NAC1080 overview

The NAC1080 a NFC tag-side controller with integrated NFC connectivity (NFC), H-bridge for motor control, security
functions and optimized energy harvesting capability. It enables a single chip solution to build miniaturized, battery-
less, mobile phone controlled smart actuators such as passive locks.

Connectivity Actuation

NFC interface compliant to ISO Integrated H-bridge (control unit

14443 type A for connection with and 4 power switches) with drive
mobile phone current up to 250 mA

Security
Energy harvesting
Proprietary NFC protocol, 128 bit
In passive mode, supply energy is AES accelator and true random
harvested from the active NFC field generator

NGC1081 adds additional sensing interface (ADC/DAC)

NGC1081 a NFC tag-side controller (ARM M0) with integrated connectivity (NFC), actuator (H-Bridge),
sensing (ADC/DAC) and dual power supply modes (passive or battery).

Connectivity Actuation

Integrated H-Bridge (control unit

NFC interface compliant to ISO
and 4 power switches) with drive
14443 type A
current up to 200mA

Dual Operation Mode Sensing

Passive mode (supply energy is 12-bit SAR ADC and 10-bit DAC for
harvested from the active NFC sensing purpose. Integrated
field) or battery supply mode temperature sensor.
(external supply 3.0V...3.3V)
