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 | NC | unconnected | No internal connection. May be left floating or tied to GND. |+| 2 | NC | unconnected | No internal connection. May be left floating or tied to GND. |+| 3 | E2 | input | Device address input. Hard-wired to VCC or GND to set the E2 address bit for bus multi-drop (up to 8 devices with two device-type identifiers). Internally pulled down to GND when left floating. |+| 4 | GND | power_in | Ground reference for the power supply. Connect to system ground. |+| 5 | SDA | bidirectional | Serial data. Open-drain bidirectional I/O for the 2-wire I2C interface; requires an external pull-up to VCC. Data is transferred MSB-first, latched on rising SCL and driven on falling SCL. |+| 6 | SCL | input | Serial clock input for the 2-wire I2C interface. Supports up to 400 kHz standard and 1 MHz high-speed transfer rates; requires an external pull-up to VCC. |+| 7 | WP | input | Hardware write-protect input. Tie to VCC to make the whole memory array read-only; tie to GND to enable writes. Internally pulled down to GND when left floating. When driven high, only the device address and word address bytes are ACKed; data bytes are NACKed. |+| 8 | VCC | power_in | Device power supply, 1.7 V to 5.5 V. Operation outside this range may produce spurious results and must be avoided. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | MSOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `HG24C08CMM`+- `HG24C08CMM/TR`+- `HG24C08CMMHG24C08CN`+- `HG24C08CMMHG24C08CM/TR`+- `HG24C08CMMHG24C08CMT/TR`+- `HG24C08CMMHG24C08CDQ/TR`+- `HG24C08CMMHG24C08CM5/TR`++## CAD (KiCad official)++- Symbol: `HG24C08CMM`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/hg24c08cmm-datasheet.pdf) (25 pp, sha256 `90e20e751b466cc6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
