Yesterday iFixit.com found one in the new Apple iPod Touch. This is the first published instance of a device containing this chip but many more will follow. Broadcom has scored a coup with this device; it contains Wi-Fi, Bluetooth and FM, all on a single die fabricated on a 65nm process.
This is the most highly integrated connectivity chip (the term refers to all the non-cellular radios in a phone) yet to reach the market. Previous combo connectivity chips have combined Bluetooth with FM, and in one instance (from Marvell) Bluetooth with Wi-Fi. But the BCM4325 is the first to market with three radios. TI has announced, but not yet shipped, a similar chip with even more impressive specifications: the TI Wi-Fi will include 802.11n and the TI FM will include transmit as well as receive.
Connectivity technology in cell phones is evolving very rapidly, as the phone manufacturers accelerate their competition on the feature treadmill. Next will be GPS, driven this time by the network operators, who see location-based services as a potential goldmine. Two chip manufacturers have announced, but not yet shipped, combo Bluetooth, FM and GPS chips.
Connectivity chips were the subject of a report I wrote last year with the Linley Group; we will deliver an update with expanded coverage later this year.
