Leave floating or tie to VSS. |+| 2 | NC | unconnected | No internal connection. Leave floating or tie to VSS. |+| 3 | NC | unconnected | No internal connection. Leave floating or tie to VSS. |+| 4 | VSS | power_in | Ground reference for the device. Connect to system ground. |+| 5 | SDA | bidirectional | I2C serial data line (open-drain). Requires an external pull-up resistor (typ. 4.7kΩ per the typical operating circuit). Compatible with 2-wire (24-Series) EEPROM pinout. |+| 6 | SCL | input | I2C serial clock input, up to 1.0 MHz. Requires an external pull-up resistor (typ. 4.7kΩ). |+| 7 | NC | unconnected | No internal connection. Leave floating or tie to VSS. |+| 8 | VCC | power_in | Main supply, 2.0V to 5.5V operating range. Bypass to VSS with a 0.1µF ceramic capacitor as shown in the typical operating circuit. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | WEIKAI |+| Package | SOT23-5 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `DX81C04-C`++## CAD (KiCad official)++- Symbol: `DX81C04-C`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [WEIKAI datasheet](docs/dx81c04-c-datasheet.pdf) (25 pp, sha256 `5396fdb964b053cd`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
