Frontier Silicon, a semiconductor supplier for mobile TV and digital radio, has partnered with SigmaTel Inc. to produce Atlas 2, a low-cost integrated platform for manufacture of combined digital audio broadcasting (DAB), FM and fully featured MP3 player. The platform brings together Frontier Silicon's Naples FS 2011 miniature tri-band DAB/FM digital radio module and SigmaTel's STMP3500 series MP3 processor and portable audio system-on-chip (SoC) to provide consumer electronics manufacturers with a customizable ready to manufacture solution for combined DAB/FM/MP3 handheld players with voice-recording capability.
Anthony Sethill, CEO of Frontier Silicon, said, “This is a significant new addition for the personal media player (PMP) market, since we can now enable DAB manufacturers to add MP3 functionality, as well as those making MP3 players to add DAB digital radio listening functions on their devices. Until now, there wasn't a readily available platform solution that could be easily customized by manufacturers and quickly deployed into mass production.”
The Naples FS 2011 module within Atlas 2 is a compact, low-power, high-performance DAB and FM OEM module designed for use in battery-powered products. It incorporates Frontier Silicon's Apollo RF front-end and Chorus DAB baseband processor. While SigmaTel's STMP3500 portable audio SoCs are highly integrated, battery-optimized ICs designed to decode compressed audio files such as MP3 files, using high-performance audio codec, DSP, USB interface, and general-purpose I/O. The SigmaTel SoC also supports MP3 and WMA audio format algorithms as well as security in WMA DRM (digital rights management).
The Atlas 2 platform can be configured to customer requirements, including optional hardware FM, selectable memory size, keyboard and LCD options. It features a full MMI interface implemented on either a 1.1-inch single-color OLED or backlit graphics FSTN display. A separate customizable keyboard PCB provides navigation and short cut keys to menus and functions. The headphone antenna acts as the Band-II (FM) and Band-III antenna. File storage can be to internal Flash or to SD card.
