Frequently Asked Questions
How does the ATWINC3400-MR210CA combine Wi-Fi and Bluetooth 5.0 on a 3.3 V supply for IoT gateway designs?
The ATWINC3400-MR210CA integrates IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5.0 in a single 37-pin module powered from 3 V to 4.2 V nominal 3.3 V supply. This eliminates the need for two separate radio modules, reducing BOM cost and board area for IoT gateways that bridge BLE sensor networks to cloud infrastructure over Wi-Fi.
What host interface does the ATWINC3400-MR210CA use and which microcontrollers can it connect to for 802.11 data transfer?
The ATWINC3400-MR210CA uses an SPI host interface operating at standard SPI clock rates, making it compatible with virtually any microcontroller platform including 8-bit PIC, 32-bit SAM, ARM Cortex-M, and ESP families. The SPI interface transfers Wi-Fi and Bluetooth data frames to the host MCU with a 3.3 V logic level, requiring no external level shifters for 3.3 V systems.
What certifications and range can designers expect when deploying ATWINC3400-MR210CA in commercial products?
The ATWINC3400-MR210CA carries regulatory pre-certifications including FCC, IC, and CE, allowing product designers to use the module without re-certifying the radio subsystem. The on-board antenna supports typical Wi-Fi indoor range of 50 meters to 100 meters depending on environment, while Bluetooth 5.0 provides up to 40 meters range at reduced data rates, covering most smart home and industrial floor deployments.
