Multiprotocol wireless MCUs

Author: EIS Release Date: Jun 2, 2020


NXP has brought out a family of multiprotocol wireless MCUs which complement the company’s pin-compatible JN5189/88 (Thread/Zigbee and QN9090/30 (BLE) MCUs..

Lowering the power consumption is crucial to maximizing the performance from a single coin cell battery. NXP’s K32W061/41  MCU achieves this via multiple low power modes and low transmit/receive radio power capabilities.

The K32W061 and the K32W041 feature an IEEE 802.15.4 radio supporting Thread and Zigbee networking protocols, Bluetooth Low Energy 5.0 and an integrated NFC NTAG (K32W061). The devices also support a wide operating temperature range (-40 ℃ to +125 ℃).

The MCUs  are based on an Arm Cortex M4 microcontroller core running at 48MHz and include 640 KB of onboard flash and 152 KB SRAM, providing storage space and flexibility for complex applications and software over-the-air (OTA) updates.

The optional NFC NTAG provides standardized out-of-band communications to dramatically simplify the pairing process. The multiprotocol radio includes an integrated power amplifier capable of up to + 11dBm output making long distance transmission possible.

Additionally, it supports Bluetooth Low Energy 5.0, Zigbee, and OpenThread wireless network protocol stacks.

Other support includes:

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
