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 | E0 | input | Slave address input bit 0. Hardware-addressed; internally pulled down to Vss if left floating. Allows up to 8 devices to share the I2C bus. |+| 2 | E1 | input | Slave address input bit 1. Hardware-addressed; internally pulled down to Vss if left floating. |+| 3 | E2 | input | Slave address input bit 2. Hardware-addressed; internally pulled down to Vss if left floating. |+| 4 | Vss | power_in | Ground reference for the Vcc supply. |+| 5 | SDA | bidirectional | Bidirectional serial data line for the I2C bus. Open-drain output; requires an external pull-up resistor and may be wire-OR'ed with other open-drain devices. |+| 6 | SCL | input | I2C serial clock input. Positive-edge clocks data into the device; negative-edge clocks data out. Supports 400 kHz / 1 MHz operation. |+| 7 | WCB | input | Write Control, active-low enable. Tie to Vcc to inhibit all memory write operations; tie to Vss to allow normal writes. Internally pulled down to Vss if left floating. |+| 8 | VCC | power_in | Supply voltage. Operating range 1.7 V to 5.5 V. Read current ~0.2 mA and write current ~0.8 mA typical at 400 kHz. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | DIP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT24C32NN`+- `AT24C32NM/TR`+- `AT24C32NMM/TR`+- `AT24C32NMT/TR`+- `AT24C32NDQ3/TR`+- `AT24C32NM5/TR`++## CAD (KiCad official)++- Symbol: `AT24C32N`+- 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/at24c32n-datasheet.pdf) (20 pp, sha256 `7e4214ab634175eb`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
