Integrated Wi-Fi+Bluetooth® MCU Modules


Wi-Fi, Bluetooth, Micro Control Unit - All communication features in a single small package!

Wi-Fi, Bluetooth, Micro Control Unit - All communication features in a single concise package!

Wi-Fi and Micro Control Unit (MCU) with ARM Cortex Core, are integrated into a single compact package.

Since it is possible to install the device driver, WPA2 and other supplicants, protocol stacks such as TCP/IP, Bluetooth profile, Application software, etc. into the MCU, customer's IoT devices can work easily, even without a host MCU.

Supports Infineon WICED Studio and Various Protocols Essential to IoT

Infineon WICED Studio SDK is a turn-key solution which can provide quick and easy development environment for IoT devices.

WICED supports many Wi-Fi functionalities such as STA/SoftAP mode, WPA2-PSK(AES), WPS and Wi-Fi Direct. WICED also supports Bluetooth Classic BR/EDR and Bluetooth Low Energy mode such as RFCOMM/SPP and GATT profile.

Supported protocols are not only basic protocols like TCP/IP, HTTP but also security protocols such as SSL/TLS, MQTT and Apple HomeKit for IoT.
