Introduction
The i.MX25 family of processors offers integration that tailors itself to the connectivity requirements of todays automobile infotainment systems. These processors have been architected to meet auto infotainment requirements like CAN, USB connectivity, and audio connectivity, without many of the extra features only needed for high-end applications. As a result, the i.MX25 enables many of the features only available in high-end systems, but at a price point suitable for all vehicles.
At the core of the i.MX25 is Freescales fast, proven, power-efficient implementation of the ARM926EJ-S core, with speeds of up to 400 MHz. The i.MX25 includes support for up to 133-MHz DDR2 memory, integrated 10/100 Ethernet MAC, and two on-chip USB PHYs. The automotive versions of the i.MX25 offer AEC-Q100 grade 3 qualification to meet stringent automotive quality requirements. The device is suitable for a wide range of applications, including the following:

   • USB Connectivity for media storage/playback, personal media device interface, and firmware updates
   • Bluetooth™ connectivity for hands free phone calling and streaming audio from wireless devices like phones or PND
   • Control of the infotainment system through basic speech recognition or touch screen
   • Smart toll and metering applications
   • Secure data black box applications
