**MODSEMI** · Security Verification / Encryption ICs · SOP-8

MOD208-SHCF-U from MODSEMI, in a SOP-8. 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. Leave floating or tie to ground per board convention. |
| 2 | NC | unconnected | No connect. Leave floating or tie to ground per board convention. |
| 3 | NC | unconnected | No connect. Leave floating or tie to ground per board convention. |
| 4 | GND | power_in | Ground reference. Connect to system ground. |
| 5 | SDA | bidirectional | I2C serial data line. Open-drain bidirectional; requires external pull-up (typ. 10k) to VCC. Standard/Fast mode 100kHz/400kHz. |
| 6 | SCL | input | I2C serial clock input. Requires external pull-up (typ. 10k) to VCC. Supports 100kHz/400kHz operation. |
| 7 | NC | unconnected | No connect. Leave floating or tie to ground per board convention. |
| 8 | VCC | power_in | Power supply input. Operating range 1.65V to 3.6V (absolute max 1.62V min / 3.3V nominal per datasheet DC table). Decouple with a local capacitor (Cvcc) to GND. |

## CAD (KiCad official)

- Symbol: `MOD208-SHCF-U`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `mod208-shcf-u-etched.step` / `mod208-shcf-u-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mod208-shcf-u.step` / `mod208-shcf-u.glb` are the bare package body.
