8010C
The 73S8010C is a single smart card interface IC, compliant to the electrical requirements of ISO-7816-3 and EMV 4.0 electrical specifications. It implements an I²C bus control, making it particularly suitable for applications that require several card interfaces. This is applicable to multiple SIM/SAM (Secure Access Module) configurations in Point-of-Sale and payment terminals. The I2C host interface is advantageous requiring fewer controller interface signals. The 73S8010C can also be used in conjunction with any host microcontroller that can support the smart card protocol layer. The 73S8010C differentiates itself from in smart card power supply generation by using an inductor-based DC-DC converter.Features
