NXP Semiconductors KIT315MPXY8300A

Overview

KIT315MPXY8300A from NXP Semiconductors (formerly Freescale) is a 315 MHz tire pressure monitoring system (TPMS) evaluation kit built around the MPXY8300A all-in-one sensor IC. It integrates a capacitive pressure sensor (100–450 kPa), 8-bit S08 MCU (16 KB Flash, 512 B RAM), 315 MHz PLL-based RF transmitter, dual-axis accelerometer (X/Z), and temperature sensor in a single SOIC-20WB package - enabling rapid prototyping of automotive TPMS transmitters.

For engineers reviewing the KIT315MPXY8300A datasheet, KIT315MPXY8300A pinout, KIT315MPXY8300A application, or KIT315MPXY8300A equivalent, this kit supports FMVSS 138-compliant TPMS development with motion-triggered wake-up, ASK/FSK modulation, low-power periodic reset via LFO, and integrated physical self-test for accelerometers.

Technical Context

The KIT315MPXY8300A provides a complete hardware platform to evaluate the MPXY8300A IC's end-to-end TPMS functionality: pressure/temperature sensing, motion detection via ±10g X-axis and ±60g Z-axis accelerometers, and 315 MHz RF transmission using ASK or FSK modulation. It includes on-board LF receiver circuitry for wake-up command reception at 125 kHz.

This kit implements the full signal chain - from capacitive pressure transduction and 10-bit ADC conversion to S08 MCU firmware execution, accelerometer-based event triggering, and RF packet formatting - all validated for operation across –40°C to +125°C and compliant with U.S. FMVSS 138 requirements for real-time under/over-inflation alerts.

FAQ

What is the primary function of the KIT315MPXY8300A evaluation kit?

The KIT315MPXY8300A evaluation kit enables functional validation and firmware development for the MPXY8300A TPMS sensor IC. It provides full hardware access to the integrated pressure sensor, 315 MHz RF transmitter, dual-axis accelerometer, and S08 MCU - allowing engineers to test motion-triggered wake-up, pressure reporting, ASK/FSK modulation, and LF command reception in realistic vehicle environments.

Does the KIT315MPXY8300A include the MPXY8300A IC pre-mounted?

Yes, the KIT315MPXY8300A includes a fully assembled evaluation board with the MPXY8300A IC mounted in its native SOIC-20WB package. The board features test points, programming headers, antenna interface, and 125 kHz LF receiver circuitry - all configured to demonstrate out-of-box operation of the MPXY8300A's complete TPMS signal chain.

Can the KIT315MPXY8300A be used for 434 MHz TPMS development?

No, the KIT315MPXY8300A is specifically configured for 315 MHz RF operation and is not compatible with 434 MHz protocols. For 434 MHz evaluation, NXP offers the separate KIT434MPXY8300A kit. The MPXY8300A IC itself supports both frequencies, but each kit's RF matching network, antenna, and firmware are tuned exclusively for its designated band.

What regulatory standard does the KIT315MPXY8300A help validate against?

The KIT315MPXY8300A supports development and testing aligned with U.S. Federal Motor Vehicle Safety Standard (FMVSS) 138, which mandates real-time tire pressure monitoring and driver alerting for under- or over-inflated tires. Its integrated pressure accuracy (±7 kPa), operating temperature range (–40°C to +125°C), and motion-triggered reporting behavior are designed to meet FMVSS 138 verification requirements.

Is the KIT315MPXY8300A compatible with CodeWarrior™ Development Studio?

Yes, the KIT315MPXY8300A is fully supported by CodeWarrior™ Development Studio v6.0 and later service packs, including debug interfaces for the S08 MCU core. Firmware updates, register-level configuration, and sensor calibration routines for the MPXY8300A can be developed and deployed using standard BDM Multilink tools (e.g., USBMULTILINKBDM) connected to the kit's BDM header.
