AT24C32E-STUM-T

Microchip Tech · EEPROM · SOT-23-5

AT24C32E-STUM-T from Microchip Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

Pinout

Pin Name Type Function
1 SCL input Serial clock input; command and input data on SDA are latched on its rising edge, output data is clocked out on its falling edge, and it must be forced high when the bus is idle or pulled high with an external pull-up resistor.
2 GND power_in Ground reference for the power supply, which should be connected to the system ground.
3 SDA bidirectional Open-drain serial data input/output that must be pulled high with an external pull-up resistor not exceeding 10 kΩ and may be wire-ORed with other open-drain devices on the bus.
4 VCC power_in Device power supply pin supplying 1.7 V to 3.6 V; operation at invalid VCC voltages may produce spurious results and should not be attempted.
5 WP input Write-protect input: connecting it to GND allows normal write operations, connecting it to VCC inhibits writes to the full array, and it is internally pulled down to GND if left floating (pull-up of 10 kΩ or less recommended).

CAD (land: KiCad; 3D: generated from the datasheet)

  • Symbol: AT24C32E-STUM-T
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5, generated on the KiCad land (body 1.6 x 2.9 mm, terminals on the pads, 1.1 mm tall, datasheet A, max). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: at24c32e-stum-t-etched.step / at24c32e-stum-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c32e-stum-t.step / at24c32e-stum-t.glb are the bare package body.
