Contactless reader IC

Block diagram

The analog interface handles the modulation and demodulation of the antenna signals for

the contactless interface.

The contactless UART manages the protocol dependency of the contactless interface

settings managed by the host.

The FIFO buffer ensures fast and convenient data transfer between host and the

contactless UART.

The register bank contains the settings for the analog and digital functionality.
