AT24CS01-STUM-T

Microchip Tech · EEPROM · SOT-23-5

AT24CS01-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, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 SCL input Serial clock input that latches command and input data present on SDA on its rising edge and 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 that should be connected to the system ground.
3 SDA bidirectional Open-drain bidirectional serial data pin that must be pulled high with an external pull-up resistor not exceeding 10 kΩ.
4 VCC power_in Device power supply pin; all packages operate from 1.7V to 5.5V, and 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, while connecting it directly to VCC inhibits all writes to the protected memory.

CAD (KiCad official)

  • Symbol: AT24CS01-STUM-T
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: at24cs01-stum-t-etched.step / at24cs01-stum-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24cs01-stum-t.step / at24cs01-stum-t.glb are the bare package body.
