CAT24AA16TDI-GT3-TUDI

Tudi · EEPROM · SOT-23-5

CAT24AA16TDI-GT3-TUDI from Tudi, 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 Serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Requires an external pull-up resistor.
2 GND power_in Ground reference (0 V) for the device.
3 SDA bidirectional Bidirectional serial data line. Open-drain output; may be wire-ORed with other open-drain/open-collector devices. Requires an external pull-up resistor.
4 VCC power_in Supply voltage input, 1.7 V to 5.5 V.
5 WP input Write Protect input. Tied to GND for normal read/write operation. Tied to VCC to write-protect the full memory array.

  • 3D model files: cat24aa16tdi-gt3-tudi-etched.step / cat24aa16tdi-gt3-tudi-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cat24aa16tdi-gt3-tudi.step / cat24aa16tdi-gt3-tudi.glb are the bare package body.

Provenance

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

  • Datasheet: Tudi datasheet (18 pp, sha256 07e63c8b6e02f00d, 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).
