Ultra-low power, multiprotocol wireless MCUs from NXP
To maximise performance from a coin cell battery, NXP’s K32W061/41 MCU has multiple low power modes and low transmit/receive radio power requirements.
The K32W061 and the K32W041 integrate an IEEE 802.15.4 radio for Thread and Zigbee, Bluetooth Low Energy 5.0 and the integrated NFC NTAG (K32W061). The devices are able to operate in the -40 ℃ to +125 ℃ temperature range. NXP has used its wireless expertise and MCU capabilities to combine connectivity standards with the intelligent peripherals These peripherals support:
• Home and building automation
• Security and access control
• Smart thermostats and locks
• Gateways and sense sensor networks applications
The K32W061/41 wireless MCUs are based on an Arm Cortex M4 core operating at 48MHzwhich is supported by 640 KB of flash and 152 KB SRAM, providing enough space and flexibility for complex applications and OTA updates. An optional NFC NTAG provides standardized out-of-band communications to dramatically simplify the pairing process. The multiprotocol radio features an integrated power amplifier capable of up to + 11dBm output for long-distance transmission. It supports Bluetooth Low Energy 5.0, Zigbee, and OpenThread wireless network protocol stacks.
Product Enablement and Support
• NXP’s MCUXpresso software development kit (SDK) for the K32W061/41 wireless MCUs is compatible with the latest toolchains from IAR and NXP’s MCUXpresso IDE.
• The NXP IoT Toolbox smart device application and connectivity tool helps developers evaluate RF performance and test more efficiently.
• Hardware development support with the NXP IoT Development Kit, part number IOTZTB-DK006, that provides the ideal prototyping platform of a complete IoT design.
• Additional development hardware includes a USB dongle, part number OM15080-K32W for Bluetooth LE, Thread and Zigbee networks
