Description

The ST1 is an electronic component model categorized as IC chips. It serves as a hardware/software interface for the Xilinx SPARTANXL XCS40XL-4PQ208C FPGA component used in the STMicroelectronics Contactless System. The FPGA manages communication between the MCU and the Analog Front End, formatting frames according to the ISO 14443 type B standard.

For the physical interface between the FPGA and the MCU, a classic memory interface is used. It includes a bidirectional data bus, selection signal, read/write signal, and a signal for selecting FIFOs or Control/Status registers access. The FPGA logic has been designed with the same accesses for FIFOs and Control Registers, simplifying the interface specification.
