the ultimate in portability and access, yet the service providers do not make a buck from terrestrial broadcasts....this is the crux of the problem. Good luck locating a smart phone or a flip phone w/an FM receiver, you have about the same luck of locating a Detroit Lion with a Super bowl ring!!

My Motorola Flipside has an FM tuner. There is no built in antenna so you need to plug in a headset even if you want to use the internal speaker. I use it when traveling. No internet connection required and no subscription fee.

Everyone, Thanks for your interesting comments. This is Udayan from Cypress. First of all, the main intention of this article is to bring out the fact that FM radios are not dead. Second, the article primarily concentrated on FM radio as an accessory. The iPhone, iPad, google's nexus, HTC one and most other smart phones and tablets showcased at CES 2012 and MWC 2012, do not have an FM radio built in to it. Manufacturers are slowly phasing out the Radio, the accessory that we have discussed in this article is meant for such devices.

Udayan, let's please consider content: FM radio is of little use to me - pop culture drivel, bad music, etc. But AM is a different story. It's more interesting. Do any of these formulae change going to AM?

Hi, it would be nice to start the article with a direct reference to the chipset used. You work for Cypress, but an IC reference may be useful to many readers, regards, John

I've seen many low-end Chinese-made cell phones have FM receivers built-in along with dual sim card capability. So we'll probably be seeing more here in the US.

The earlier generation phones did have built-in FM radio. How many smart phones and tablets in the market today have built in FM radio ?

Listening to FM needs good amp and speakers to enjoy its quality.Generally in almost all the devices the FM radio is built in.Recently the refrigerators and washing machines do have this feature. USB based FM applications can go into those who wants to listen when working with their PC's and laptops.A limited application for this design.

Can you provide source code for the Windows app? It would be informative for demonstrating use of C# to interface to a USB device.

I have found that Jan Axelson's website to be a very useful resource for accessing USB devices http://www.lvr.com/usb.htm Jan wrote "USB Complete" which is still the best book on USB for software developers.

Looking at this article again, I thought of another use for the device. Retune it to the 160MHz band, tweak the software a bit and you have a weather alert radio. Very useful if things get dicey and cell comms is erratic.

i like the idea of reminding manufacturers about FM radio feature which most of us still enjoy in our daily lives

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
