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 | SCL | input | I2C serial clock input. Positive-edge clocks data in; negative-edge clocks data out. Schmitt-triggered, noise-filtered input. |+| 2 | Vss | power_in | Ground reference for the VCC supply voltage. |+| 3 | SDA | bidirectional | I2C bidirectional serial data. Open-drain output; requires an external pull-up to VCC. May be wire-OR'd with other open-drain devices. VOL = 0.4 V max at IOL = 2.1 mA (VCC = 3.0 V). |+| 4 | VCC | power_in | Supply voltage input, 1.7 V to 5.5 V. Absolute maximum 6.5 V. Standby current ~1 uA at 5.5 V; read current ~0.2 mA at 400 kHz. |+| 5 | WCB | input | Write Control input, active low. Tie to VCC to inhibit all write operations to the memory array; tie to Vss (or leave floating, internally pulled to Vss) to allow normal writes. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOT-23-5 |+| Category | Memory |+| Pins | 5 |++## Ordering variants++- `AT24C16M5M5/TR`+- `AT24C16M5N`+- `AT24C16M5M/TR`+- `AT24C16M5MT/TR`+- `AT24C16M5MM/TR`+- `AT24C16M5DQ3/TR`+- `AT24C16M5DQ2/TR`++## CAD (KiCad official)++- Symbol: `AT24C16M5`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/at24c16m5-datasheet.pdf) (21 pp, sha256 `3e86ae75d43fb087`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
