NXP Semiconductors released what it describes as a low power and long range wireless MCU and accompanying smart home and smart lighting solutions, featuring certified ZigBee LightLink, Home Automation, GreenPower software stacks. The JN5169 also boasts what the company claims as a market-first NFC-commissioning option that lets users connect systems intuitively in a single tap.

An on-chip 10dBm power amplifier within the solution doubles the connectivity range of NXP's existing smart home products. It also features the ability to connect with 250 nodes allowing for it to be deployed in a range of uses in homes and industrial environments. ZigBee 3.0 and Thread ready, the JN5169 flaunts a novel toolchain for software development allows up to 15 per cent code size reductions and features extensive debugging capabilities, stated NXP.

Intuitive one-touch commissioning using NFC connectivity ensures that the devices can be easily yet securely paired without sending network details over-the-air, thus strongly reducing the threat of hacking.

To support the JN5169, NXP is launching three design references for white, tunable white and RGB(W) colour lamps, which reduce the total build cost of smart lighting solutions up to 25 per cent. With 512KB embedded flash memory, there is enough memory available on the product to enable over-the-air software upgrades, meaning that expensive external flash memory is no longer required, leading to additional cost savings. The lamp reference designs are complemented by wireless switches, remotes, wall panels, sensors, smart plugs and gateways as well as control by cloud services from NXP and its eco-system partners.

The JN5169 also features 14mA receive current allowing to reduce the standby power of bulbs down to an ultralow 100mW; only 20mA transmit current at 10dBm that is at least 40 per cent lower than other products in the market thus maximising battery life of wireless nodes; and the use of low cost 85C crystals for smart bulbs instead of more expensive 125C specified crystals enabled by innovative circuit and software techniques

The JN5169 product is being adopted by leading players in the smart lighting market, including TCP Inc. and Leedarson.
