NXP Semiconductors RDMMA865X

Overview

RDMMA865X from NXP (formerly Freescale) is a complete evaluation kit containing four PCBs: MMA8652FC and MMA8653FC accelerometer daughter cards, sensor interface board, and LFSTBUSB communication board - enabling full functional validation of the Xtrinsic MMA865xFC 3-axis accelerometers with PC-based Sensor Toolbox software. It supports 12-bit and 10-bit configurations, configurable sample rates from 1.5 to 800 Hz, FIFO-based power management, and motion-triggered interrupts including tap, freefall, orientation, and transient detection.

For engineers reviewing the RDMMA865X datasheet, RDMMA865X pinout, RDMMA865X application, or RDMMA865X equivalent, this kit delivers validated hardware-software integration for rapid prototyping of low-power motion-sensing applications in mobile, wearable, and industrial edge devices - with direct support for I²C interface configuration, interrupt mapping, and real-time sensor data streaming via USB bridge.

Technical Context

The RDMMA865X kit implements a modular architecture: two daughter cards host the MMA8652FC (12-bit, 1 mg/count sensitivity) and MMA8653FC (10-bit, industry-leading ultra-low power) accelerometers in 2 mm × 2 mm × 1 mm DFN-12 packages; the sensor interface board provides level-shifting, voltage regulation, and interrupt routing; the LFSTBUSB board acts as an I²C-to-USB bridge with embedded firmware for Sensor Toolbox compatibility.

All boards are designed for plug-and-play operation with Windows-based Sensor Toolbox software, supporting register-level configuration, real-time data plotting, FIFO watermark triggering, and motion event logging - without requiring custom driver development or hardware modification.

FAQ

What is the RDMMA865X used for?

The RDMMA865X is a complete evaluation kit for the MMA8652FC and MMA8653FC accelerometers. It enables engineers to validate motion-sensing functionality - including tap, orientation, freefall, and transient detection - using NXP's Sensor Toolbox PC software. The RDMMA865X supports rapid firmware testing, interrupt behavior analysis, and system-level power profiling without custom hardware design.

Does the RDMMA865X include the LFSTBUSB board?

Yes, the RDMMA865X is explicitly defined as a complete kit containing four PCBs: the MMA8652FC daughter card, MMA8653FC daughter card, sensor interface board, and the LFSTBUSB communication board. Unlike the LFSTBEB865x (which excludes LFSTBUSB), the RDMMA865X integrates all components required for immediate USB-connected evaluation of both accelerometers.

Can the RDMMA865X be used with both MMA8652FC and MMA8653FC sensors simultaneously?

Yes, the RDMMA865X includes dedicated daughter cards for both the MMA8652FC and MMA8653FC accelerometers. The sensor interface board routes I²C signals and interrupts independently to each device, allowing side-by-side comparison, cross-configuration testing, and dual-sensor firmware validation within the same RDMMA865X setup.

Is Sensor Toolbox software required to operate the RDMMA865X?

Yes, the RDMMA865X relies on NXP's official Sensor Toolbox PC application for full functionality - including register read/write, real-time data streaming, FIFO monitoring, and motion event visualization. The LFSTBUSB board's firmware is designed exclusively for Sensor Toolbox compatibility; no standalone drivers or third-party software interfaces are supported out of the box.

What power sources does the RDMMA865X support?

The RDMMA865X is USB-powered via the LFSTBUSB board (5 V input). Onboard regulators deliver 1.8 V and 3.3 V to the MMA8652FC and MMA8653FC daughter cards, supporting their specified operating ranges (1.71–3.6 V). No external power supply is needed - the RDMMA865X operates fully from a standard USB port during evaluation and development.
