> Philips Semi makes several of these

I have a tiny $2 radio using a surface mount TDA7088

http://www.semiconductors.philips.com/pip/TDA7088.html

I got it for dissecting purposes because it has just two push
buttons (Reset, Scan) and a volume pot. Runs on 2xAAA.
Single-sided PCB is 40mm x 25mm but it could have been
much smaller
