STLC2416中文资料意法半导体数据手册PDF规格书

DESCRIPTION

The STLC2416 from STMicroelectronics is a Bluetooth™ baseband controller with integrated 4 Mbit flash memory. Together with a Bluetooth™ Radio this product offers a compact and complete solution for short-range wireless connectivity. It incorporates all the lower layer functions of the Bluetooth™ protocol.

The microcontroller allows the support of all data packets of Bluetooth™ in addition to voice. The embedded controller can be used to run the Bluetooth™ protocol and application layers if required. The software is located in the integrated flash memory.
