BL24C04F-RRRC

BL Shanghai Belling · EEPROM · TSOT-23-5L

BL24C04F-RRRC from BL Shanghai Belling, in a TSOT-23-5L. 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 I2C serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Schmitt-trigger, filtered input for noise suppression; requires an external pull-up resistor (typ. 4.7 kohm to VCC).
2 GND power_in Ground / 0 V reference for the device.
3 SDA bidirectional I2C serial data line. Open-drain, bidirectional; may be wire-ORed with other open-drain/collector devices. Requires an external pull-up resistor to VCC (typ. 4.7 kohm).
4 VCC power_in Positive supply voltage. Single-supply operation across the device's rated VCC range (nominal 1.7-5.5 V for BL24C04F family).
5 WP input Write Protect. When tied to VCC the entire 4K array is write-protected; when tied to GND normal read/write operations are allowed. Do not leave floating.

CAD (KiCad official)

  • Symbol: BL24C04F-RRRC
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: TSOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: bl24c04f-rrrc-etched.step / bl24c04f-rrrc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bl24c04f-rrrc.step / bl24c04f-rrrc.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
bl24c04f-rrrc.step 85 KB You want the bare part, or you mark your own boards.
bl24c04f-rrrc-etched.step 2.3 MB You want the part with BL24C04F-RRRC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 565 faces against 102 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
