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 connect. Leave floating or tie to any convenient net; no internal connection on the DIP-8/SOP-8/MSOP-8/TSSOP-8 variants. |+| 2 | NC | unconnected | No connect. Leave floating or tie to any convenient net; no internal connection on the DIP-8/SOP-8/MSOP-8/TSSOP-8 variants. |+| 3 | E2 | input | Device address input (A11 slave address bit). Tie to VCC or GND to select one of two device addresses on a shared 2-wire bus (used for compatibility with legacy 2-wire EEPROMs). Internally pulled down to GND if left floating. |+| 4 | GND | power_in | Ground reference for the power supply. Connect to the system ground. |+| 5 | SDA | bidirectional | I2C serial data. Open-drain bidirectional I/O; requires an external pull-up resistor to VCC. Data is latched into the device on the rising edge of SCL and driven out on the falling edge of SCL. |+| 6 | SCL | input | I2C serial clock input. Master-driven clock used to synchronize data transfers on SDA; supports up to 400 kHz standard-mode and 1 MHz high-speed operation. |+| 7 | WP | input | Hardware write-protect 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. |+| 8 | VCC | power_in | Device power supply, 1.7 V to 5.5 V. Bypass to GND with a decoupling capacitor close to the pin. Operating current is 0.5 mA (write) / 0.2 mA (read); standby is 1 μA maximum. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | MSOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT24C08CMM`+- `AT24C08CMM/TR`+- `AT24C08CMMN`+- `AT24C08CMMM/TR`+- `AT24C08CMMMT/TR`+- `AT24C08CMMDQ/TR`+- `AT24C08CMMM5/TR`++## CAD (KiCad official)++- Symbol: `AT24C08CMM`+- 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/at24c08cmm-datasheet.pdf) (25 pp, sha256 `e1c182cb482476f4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
