Infineon Technologies AG has developed a new programmable 32-bit ARM Cortex-M0 microcontroller with embedded near-field communication (NFC) frontend to enable cost-effective development of smart actuators, such as passive locks. Using the NFC interface, the new NAC1080 MCU enables devices to be controlled directly by smartphones. Advanced local and cloud functions can be extended within the mobile app offered by regional marketing partners which reduces the bill of material and supports miniaturized product design.
This MCU supports various operation modes and can be powered either in passive mode by the NFC field with the energy harvested from the mobile phone, or through a battery supply in active mode. It also provides an integrated AES128 accelerator and a true random number generator to enable data encryption/de-encryption in an ultra-low power environment. Besides the passive NFC lock application, this MCU can also be used as an emergency backup power supply application.
