IFXSP4900111XTMA2
Overview
The SP4900111XTMA2 is a highly integrated Tire Pressure Monitoring System (TPMS) sensor from Infineon that combines a pressure sensor with an ARM Cortex-M0+ microcontroller core. Operating at up to 48 MHz, this AEC-Q100 qualified device is designed to measure pressure and transmit data via standard automotive protocols while maintaining ultra-low power consumption. It includes 19 KB of flash memory and a 14-pin DSOSP package optimized for the harsh environment inside a vehicle tire.
Why Choose This Part
This device offers a significant reduction in system complexity by integrating a pressure sensor, temperature sensor, and a 32-bit MCU into a single package. Its ultra-low sleep current of 6uA and run current as low as 1.57mA are critical for battery-powered automotive sensors that must last for years without service.
Applications
Getting Started
Development requires an ARM-compatible toolchain such as Keil MDK or IAR Embedded Workbench for the Cortex-M0+ core. Engineers should utilize Infineon's automotive-grade software libraries and a compatible SWD debugger for programming and real-time debugging via the 14-pin DSOSP interface.
