Contactless reader IC
6. 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.
