AX99100A

The AX99100A is a PCIe to Multi I/O (4S, 2S+1P, 2S+SPI, LB) Controller that integrates a single-channel (X1) PCIe 2.0 Gen 1 endpoint controller and PHY with a variety of peripherals such as four high-speed serial ports, one parallel port, high-speed SPI master, I2C master, Local Bus (ISA-Like) and 24 GPIOs. AX99100A supports four modes, namely 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). It is suitable for various I/O interface connectivity applications such as PCIe serial/parallel cards, PCIe data acquisition (DAQ) cards, industrial computers, industrial automation equipment, measurement instrumentation equipment, medical devices, POS terminals and industrial embedded systems.
