Chips/BCM2045

From Wiire

Broadcom BCM2045

BCM2045 is a programmable chip that handles bluetooth communications. It's commonly used as the main component in USB bluetooth devices (it's presumed that it's communicating with the wii via USB...)

This chip can be found on the Wii Console Bluetooth Daughterboard.

The datasheet is a horror to get, I'm looking for it.
