MMA9553L中文资料智能计步传感器数据手册恩XP规格书

描述 Description

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

特性 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 slave 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
