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 | Serial Clock input. Provides the clock reference for the 2-wire I2C-compatible bus (up to 400 kHz Fast mode or 1 MHz High-speed mode). Command/data on SDA is latched on the rising edge of SCL, output data is clocked out on the falling edge. Open-drain bus line requiring an external pull-up to VCC. Schmitt trigger with integrated spike-suppression filter. |+| 2 | GND | power_in | Ground reference for the power supply. Must be connected to the system ground. |+| 3 | SDA | bidirectional | Serial Data. Open-drain bidirectional I/O used to serially transfer command, address, and data bytes to/from the device (MSB first). Requires an external pull-up resistor to VCC (see Figure 21 for R_pull vs bus capacitance). Schmitt trigger with integrated spike-suppression filter. |+| 4 | VCC | power_in | Device power supply, 1.7 V to 5.5 V. Absolute-max -0.5 V to +6.0 V. Typical currents: 0.5 mA read @ 1 MHz, 1 mA write @ 400 kHz, 1 uA standby (max). |+| 5 | WP | input | Write Protection input. Tie to VCC to write-protect the entire memory array and Identification Page (device becomes read-only); tie to GND to enable writes. Internally pulled down to GND if left floating. When high, address bytes are ACKed but data bytes are NACKed. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor |+| Package | SOT-23-5 |+| Category | Memory |+| Pins | 5 |++## Ordering variants++- `HX24LC04BDBVRG`+- `HX24LC04BDBVRGPG`+- `HX24LC04BDBVRGDRG`+- `HX24LC04BDBVRGDRG4`+- `HX24LC04BDBVRGDGKRG`+- `HX24LC04BDBVRGPWRG`+- `HX24LC04BDBVRGDQRG`++## CAD (KiCad official)++- Symbol: `HX24LC04BDBVRG`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HANSCHIP semiconductor datasheet](docs/hx24lc04bdbvrg-datasheet.pdf) (None pp, sha256 `facb7da4679f13a4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
