On the 8K variant this device-address input is unused (the corresponding address bit is used internally for page addressing); tie to GND for compatibility. |+| 2 | A1 | unconnected | No connect on the HG24LC08. On the 8K variant this device-address input is unused (the corresponding address bit is used internally for page addressing); tie to GND for compatibility. |+| 3 | A2 | input | Device-address input for the HG24LC08. Sets the hard-wired A2 bit compared against the device-address byte; up to two 8K devices per bus. Schmitt-triggered CMOS input. |+| 4 | GND | power_in | Ground reference for the device. |+| 5 | SDA | bidirectional | Bidirectional I2C serial data line, open-drain. Requires external pull-up to VCC. Compatible with 1 MHz (5 V) and 400 kHz (1.8/2.5/2.7 V) bus rates. |+| 6 | SCL | input | I2C serial clock input. Positive edge clocks data into the EEPROM, negative edge clocks data out. Schmitt-triggered. |+| 7 | WP | input | Write-protect input. Tie to GND for normal read/write; tie to VCC to write-protect the entire 8K array. Schmitt-triggered. |+| 8 | VCC | power_in | Supply voltage input. Operating range 1.7 V to 5.5 V. Recommend a 100 nF decoupling capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `HG24LC08MM`+- `HG24LC08MM/TR`+- `HG24LC08MN`+- `HG24LC08MMM`+- `HG24LC08MMM/TR`+- `HG24LC08MM5`+- `HG24LC08MM5/TR`++## CAD (KiCad official)++- Symbol: `HG24LC08M`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/hg24lc08m-datasheet.pdf) (15 pp, sha256 `9d218d780eb41d4d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
