Smart Card Chip (Contact Chip with CPU)

This series of smart card chips is a series of contact chip with CPU. As it has a 8 bits CPU core (8051) with interface of both ISO/ICE 7816 and ISO14443-A, the smart card chip is also called dual interface card chip.

Operating Flow
This smart card chip can work in the state of single or dual interface. During single interface operation, our product requires single interface such as contactless or contact interface for power supply and the interface works independently. During dual interface operation, two interfaces supply the power at the same time. The first power-on interface starts working. When it is separated from power, the other interface begins to work.

Workflow of Contact Interface
After the power-on reset of this chip, MCU starts to work and the contact interface keeps receiving data. Through the register, the MCU controls the contact interface for transmitting data. During the process of receiving and sending data, MCU can still keep working.
