As an NXP Gold Partner, NuCurrent’s early-access to NXP IC technology has allowed the team to create an NFC Wireless Power Development Platform that is capable of transferring meaningful power (up to 3W) while maintaining the widely used NFC data protocols (bi-directional data up to 848kbps), and deliver the world’s first-ever Wireless UART solution via NFC.
If you recall, low-frequency wireless power methods, such as Qi, do not have the data bandwidth to support UART baud rates, forcing reliance on two of the most common wireless communication technologies: WiFi and Bluetooth.
Unfortunately, WiFi and Bluetooth both experience interference and potential dropouts of communication when in environments where multiple devices operate in the same channels. To the average user, this manifests as slow connections, incorrect device pairing, and most importantly, communication security risks.
Further, as our engineers put it simply: Power and data don’t like each other. One will always try to degrade the other. NFC solves the issue of connecting to many devices because, as the name implies, the range between the transmitter (Tx) and receiver (Rx) is very small. So, the NuCurrent team thought: If the team has managed to hit the sweet spot of delivering high power and data with limited degradation to either, who is to say that UART isn’t possible either?
World’s First NFC Wireless UART
NuCurrent has developed the world’s first Wireless UART offering via NFC. This simple, low-cost solution utilizes the same chip to send power and data, implementing full-duplex serial communication over an NFC magnetic field, allowing designers to mimic physical data and power connections, such as USB, to create robust charging and data architectures for their products.
