Not sure if products are available yet or if this is just based on the announcement of an upcoming product.

I thought it was interesting since it's RISC-V in hardware from a classic/respected/well-established US-based company, which is not so common yet. Also it's "real" CPU cores even though they share a SoC with FPGA circuitry; this is not RISC-V cores being implemented on the FPGA fabric.

It's really "cores" and not "core", too: the SoC features one RV64IMAC core for monitoring (and probably hard real-time tasks) and a quad-core RV64GC for general computing/applications I guess. It uses DDR4 memory so it's quite beefy for an embedded target.
