟端). Clocks data into/out of the device on rising/falling edges; up to 1MHz at VCC=5V, 400kHz at 1.8V/2.5V/2.7V. Requires an external pull-up resistor (typ. 10kΩ) to VCC.
7 WP input Write-protect input (写保护端). When tied high, hardware write protection blocks write operations to the array; when tied low (or left low via pull-down), normal read/write operation is permitted.
8 VCC power_in Positive supply (电源正). Operating range 1.8V to 5.5V (absolute max 5.5V). Recommend a 1μF decoupling capacitor to GND as shown in the typical application circuit.

Ordering variants

  • AT24C16

CAD (KiCad official)

  • Symbol: AT24C16
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: at24c16-etched.step / at24c16-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c16.step / at24c16.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
at24c16.step 122 KB You want the bare part, or you mark your own boards.
at24c16-etched.step 1.4 MB You want the part with AT24C16 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 371 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: IDCHIP datasheet (12 pp, sha256 74187a0319348f68, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
