±2g/±4g/±8g, Low g, 10-bit Digital Accelerometer
- This page contains information on a product that is not recommended for new designs.
This product is in “End of Life” status, we recommend FXLS8971CF or FXLS8974CF as a replacement. In cases where MMA845xQ is absolutely required, customers may reach out to Rochester electronics to check available stock.
The MMA8453Q is a smart low-power, three-axis capacitive micromachined accelerometer with 10 bits of resolution. This accelerometer is packed with embedded functions with flexible user-programmable options configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. The MMA8453Q has user-selectable full scales of ±2g/±4g/±8g. The device can be configured to generate inertial wake-up interrupt signals from any combination of the configurable embedded functions allowing the MMA8453Q to monitor events and remain in a low-power mode during periods of inactivity. The MMA8453Q is available in a 3 mm x 3 mm x 1 mm QFN package.
