STLC2500A

Overview

5/37

– Fast master I2C interface

■ Efficient support for WLAN coexistence in collocated scenario

■ Ciphering support up to 128 bits key

■ Software support

– Lower level stack (up to HCI)

– HCI Transport Layer: H4 (including proprietary extensions)

– HCI proprietary commands (e.g. peripherals control)

– Single HCI command for patch/upgrade download

■ Single power supply with internal regulators for core voltage generation

■ Supports 1.65 to 2.85 Volts IO systems

■ Total number of external components limited to 7 (6 decoupling capacitors and 1 filter)
