The Multi-Protocol Synchronous Serial Engine IP integrates basic serial interface protocols like UART, SPI, and I2C into a single AXI interface port. The individual modules for these protocols have been implemented in a ruggedized form to avoid bus errors due to interfering noise from various sources thus making it suitable for application in automobile electronics.
AXI4-Lite standard user interface. Connects as a 32-bit slave on AXI interface
Ruggedized SPI, I2C, and UART interface
User-configurable number and type of interfaces through a configuration tool
User-configurable parameters of each interface like baud rate/ datarate, modes, length of transmission, etc.
Supports master and slave modes for SPI and I2C interfaces
Configurable number of slaves on SPI interface
Contains hardware FIFO for UART, SPI, and I2C interfaces with configurable depth up to 1024 words
