MC3479 from MEMSIC, 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 | SCK_SCL | input | Serial clock input for I2C/SPI interface; requires typical 4.7kΩ pull-up resistor to VDD per I2C Fast-Mode specification. |
| 2 | CSN | input | SPI chip select input (active low); must connect to VDD when I2C interface is used. |
| 3 | DOUT_A6 | output | Serial data output (MISO) for SPI; I2C slave address bit 6 selection. |
| 4 | DIN_SDA | bidirectional | Serial data input (MOSI) for SPI and bidirectional open-drain serial data line (SDA) for I2C; requires typical 4.7kΩ pull-up resistor to VDD. |
| 5 | NC | unconnected | No connection. |
| 6 | GND | power_in | Ground reference (0V). |
| 7 | VPP | power_in | Substrate bias pin; must connect to GND. |
| 8 | NC | unconnected | No connection. |
| 9 | VDD | power_in | Power supply input; operating voltage range 1.7V to 3.6V. |
| 10 | NC | unconnected | No connection. |
| 11 | INTN 2 | tri_state | Interrupt output (active low); configurable as open-drain (requires 4.7kΩ pull-up) or push-pull via GPIO control register 0x33 bits 7:6. |
| 12 | INTN 1 | tri_state | Interrupt output (active low); configurable as open-drain (requires 4.7kΩ pull-up) or push-pull via GPIO control register 0x33 bits 3:2. |
