German-based company offers the ultimate smart lock system with energy harvesting technology

Infineon Technologies the German-based semiconductor manufacturer company introduces the NAC1080, a single chip serving several purposes. The NAC1080 is a Near-field Communication Technology (NFC) controller that allows consumers to share small payloads of data between an NFC tag and an Android-powered device.

The NAC1080 is designed to recognize circuits in NFC phones and can harvest power to initiate the smart lock’s motor with embedded security features and a 32-bit ARM Cortex M0 CPU in order to verify whether the phone is allowed to be opened or locked.

The company stated that they will supply the antenna, 3V mini-motor, and capacitors in place of the battery to make sure that it doesn’t eat up the phone’s battery. The Infineon NFC interface is compliant with ISO 14443 type A with Arm 32bit Cortex-M0 microcontroller core and dual operation mode both passive and battery mode. It has a memory of 16KB RAM, 16KB ROM as bootloader, and 60KB NVM. The software it uses is SPI, I2C, and UART along with supporting up to 250mA integrated half-bridge load current.

The NAC1080 is able to support emergency power supply to battery-powered devices and has a fully flexible software-defined function.

The company said that the motors are typically expected to turn the lock’s secret by not moving a large portion of the lock. The NFC field strength offers effective function with the help of the phone’s antenna, the lock’s antenna, and how closely the lock and phone are placed together.

The NAC1080 has an IC architecture and smart partitioning between hardware and software enabling the consumers to utilize it maximum. However, according to the company, this can not be used as the front door lock as of yet since it requires more complex development because “the response time for the more complex door is longer.”
