NXP Semiconductors KIT1925MMA6263Q

Overview

KIT1925MMA6263Q from Freescale Semiconductor is a dual-axis ±1.5g micromachined accelerometer evaluation kit for the MMA6263Q sensor IC, featuring 900 Hz bandwidth, 2.2 mA supply current, ratiometric linear analog outputs (XOUT/YOUT), and integrated self-test functionality. It enables rapid prototyping of motion sensing in portable electronics and industrial monitoring systems.

For engineers reviewing the KIT1925MMA6263Q datasheet, KIT1925MMA6263Q pinout, KIT1925MMA6263Q application, or KIT1925MMA6263Q equivalent, this kit provides verified hardware interface, calibrated signal conditioning, QFN-16 footprint compatibility, and direct connection to microcontroller ADC inputs with recommended RC filtering - critical for tilt, impact, and vibration sensing validation.

Technical Context

The KIT1925MMA6263Q implements the MMA6263Q accelerometer in a ready-to-use evaluation platform with board-level decoupling (0.1 µF on VDD), 1 kΩ + 0.1 µF RC filters on XOUT/YOUT, and ST pin access for hardware-initiated self-test. It supports 2.7–3.6 V operation and delivers full-scale output swing from VSS +0.25 V to VDD –0.25 V.

This kit maps the MMA6263Q's 16-pin QFN-16 (Case 1477-02) package to through-hole or edge-mount headers, exposing VDD, VSS, XOUT, YOUT, and ST while leaving all N/C pins unconnected. Power-up response time is 0.7 ms, and noise performance is 2.5 mV_RMS (0.1 Hz–1 kHz).

FAQ

What is the purpose of the KIT1925MMA6263Q evaluation kit?

The KIT1925MMA6263Q evaluation kit provides a fully assembled, tested platform for the MMA6263Q ±1.5g dual-axis accelerometer. It includes proper decoupling, RC filtering, and header access to all functional pins (VDD, VSS, XOUT, YOUT, ST), enabling immediate analog signal acquisition and self-test verification without custom PCB design. KIT1925MMA6263Q accelerates firmware development and system-level validation.

Does KIT1925MMA6263Q support direct connection to a microcontroller ADC?

Yes - KIT1925MMA6263Q features buffered ratiometric analog outputs (XOUT/YOUT) compatible with standard 10-bit or 12-bit microcontroller ADCs. The board incorporates 1 kΩ series resistors and 0.1 µF shunt capacitors per output to suppress switched-capacitor filter clock noise, ensuring clean sampling. KIT1925MMA6263Q requires only VDD and GND connections to operate within 2.7–3.6 V.

How is self-test performed using KIT1925MMA6263Q?

Apply a logic-high signal (≥0.7×VDD) to the ST pin on KIT1925MMA6263Q. This triggers internal electrostatic actuation of the MEMS sensing element, producing a calibrated output shift (~0.9×VDD) on both XOUT and YOUT. Observed voltage change confirms mechanical mobility and analog signal path integrity. KIT1925MMA6263Q requires no external components to execute this test.

What is the acceleration range and sensitivity of the sensor on KIT1925MMA6263Q?

The MMA6263Q sensor on KIT1925MMA6263Q has a full-scale range of ±1.5 g and nominal sensitivity of 800 mV/g at 25°C and 3.3 V supply. Output is linear and ratiometric: zero-g output is VDD/2 (e.g., 1.65 V at 3.3 V), increasing by ~800 mV per g of acceleration along X or Y axis. KIT1925MMA6263Q maintains this specification across its –20°C to +85°C operating temperature range.

Is KIT1925MMA6263Q compatible with other MMA626xQ variants?

KIT1925MMA6263Q is mechanically and electrically compatible with all MMA626xQ family members (MMA6260Q/MMA6261Q/MMA6262Q) due to identical QFN-16 (Case 1477-02) packaging, pinout, and interface. However, bandwidth (900 Hz), noise (2.5 mV_RMS), and supply current (2.2 mA) are specific to the MMA6263Q IC mounted on KIT1925MMA6263Q - not interchangeable with lower-bandwidth variants without revalidation.
