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. Leave floating or tie to GND for best noise immunity. |+| 2 | E1 | input | Device address input bit 1. Hard-wire to VCC or GND to set the slave address bit (E1) used in the I2C device address byte. Internally pulled to GND if left floating. |+| 3 | E2 | input | Device address input bit 2. Hard-wire to VCC or GND to set the slave address bit (E2) used in the I2C device address byte. Internally pulled to GND if left floating. |+| 4 | GND | power_in | Ground reference for the power supply. Connect to system ground. |+| 5 | SDA | bidirectional | I2C serial data. Open-drain bidirectional line used to transfer address and data between master and device; requires an external pull-up resistor to VCC. |+| 6 | SCL | input | I2C serial clock input. Data on SDA is latched on the rising edge and clocked out on the falling edge of SCL. Requires an external pull-up resistor to VCC. |+| 7 | WP | input | Hardware write-protect input. When tied to VCC the entire memory array is write-protected (read-only); when tied to GND writes are enabled. Internally pulled to GND if left floating. |+| 8 | VCC | power_in | Device power supply, 1.7 V to 5.5 V. Decouple with a local bypass capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | MSOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `HG24C04CMM`+- `HG24C04CMM/TR`+- `HG24C04CMMM`+- `HG24C04CMMM/TR`+- `HG24C04CMMN`+- `HG24C04CMMMT`+- `HG24C04CMMMT/TR`+- `HG24C04CMMDQ`+- `HG24C04CMMDQ/TR`+- `HG24C04CMMM5`+- `HG24C04CMMM5/TR`++## CAD (KiCad official)++- Symbol: `HG24C04CMM`+- 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/hg24c04cmm-datasheet.pdf) (25 pp, sha256 `595b3211a0b1550b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
