BK3436T

AEC-Q100 compliant Bluetooth 5.2 (BR/LE) and 2.4 GHz proprietary system-on-chip (SoC)

Overview



The BK3436T is a highly integrated AEC-Q100 compliant Bluetooth 5.2 (BR/LE) and 2.4 GHz proprietary system-on-chip (SoC) targeting at automotive applications. It integrates a high-performance Bluetooth 5.2/2.4 GHz RF transceiver, a featurerich baseband processor, a memory controller, multiple analog and digital peripherals, as well as Bluetooth and 2.4 GHz proprietary protocol stacks.
Using advanced design techniques and ultra-low-power process technology, the BK3436T delivers high integration and minimal power consumption for automotive applications. Furthermore, the BK3436T is AEC-Q100 qualified at the Grade 2 temperature range (-40 to 105 °C), providing reliable performance across harsh environment such as on board units of electronic toll collection.
