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-triggered, filtered. Max clock 400 kHz at VCC 1.7-2.5 V, 1 MHz at VCC 2.5-5.5 V. VIH >= 0.7 x VCC, VIL <= 0.3 x VCC. Typical input capacitance 6 pF. |+| 2 | GND | power_in | Device ground reference (0 V). |+| 3 | SDA | bidirectional | I2C bidirectional serial data. Open-drain output; requires an external pull-up to VCC and may be wire-OR'd with other open-drain devices. VOL <= 0.4 V at IOL = 3.0 mA (VCC = 5 V). Typical I/O capacitance 8 pF. |+| 4 | VCC | power_in | Positive supply voltage. Operating range 1.7 V to 5.5 V (400 kHz) or 2.5 V to 5.5 V (1 MHz). ICC ~0.14 mA read / 0.28 mA write at 400 kHz, standby ~0.03 uA. Absolute maximum 6.5 V. |+| 5 | WP | input | Hardware Write Protect input. Tie to GND for normal read/write operation; tie to VCC to write-protect the full array. Schmitt-triggered logic input. Do not leave floating. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | TSOT23-5L |+| Category | Memory |+| Pins | 5 |++## Ordering variants++- `BL24C04AE0-RRRC`+- `BL24C04AE0-RRRCRRRS`+- `BL24C04AE0-RRRCTCRC`+- `BL24C04AE0-RRRCTCRS`+- `BL24C04AE0-RRRCPARC`+- `BL24C04AE0-RRRCPARS`+- `BL24C04AE0-RRRCSFRC`+- `BL24C04AE0-RRRCSFRS`+- `BL24C04AE0-RRRCDARC`+- `BL24C04AE0-RRRCDARS`+- `BL24C04AE0-RRRCNTRC`+- `BL24C04AE0-RRRCNTRS`++## CAD (KiCad official)++- Symbol: `BL24C04AE0-RRRC`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: TSOT23-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/bl24c04ae0-rrrc-datasheet.pdf) (24 pp, sha256 `07de7e3648177ef4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
