Description

The STLC2690 combines Bluetooth V2.1 + EDR

and FM R(B)DS transceiver functionality on a

single chip designed in ST low power 65 nm

RFCMOS process. The device is fully optimized

for mobile phones, smart phones, PDAs and

portable multimedia player applications. The

required board space has been minimized. Power

consumption levels are optimized for battery

powered devices and the high integration level

allows a cost effective solution. The low external

BOM count allows easy integration of the

STLC2690 into products, enabling short time to

market.
