Description
The STLC2593 combines Bluetooth and FM tuner functionality into one product and is fully optimized for mobile applications such as mobile phones, smart phones, PDAs and portable media players. The required board space has been minimized, only 1 external component is needed, power consumption levels are targeted for battery powered devices and the integration allows a cost-effective solution. The reduction of external components eases the integration of the STLC2593. Compared to its successful predecessor, the STLC2590, the STLC2593 supports the latest Bluetooth specification V2.1 (“Lisbon“) + EDR and further optimizes the RF performances and cost.
