{"title":"3-Axis MEMS Accelerometer - MMA8452Q","handle":"3-axis-mems-accelerometer-mma8452q","url":"/products/3-axis-mems-accelerometer-mma8452q","description":"The MMA8452Q is a low-power, 3-axis capacitive MEMS accelerometer with 12-bit resolution. Packed with embedded motion-detection functions and configurable interrupt outputs, it can monitor events autonomously while staying in a low-power state — reducing the need for the host processor to continuously poll data.\n\nUser-selectable full-scale ranges of ±2g, ±4g, and ±8g are available with both high-pass filtered and unfiltered data in real time. This is the bare IC in a QFN package — a breakout board or custom PCB is required for use.\n\nKey Features\n\n\n12-Bit Resolution – Also supports 8-bit output for faster reads\n\nSelectable Range – ±2g, ±4g, or ±8g full-scale\n\nI2C Interface – Up to 2.25 MHz with 4.7 kΩ pull-ups\n\nTwo Programmable Interrupt Pins – Six configurable interrupt sources\n\nEmbedded Motion Detection – Three channels, plus portrait/landscape orientation with hysteresis\n\nUltra-Low Power – 6 µA to 165 µA current consumption\n\nOutput Data Rates – 1.56 Hz to 800 Hz\n\nReal-Time High-Pass Filter – Filtered data available alongside raw output\n\n\nSpecifications\n\n\nSensor IC: MMA8452Q\n\nPackage: 3 × 3 × 1 mm QFN\n\nSupply Voltage: 1.95–3.6 V\n\nInterface Voltage: 1.6–3.6 V\n\nInterface: I2C\n\nCurrent Consumption: 6–165 µA\n\n\nIdeal For\n\nLow-power motion and orientation sensing\nWearable and portable device designs\nInertial wake-up and tap detection applications\nCustom PCB designs requiring a compact accelerometer\n\n\nPackage Contents\n\n1× MMA8452Q Accelerometer IC (QFN package)\n\n\nResources\n\nDatasheet (PDF)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12216,"title":"Default Title","sku":"SF-COM-10953","price":5.79,"on_sale":false,"in_stock":true,"available_quantity":382,"option1":"Default Title"}]}
