MC3479

MEMSIC · Accelerometers · LGA-12(2x2)

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.

CAD (KiCad official)

  • Symbol: MC3479
  • Footprint: Package_LGA:LGA-12_2x2mm_P0.5mm
  • 3D model: LGA-12(2x2) (KiCad packages3D, STEP)
  • 3D model files: mc3479-etched.step / mc3479-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mc3479.step / mc3479.glb are the bare package body.
