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 on the SOIC-8 package; leave floating or tie to GND for improved EMC. |+| 2 | NC | unconnected | No connect. Not internally bonded on the SOIC-8 package; leave floating or tie to GND for improved EMC. |+| 3 | NC | unconnected | No connect. Not internally bonded on the SOIC-8 package; leave floating or tie to GND for improved EMC. |+| 4 | GND | power_in | Ground reference for the device. Connect directly to the system ground plane. |+| 5 | SDA | bidirectional | I2C serial data line. Open-drain, requires an external pull-up to VCC. Supports standard I2C speeds up to 1 MHz. IO levels 1.8V-5.5V. |+| 6 | SCL | input | I2C serial clock input. Driven by the bus master; requires an external pull-up to VCC. IO levels 1.8V-5.5V. |+| 7 | NC | unconnected | No connect. Not internally bonded on the SOIC-8 package; leave floating or tie to GND for improved EMC. |+| 8 | VCC | power_in | Positive supply input, 2.0V to 5.5V. Bypass locally with a 0.1 µF ceramic capacitor to GND. Typical sleep current <150 nA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip Tech |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `ATECC608A-SSHDA-T`+- `ATECC608A-SSHDA-B`+- `ATECC608A-SSHDA-TSSHCZ-T`+- `ATECC608A-SSHDA-TSSHCZ-B`+- `ATECC608A-SSHDA-TMAHDA-T`+- `ATECC608A-SSHDA-TMAHDA-S`+- `ATECC608A-SSHDA-TMAHCZ-T`+- `ATECC608A-SSHDA-TMAHCZ-S`++## CAD (KiCad official)++- Symbol: `ATECC608A-SSHDA-T`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Microchip Tech datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8589793543352057856) (28 pp, sha256 `5b9164c658d321e3`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
