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. Not internally bonded; leave floating or optionally tie to Vss. |+| 2 | NC | unconnected | No connect. Not internally bonded; leave floating or optionally tie to Vss. |+| 3 | E2 | input | Slave address select input for AT24C08 (bit E2 of the I2C device address, allowing up to 2 devices on one bus). Internally pulled down to Vss if left floating, forcing the corresponding address bit to 0. Logic levels: VIL <= 0.3*VCC, VIH >= 0.7*VCC. |+| 4 | Vss | power_in | Ground reference for VCC supply. |+| 5 | SDA | bidirectional | I2C serial data input/output. Open-drain; requires an external pull-up resistor to VCC (typical 1.3 kOhm at 2.5-5.5 V, 10 kOhm at 1.7 V). Wire-OR compatible with other open-drain devices; VOL <= 0.4 V at IOL = 2.1 mA (VCC = 3.0 V). |+| 6 | SCL | input | I2C serial clock input. Data clocked in on positive edge and out on negative edge. Supports up to 400 kHz (Fast Mode) or 1 MHz (Fast Mode Plus) across 1.7-5.5 V. Schmitt-triggered with noise-suppression filter (tI = 100 ns at 400 kHz). |+| 7 | WCB | input | Write control (active-low enable). Tie to Vss (or leave floating - internally pulled down to Vss) to allow normal write operations; tie to VCC to inhibit all write operations to the memory array. Provides hardware write protection. |+| 8 | VCC | power_in | Supply voltage input, 1.7 V to 5.5 V. Typical standby current 0.5-1.0 uA; read current 0.2 mA and write current 0.8 mA typical at 400 kHz. Absolute maximum 6.5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | DIP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT24C08NN`+- `AT24C08NM/TR`+- `AT24C08NMT/TR`+- `AT24C08NMM/TR`+- `AT24C08NDQ3/TR`+- `AT24C08NDQ2/TR`+- `AT24C08NM5/TR`++## CAD (KiCad official)++- Symbol: `AT24C08N`+- Footprint: `Package_DIP:DIP-8_W7.62mm`+- 3D model: DIP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/at24c08n-datasheet.pdf) (None pp, sha256 `3e86ae75d43fb087`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
