"Potential applications range from medical patches and disposable testers, to data loggers, smart thermostats, smart locks and sensor inserts," according to the company.<\/p>\n
An integrated circuit called the NGC1081 can be temporarily powered by a field NFC of the phone or continuously from a ~3.3 V power source - for example, a 3 V battery.<\/p>\n
\u201c Together with the sensor's naturally galvanically isolated interface, these features open up countless possibilities for creating battery-free, low-maintenance sensor use cases. This is particularly useful for applications where the power supply must be galvanically isolated to meet safety requirements,\u201d Infineon said.<\/p>\n
Inside Arm Cortex-M0 microcontroller, NFC ISO14443 type A interface, 250mA 3.6V H-bridge motor driver, 12-bit SAR ADC with four analog inputs, analog output supported by 10-bit DAC, comparator, current-to-voltage converter and a thermometer (\u00b10.3\u00b0C from 0 to +45\u00b0C, \u00b10.4\u00b0C below -20\u00b0C and above +85\u00b0C). There are also eight GPIO pins, some with PWM capabilities. SPI, I2C and UART interfaces are provided.<\/p>\n
The system ROM library contains driver functions for configuring and controlling the H-bridge, and built-in security includes a hardware AES accelerator and a true random number generator.< \/p> <\/p>\n
"The availability of mobile phone connectivity enables the cloud-based business model," the company said. \u201cThis is supported by a mailbox concept that provides access control and security. Application-specific commands and messages from the open protocol interface can extend the protocol layer.\u201d<\/p>\n
