The NAC1080 from Infineon is an NFC actuation controller with integrated H-bridge and energy harvesting modules, enabling cost-effective development of passive smart actuators like passive locks. The low-power ARM Cortex-M0 based microcontroller with integrated NFC frontend, sensing unit, motor driver, and energy harvesting function enables customers to develop smart actuation devices with minimum system BOM requirement.
The NAC1080 includes hardware security functions such as secure area in flash, 128-bit AES accelerator and true random generator. The microcontroller has 16 kB ROM for the bootloader, 16 kB RAM and 60 kB non-volatile memory. A separate secure element can be connected via the digital interface on demand, which includes SPI, I2C and UART.
The integrated H-bridge supports up to 250 mA load current, allowing for potential applications such as passive NFC locks, emergency power supply for battery powered devices, and as an NFC interface for home appliances.
