NAC1081
Overview
- 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). Main product features are:
- contact-less communication interface NFC - PICC according to ISO/ IEC 14443 Type A - data rate 106 kBit/s - initialization and anti-collision protocol processed in firmware - proprietary and customizable application protocol optimized for end custom applications
- Integrated microcontroller - 32-bit ARM Cortex-M0 CPU operating at clock frequency of 28 MHz - nested vector interrupt controller with 18 interrupts - integrated system tick timer (SysTick) - MicroDMA with 8 DMA channels - 16 kByte integrated ROM containing start-up code and system development kit software library - 16 kByte integrated SRAM - 60 kByte integrated non volatile flash memory - Serial Wire Debug interface - multilayer AHB-Lite on chip interconnect
- Digital Peripherals - Up to 7 programmable and configurable General Purpose Input/ Outputs (GPIO) - System Timer Unit containing six independent timer channels and PWM generator - watchdog timer - arithmetic divide operation hardware accelerator - full duplex
