ISO 14443 Dual-interface Analog Front End


The ISO 14443 Dual-interface Analog Front End (AFE) is a fully integrated analog IP intended for dual-interface (both contact and contactless) Integrated Circuit Card (ICC).


▪ fully compliant with the ISO/IEC 14443 standard and the relevant ISO/IEC 10373-6 tests;
▪ both contact - class A, B & C - and contactless transmission of power;
▪ support both Type A and Type B transmission protocols;
▪ supported bit rates: 106, 212, 424 and 848 kbit/s;
▪ RF front end including the antenna pads, a tuning capacitor, several demodulators, a clock extractor and a load modulator;
▪ dual power manager including a power switch, a voltage regulator, a voltage reference, a variable frequency oscillator, a power-on reset and a supply monitor;
▪ operating junction temperature range: -25°C to +85°C;
▪ straightforward integration through a NFC-WI (ECMA 373) standard interface;
▪ silicon proven in 130 nm and 55 nm CMOS processes;
▪ electrical characteristics of a 55 nm implementation:
− generated core supply voltage (vdd): 1.2 V ±10%;
− generated NVM supply voltage (vdd_nvm): 1.55 V ±5%;
− delivered supply currents up to 7 mA (Ivdd) and 7 mA (Ivdd_nvm);
− typical operating quiescent current of 200 µA;
− maximum standby quiescent current at 25°C smaller than 65 µA.
− silicon area smaller than 0.85 mm².
▪ Type A and Type B digital controllers available separately.


▪ GDSII stream and layer map file;
▪ Library Exchange Format (LEF) file;
