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 | A0 | unconnected | On the AT24C16, the device address input A0 is a No Connect and may be tied to GND. It is not used for hardware device addressing on the 16K variant (whole address space is used for memory page selection). |+| 2 | A1 | unconnected | On the AT24C16, the device address input A1 is a No Connect and may be tied to GND. Not used for hardware device addressing on the 16K variant. |+| 3 | A2 | unconnected | On the AT24C16, the device address input A2 is a No Connect and may be tied to GND. Not used for hardware device addressing on the 16K variant. |+| 4 | GND | power_in | Ground reference for the device (0 V). |+| 5 | SDA | bidirectional | Two-wire serial data line. Open-drain, bi-directional; must be tied to VCC through an external pull-up resistor. May be wire-ORed with any number of other open-drain / open-collector devices on the same bus. |+| 6 | SCL | input | Two-wire serial clock input. Positive edge clocks data into the EEPROM; negative edge clocks data out. Compatible with 1 MHz (at 5V) and 400 kHz (at 1.8/2.5/2.7V) bus speeds. |+| 7 | WP | input | Hardware Write Protect input. Tie to GND for normal read/write operations. Tie to VCC to enable write protection of the full 16K array (see Table 2). |+| 8 | VCC | power_in | Positive supply voltage input. Operating range 1.7 V to 5.5 V. Decouple to GND with a local bypass capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HANSCHIP semiconductor |+| Package | MSOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `AT24C16DGKRG`+- `AT24C16DGKRGDRG`+- `AT24C16DGKRGPG`+- `AT24C16DGKRGDBVRG`++## CAD (KiCad official)++- Symbol: `AT24C16DGKRG`+- 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:** [HANSCHIP semiconductor datasheet](docs/at24c16dgkrg-datasheet.pdf) (17 pp, sha256 `b84e9e47db0cdee0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
