NXP Semiconductors KITFXLC95000EVM

Overview

KITFXLC95000EVM from NXP Semiconductors (formerly Freescale) is an evaluation kit for the FXLC95000CL intelligent motion-sensing platform, integrating a 3-axis MEMS accelerometer and 32-bit ColdFire V1 MCU in a 24-pin LGA package. It supports autonomous sensor processing, local decision-making for gesture recognition and pedometer functions, and acts as a configurable sensor hub with master I2C/SPI interfaces.

For engineers reviewing the KITFXLC95000EVM datasheet, KITFXLC95000EVM pinout, KITFXLC95000EVM application, or KITFXLC95000EVM equivalent, this page delivers verified hardware configuration details, supported firmware frameworks (ISF/CodeWarrior), power management modes, sensor hub topology, and host interface options - all critical for rapid prototyping of motion-aware embedded systems.

Technical Context

The KITFXLC95000EVM implements the FXLC95000CL device in a ready-to-use board layout with onboard voltage regulation (1.8 V digital/analog, 1.71–3.6 V I/O), I2C/SPI level-shifting circuitry, and debug header for BDM-based programming. It exposes all 16 RGPIO pins, dual I2C ports (slave + master), queued SPI master, analog inputs AN0+/AN1−, and interrupt lines INT_I/INT_O.

Hardware features include jumper-selectable slave interface mode (I2C vs. SPI via RGPIO8), reset control, ferrite-bead filtered analog supply, and decoupling capacitors per power domain (VDD, VDDA, VDDIO). The board enables full validation of low-power operation - including deep-sleep wake-on-interrupt and host-offload scenarios - using the Xtrinsic Intelligent Sensing Framework (ISF).

FAQ

What is the primary function of the KITFXLC95000EVM?

The KITFXLC95000EVM is an evaluation kit for the FXLC95000CL intelligent motion-sensing platform. It provides hardware access to all device interfaces - including dual I2C, queued SPI, analog inputs, and RGPIOs - enabling engineers to validate firmware, test sensor hub configurations, and implement gesture recognition or pedometer algorithms without custom PCB design. The KITFXLC95000EVM includes necessary power regulation, level shifting, and debug infrastructure to run the FXLC95000CL out-of-box.

Does the KITFXLC95000EVM support both I2C and SPI host communication modes?

Yes, the KITFXLC95000EVM supports both I2C and SPI slave interfaces to the host processor. A hardware jumper selects between them by configuring RGPIO8 (PDB_B) at power-up: low enables SPI slave mode, high enables I2C slave mode. Both interfaces are electrically isolated with pull-up resistors and level-shifting circuitry compatible with 1.8 V or 3.3 V host logic levels, ensuring reliable communication during KITFXLC95000EVM integration.

Can the KITFXLC95000EVM be used to evaluate sensor hub functionality with external sensors?

Yes, the KITFXLC95000EVM fully supports sensor hub operation. Its FXLC95000CL device exposes master I2C (SCL1/SDA1) and queued SPI (SCLK1/MOSI1/MISO1/SSB1) interfaces, plus differential analog inputs AN0−/AN1+, allowing concurrent connection of magnetometers, pressure sensors, gyroscopes, or other analog/digital peripherals. The KITFXLC95000EVM's layout preserves signal integrity for these interfaces and enables real-time validation of local sensor fusion and host-offload behavior.

What software tools are required to program the FXLC95000CL via the KITFXLC95000EVM?

Programming the FXLC95000CL on the KITFXLC95000EVM requires CodeWarrior Development Studio for Microcontrollers (Eclipse-based IDE) and the Xtrinsic Intelligent Sensing Framework (ISF). ISF provides pre-built sensor libraries and a subscription-based data model for accelerometer outputs, while CodeWarrior enables flash programming, debugging via BKGD/MS pin, and custom firmware development. The KITFXLC95000EVM includes no onboard programmer - a separate BDM-compatible debug probe is needed.

How does the KITFXLC95000EVM facilitate low-power system design?

The KITFXLC95000EVM enables verification of all FXLC95000CL low-power modes - including deep-sleep with wake-on-INT_I, autonomous sensor sampling, and host-processor offload. By routing INT_O to the host and configuring RGPIO4 as interrupt input, the KITFXLC95000EVM demonstrates how the FXLC95000CL can keep the application processor powered down until motion events trigger wake-up. Power rails are independently decoupled to ensure accurate current measurement during KITFXLC95000EVM power profiling.
