STLC2411
2 DESCRIPTION
The STLC2411 offers a compact and complete solution for short-range wireless connectivity. It incorpo-
rates 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 Blue-
tooth™ protocol and application layers if required. The software is located in an external memory accessed
through the external memory interface.

3.3 I/O specifications
Depending on the interface, the I/O voltage is typical 1.8V (interface to the flash memory) or typical 3.3V
(all the other interfaces). These I/Os comply with the EIA/JEDEC standard JESD8-B.
