CAT24M01WI-GT3

onsemi · EEPROM · SOIC-8

CAT24M01WI-GT3 from onsemi, 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. Pin is not internally bonded and may be left floating or tied to VSS.
2 A1 input Device address input bit 1. Selects one of up to four CAT24M01 devices sharing the same I2C bus (combined with A2). Has an internal pull-down resistor; must match the corresponding bit of the slave address byte.
3 A2 input Device address input bit 2. Selects one of up to four CAT24M01 devices sharing the same I2C bus (combined with A1). Has an internal pull-down resistor; must match the corresponding bit of the slave address byte.
4 VSS power_in Ground reference for the device. Connect to system GND.
5 SDA bidirectional I2C serial data. Open-drain bidirectional data line; input data captured on rising edge of SCL, output data driven on falling edge of SCL. Requires external pull-up to VCC. Input capacitance up to 8 pF.
6 SCL input I2C serial clock input from the bus master. Supports Standard (100 kHz), Fast (400 kHz) and Fast-Plus (1 MHz) modes. Schmitt-trigger input with noise suppression filter.
7 WP input Write Protect. When driven HIGH, inhibits all write operations to the memory array; when LOW (or left floating), writes are enabled via the internal pull-down. Provides hardware write protection for the entire memory.
8 VCC power_in Positive supply, 1.8 V to 5.5 V. Read current up to 1 mA at fSCL = 1 MHz; write current up to 5 mA at VCC = 5.5 V; standby current typ. 2 uA.

CAD (KiCad official)

  • Symbol: CAT24M01WI-GT3
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: cat24m01wi-gt3-etched.step / cat24m01wi-gt3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cat24m01wi-gt3.step / cat24m01wi-gt3.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
cat24m01wi-gt3.step 122 KB You want the bare part, or you mark your own boards.
cat24m01wi-gt3-etched.step 2.3 MB You want the part with CAT24M01WI-GT3 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 595 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: onsemi datasheet (14 pp, sha256 913ea8e62a2ca346, 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).
