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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | TSOT-23-5L |+| Category | Memory |+| Pins | 5 |++## Ordering variants++- `BL24C04F-RRRCRRRC`+- `BL24C04F-RRRCRRRS`+- `BL24C04F-RRRCTCRC`+- `BL24C04F-RRRCTCRS`+- `BL24C04F-RRRCDARC`+- `BL24C04F-RRRCDARS`+- `BL24C04F-RRRCPARC`+- `BL24C04F-RRRCPARS`+- `BL24C04F-RRRCSFRC`+- `BL24C04F-RRRCSFRS`+- `BL24C04F-RRRCNTRC`+- `BL24C04F-RRRCNTRS`++## CAD (KiCad official)++- Symbol: `BL24C04F-RRRC`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: TSOT-23-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/bl24c04f-rrrc-datasheet.pdf) (19 pp, sha256 `5bddea927a0b005c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
