Description
The RA6W1 is a highly integrated ultra-low power Wi-Fi MCU integrating an Arm® Cortex®-M33 system processor with a dual-band 802.11a/b/g/n/ax Wi-Fi subsystem, on-chip memory, flexible peripheral interfaces, and power management features. This provides a standalone single-chip solution that can support complex low-power IoT solutions that require Wi-Fi network connectivity. Extremely low-power operation is accomplished by dynamically disabling elements of the MCU that are not in use, thus allowing a near zero level of power consumption when not actively transmitting or receiving data. Such low-power operation can extend the battery life up to a year or more, depending on the application. Built from the ground up for the Internet of Things (IoT), the RA6W1 is ideal for door locks, thermostats, sensors, pet trackers, asset trackers, sprinkler systems, connected lighting, smart home, home appliances, video doorbells, wearables, and other IoT devices.
