A tiny hardware design and eBOM

CSR's design for a Wi-Fi internet radio, RadioPro, requires just two major ICs:

• UniFi-1 -  an 802.11 b/g device targeted at the portable embedded systems market
• MAP -  a multimedia applications processor combining DSP and 16-bit RISC cores, with a high-quality CODEC (16-bit stereo with 95 dB SNR).

Combined with Flash and SRAM and the external components required, the cost in high volume is just $15.

All developers need to add to this core is an LCD and user interface buttons.

CSR's demonstration hardware for this application shows that the radio can be built on a form-factor of just 5x5 cm - making it ideal for use in small portable/wearable radios. Note that this example implementation uses a single-sided PCB.

CSR provides Gerber files for the RF section of the design. Users can employ CSR's choices for the rest of the design as provided, or customise it using the development tool.
