- No Longer Manufactured
- MMA8453Q
±2g/±4g/±8g, Low g, 10-bit Digital Accelerometer
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
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.
