AX99100

The AX99100 is a single chip solution that fully integrates PCIe 2.0 Gen 1 end-point controller and SerDes with a variety of peripherals such as four High Speed Serial Ports, one Parallel Port, I²C Master, High Speed SPI, Local Bus (ISA-Like) , and GPIOs. It consists of four main configurations such as 4S (PCIe to Quad Serial), 2S+1P (PCIe to Dual Serial and Single Parallel), 2S+SPI (PCIe to Dual Serial and SPI), and LB (PCIe to Local Bus/ISA-Like) for different kinds of applications.
