Kili K400 Secure Processor with integrated NFC controller features a unique, dual-core 32-bit architecture designed to meet FIPS 140-2 level 3 certification.  To maximize the security of payment, security, authentication, and NFC-pairing applications, the cores are separated (CPU and an application CPU.)


The K400 SoC offers the following features:

  • Low power dual-core 32-bit secure architecture designed to meet FIPS 140-2 level 3 certification
  • Small profile Embedded Wafer-Level BGA packaging
  • Proprietary NFC controller with digitally programmable transmitter and sensitive receiver with auto SNR tuning
  • Advanced security features (battery backed-up memory, sudden destruction interface, voltage and temperature monitoring)
  • Integrated USB 2.0 FS device controller and USB HUB with Secure Hub technology
  • Numerous peripheral interfaces ( I2C, SPI, UART, GPIO and SWP)
  • 10-bit analog-digital converter (ADC)
  • Integrated regulators, clock generators, cryptographic accelerators
  • Pre-certified FIPS 140-2 level 3 secure processor when coupled with optional Crypto Calculator firmware module
  • FIPS 140-2 Level 3 compliant
Dashed boxes are not available in all package options

Key Benefits

  •  Saves on bill of material (BOM) costs due to high level of integration
  •   Reduced small form factor as a result of very small real estate usage
  •  Offers the highest security level on silicon
  •   Extends battery life due to power saving modes
  •  Simplifies antenna tuning process due to digitally-tunable antenna
  •  Enables fast time-to-market by eliminating firmware development, porting costs, and lengthy certification process
