Features
NGC1081 is an IC, suitable and optimized for NFC communication controlled actuation and
sensing. It contains a NFC transceiver, an actuation interface, a sensing unit, a microcontroller
and wired communication interfaces. NGC1081 is available in a 32-pin package.
The chip can operate in two different power supply modes:
• active supply mode:
- The chip is supplied by an external 3V power supply source (e.g. battery).
• passive supply mode:
- The chip is harvesting energy from the external NFC RF field. No additional external supply
source is required. Of course, operation of the chip requires the presence of the NFC field in this
use case. The chip can charge external capacitors, in order to store harvested energy. External
storing capacitors can be used to store the required amount of energy to initiate an actuation
action (e.g. to drive a motor).

-
• embedded Security
- embedded AES hardware accelerator
- True Random Number Generator (TRNG)
• Power Management
- Ultra Low Power power saving Mode available
- chip supply for almost all parts of the chip is switched off, except a small always-on power
domain
- entering power saving mode and configuring wake up sources is controlled by embedded
software
- chip can wake up by either detecting an external NFC RF field, expiration of an internal wake
Up Timer or an external trigger event on a dedicated pin
- software controlled CPU idle mode
- CPU clock control by software
- dedicated and software controlled switchable LDOs for sensing unit and flash memory
• Clock Generation
- integrated 28 MHz oscillator for internal system clock generation
- integrated ultra low power 32 kHz oscillator for "always on" standby clock generation
- integrated oscillator pads to support external 32 kHz crystal
• Power Supply modes
- passive supply Mode
- energy is harvested from the external NFC RF field and the power supply of the chip is
derived from the harvested energy
- no external supply source apart from the NFC RF field required
- active supply mode
- the chip is supplied by an external supply source and operational, if no NFC field is applied
• Product qualified according to JEDEC Standard
