The logiUART is the logicBRICKS single-channel programmable UART, which enables automotive Electronic Control units (ECUs) to communicate within the vehicle's body through the Local Interconnect Network (LIN). In order to support the LIN protocol, the logiUART IP core implements an optionally software driven TX signal - "break" signal, as well as the "beak error detection. Due to the small IP core's size, even the smallest FPGA devices can accommodate multiple LIN network nodes by using multiple logiUART instances.

It offers simplicity in use and high overall performances. Communication speeds are supported in a wide range, starting from a few bps up to 3 Mbps. Available separated TX and RX FIFOs reduce the CPU overhead. Readable FIFO's pointers with supported interrupts allow flexible software control. Various character formats are supported. Different types of parity protection and framing errors are automatically supported too. The logiUART is a real plug-and-play IP core, supported by the AMD Vivado™ Design Suite.
