KX022-1020 from ROHM, in a LGA-12(2x2). 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 | SDO/ADDR | bidirectional | Serial Data Out during 4-wire SPI communication; also selects the least-significant bit of the device I2C slave address (ADDR) when the part is used in I2C mode. |
| 2 | SDI/SDA | bidirectional | SPI serial data input (SDI) in SPI mode; bidirectional I2C serial data line (SDA) in I2C mode. Requires an external pull-up (min 1.5 kΩ) to IO_VDD for I2C operation. |
| 3 | IO_VDD | power_in | Power supply input for the digital communication I/O pads. Operating range 1.7 V to VDD. Optionally decoupled to GND with a 0.1 µF ceramic capacitor. |
| 4 | TRIG | input | External trigger input for the FIFO sample buffer (used in Trigger buffer mode). Tie to GND when the external trigger feature is not used. |
| 5 | INT1 | output | Physical programmable interrupt output 1. Polarity, latch behavior, and source events are configured via the INC1/INC4 registers. Leave floating if unused. |
| 6 | INT2 | output | Physical programmable interrupt output 2. Polarity, latch behavior, and source events are configured via the INC5/INC6 registers. Leave floating if unused. |
| 7 | VDD | power_in | Main analog supply input (1.71 V to 3.6 V, 2.5 V typical). Decouple to GND with a 0.1 µF ceramic capacitor. |
| 8 | GND | power_in | Device ground return. |
| 9 | GND | power_in | Device ground return (second GND pin). |
| 10 | nCS | input | Chip-select / interface-mode select. Tie to GND to enable SPI (and disable I2C); tie to IO_VDD to enable I2C (and disable SPI). Must not be left floating. |
| 11 | NC | unconnected | No internal connection. May be tied to VDD, IO_VDD, GND, or left floating. |
| 12 | SCLK/SCL | input | Serial clock input for both SPI (SCLK, up to 10 MHz) and I2C (SCL, up to 3.4 MHz in HS-mode) communication. |
