MMA9553L|Intelligent Pedometer Sensor

Overview

Archived content is no longer updated and is made available for historical reference only.

The MMA9553L pedometer sensor integrates a high accuracy, high resolution MEMS accelerometer, a 32-bit low power embedded MCU, flash memory and a dedicated architecture to manage additional sensors. Featuring:

A highly accurate, fast response, pedometer with accurate step counting and stride length detection
Capability of adding additional motion sensing detection, such as threshold detection or wake-up detection
Significant power savings of your overall system as well as step detection and counting while the rest of the system can be turned off
Sensor hub functions to enable a large breadth of pervasive portable or wearable applications

Features

Hardware

Three accelerometer operating ranges:
- ±2 g is suitable for orientation detection
- ±4 g covers most regular human dynamics such as walking and jogging and is used for the pedometer functionality
- ±8 g detects most abrupt activities useful for gaming purposes
One follower SPI or I2C interface operating at up to 2 Mbps, dedicated to communication with the host processor. The value of the I2C, 7-bit address is 0x4C.
Eight selectable output data rates (ODR), from 488 Hz to 3.8 Hz
10-, 12-, 14-, and 16-bit trimmed ADC data formats available
1.8 V supply voltage
32-bit CPU with MAC unit
Extensive set of power-management features and low-power modes
Integrated ADC can be used to convert external analog signals
Single-Wire, Background-Debug Mode (BDM) pin interface
16-KB flash memory

Software

This device can be programmed to provide any of the following:

Six directions of orientation
Pedometer
- Activity level
- Step count
- Distance
- Calorie count
Auto wake/sleep
Embedded, smart FIFO
Power management
