IIM-42352 from TDK InvenSense, in a LGA-14(2.5x3). 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 | AP_SDO / AP_AD0 | bidirectional | SPI serial data output in 4-wire mode or I2C/I3C slave address LSB selection pin with configurable pull-up and pull-down. |
| 2 | RESV | unconnected | Reserved pin; no connect or connect to GND with optional pull-up enablement via PIN2_PU_EN register. |
| 3 | RESV | unconnected | Reserved pin; no connect or connect to GND with optional pull-up enablement via PIN3_PU_EN register. |
| 4 | INT1 / INT | output | Interrupt 1 output supporting both push-pull and open-drain drive circuits with optional pull-down and alternative function as all-interrupts-mapped pin. |
| 5 | VDDIO | power_in | IO power supply voltage input with operating range 1.71V to 3.6V requiring 10nF bypass capacitor. |
| 6 | GND | power_in | Power supply ground connection. |
| 7 | RESV | unconnected | Reserved pin; must connect to GND with optional pull-up enablement via PIN7_PU_EN register. |
| 8 | VDD | power_in | Primary power supply voltage input with operating range 1.71V to 3.6V requiring 0.1µF and 2.2µF bypass capacitors. |
| 9 | INT2 / FSYNC / CLKIN | bidirectional | Multi-function pin supporting Interrupt 2 output, frame sync input, or external clock input (31-50 kHz) selectable via PIN9_FUNCTION and mode registers with optional pull-down. |
| 10 | RESV | unconnected | Reserved pin; no connect or connect to GND with pull-up enabled by default and disableable via PIN10_PU_EN register. |
| 11 | RESV | unconnected | Reserved pin; no connect or connect to GND with pull-up enabled by default and disableable via PIN11_PU_EN register. |
| 12 | AP_CS | input | SPI chip select input active low or must connect to VDDIO when using I2C/I3C interface with configurable pull-up and pull-down. |
| 13 | AP_SCL / AP_SCLK | input | I2C serial clock (open-drain, 1 MHz maximum) or SPI serial clock input (24 MHz maximum) with configurable pull-up and pull-down. |
| 14 | AP_SDA / AP_SDIO / AP_SDI | bidirectional | I2C serial data (open-drain), SPI serial data I/O 3-wire mode, or SPI serial data input 4-wire mode with configurable pull-up and pull-down. |
