NXP Semiconductors Document Number: MMA9555L Data Sheet: Technical Data Rev. 2.3, 8/2016 MMA9555L Intelligent Motion- MMA9555L Sensing Pedometer The MMA9555L intelligent motion-sensing pedometer is an extension of the MMA955xL intelligent sensor platform. This device incorporates a 3-axis MEMS accelerometer, signal conditioning, data conversion, and a 32-bit microcontroller. This intelligent motion-sensing sensor provides sophisticated pedometer functionality, activity level and six directional orientation monitoring. The integrated functionality of sensor initialization, calibration, data compensation, and computation functions off-loads CPU bandwidth from the system application processor. Therefore, total system power consumption is significantly reduced, because the application processor stays powered down until absolutely needed. In addition, the device can be configured for an autosleep/autowake capability. MMA9555L is available in a plastic LGA package the device is guaranteed to 16-pin LGA operate over the extended temperature range of 40 C to +85 C. 3 mm x 3 mm x 1 mm Case 2094-01 Features High resolution 3-axis accelerometer with Top view 16-bit ADC (0.061 mg/LSB 2 g) Selectable g range (2/4/8 g) and output data rates (488 Hz3.8 Hz) 2 One slave SPI or I C interface operating at up to 2 Mbps for communication with the host processor 1.8 V supply voltage low power consumption 2 A typical current at stop mode 16 15 14 V DD 1 13 RGPIO7 / AN1 117 A for pedometer running at active and 92 A at suspend BKGD-MS / 2 12 RGPIO6 / AN0 87 A when six-direction detection mode RGPIO9 RGPIO5 / RESETB 3 11 Complete built-in firmware for smart sensing intelligence PDB A / INT O SCL0 / RGPIO0 / Real time and preemptive application task scheduling 4 10 V SS SCLK Command interpreter support command/response and streaming 5 9 RGPIO4/INT V SS 67 8 mode Low-power pedometer with rich output information Step counting Speed, distance, calorie count estimation Activity level (rest, walking, jogging, running) Six-direction detection output Pin Connections Extensive set of power-management features and low-power mode GPIO2GPIO8 can be used for expanded configurable GPIO functions Minimal external component requirements All information provided in this document is subject to legal disclaimers.
