Pin Configuration
BMI160 Pinout — 14-VFLGA Package
| Pin Number | Pin Name | Type | Description |
|---|---|---|---|
| 1 | VDDIO | P | I/O Supply Voltage (1.2V to 3.6V) |
| 2 | CSB | I | Chip Select / I2C Address Select |
| 3 | SDO | I/O | SPI Data Output / I2C Address Select |
| 4 | SDA/SDI | I/O | I2C Data / SPI Data Input |
| 5 | SCL/SCK | I | I2C Clock / SPI Clock |
| 6 | GND | P | Ground |
| 7 | INT2 | O | Interrupt Output 2 |
| 8 | INT1 | O | Interrupt Output 1 |
| 9 | VDDIO | P | I/O Supply Voltage (1.2V to 3.6V) |

Notes
- Power pins: VDD (pin 13) powers the internal core; VDDIO (pins 1, 9) powers the I/O domain. Both must be within specification for proper operation.
- Primary Interface: Pins 2–5 support either I2C (SDA/SCL on pins 4–5, CSB and SDO tied appropriately) or SPI (4-wire or 3-wire mode).
- Secondary Interface: Pins 10–12 support OIS (Optical Image Stabilization) in SPI mode or can be used for secondary I2C magnetometer interface.
- Interrupt outputs: INT1 and INT2 (pins 8, 7) are configurable for various motion and data-ready events.
- Ground: Pins 6 and 14 must be connected to ground.
