NXP targets eco-friendly smart home devices

1 min read

NXP Semiconductors has introduced the K32W061/41, a new family of ultra-low power, multiprotocol wireless microcontrollers (MCUs).

These low power devices complement the company’s recently introduced pin-compatible JN5189/88 (Thread/Zigbee) and QN9090/30 (Bluetooth® LE) MCUs and provide original equipment manufacturers (OEMs) with an easier migration path to support current and emerging smart home and building use cases.

In today's mart home and IoT devices reducing power consumption is critical and so there is a need to maximize the performance from a single coin cell battery. The K32W061/41 MCU achieves this via multiple low power modes and low transmit/receive radio power capabilities.

“The demand for ultra-low power connectivity in the smart home continues to grow as does the number of wireless technologies to choose from,” said Tom Pannell, senior marketing director for connectivity solutions at NXP. “With the launch our multiprotocol wireless microcontrollers, NXP is providing ultra-low power performance for connected applications by leveraging the breadth and expertise of our technology portfolio to deliver solutions that make it easier for OEMs to design robust and feature-rich Internet of Things devices with Bluetooth LE, Zigbee and Thread.”

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 ℃).

As a founding member of the Zigbee Alliance and Thread Group, co-founder of NFC Forum and member of Bluetooth SIG, NXP has been able to leverage its wireless expertise along with its broad MCU capabilities to integrate the latest connectivity standards with the proper intelligent peripherals These peripherals support a range of use cases that include:

• Home and building automation
• Security and access control
• Smart thermostats and locks
• Gateways and sense sensor networks applications

The K32W061/41 wireless microcontrollers 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 standardised out-of-band communications to 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.
