Software-defined SAF4000 simplifies logistics for car OEMs—a single hardware device covers all broadcast requirements via end-of-line firmware update.

NXP Semiconductors has introduced the SAF4000, a fully integrated software defined radio solution capable of covering all global broadcast audio standards, including AM/FM, DAB+, DRM(+) and HD.

The SAF4000 is software-defined, thus simplifying the logistics for car OEMs—a single hardware device covers all regional broadcast requirements via end-of-line firmware update, saving cost and complexity for multiple hardware and software offerings. In combination with the newly announced i.MX 8 applications processor and the TDF8534 smart Class D amplifier, NXP is now able to offer a complete car infotainment platform with integrated audio.

Car radios used to require a large printed circuit board and six different ICs, but with NXP’s SAF4000, the core of the radio now fits on a fingertip and covers all global broadcast audio standards in one board, according to the company. The integration provided by the SAF4000 also reduces complexity and system costs while delivering a 60% power and space savings.

“One-chip means a significantly smaller hardware footprint, easier development and simple worldwide integration with the ability to receive multiple different digital as well as analog radio standards and to switch between them via software," said Torsten Lehmann, senior vice president and general manager of Car Infotainment and Driver Assistance at NXP.

Engineering samples are available for NXP's lead customers.
