AX99100 is a single-chip solution that fully integrates PCIe 2.0 endpoint controller and SerDes with peripherals, Such as two/four high-speed serial ports, one parallel port, I2C master, high-speed SPI, local bus (ISA-Like) and GPIO. It consists of four main configurations such as 2S (PCIe to Dual Serial), 2S+1P (PCIe to Dual Serial and Single Parallel), 2S+SPI (PCIe to Dual Serial and SPI) and LB (PCIe to Dual Serial and SPI) Local Bus/ISA) - Like) Suitable for different types of applications. AX99100 is packaged in a 68-pin QFN package and is RoHS compliant. It supports commercial-grade operating temperature range from 0 to 70C and industrial-grade temperature range from -40 to 85C. Compatible devices: Serial I/O for serially connected devices, serial network/monitoring equipment, data acquisition systems, POS terminals and industrial PCs, add-in cards Description: PCI Express Single- (X1) PCI Express endpoint with integrated PHY controller Complies with PCI Express card specifications, PCI Express 2.0 PCI Power Management 1.2 compliant Supports legacy and interrupts, ASPM power management -232 serial interface Dual or Quad UART Support -232/-422/-485 multi-protocol Bidirectional speeds up to 25 Mbps per port Full serial modem control Support hardware and software flow control Supports 5, 6, 7, 8 and 9-bit serial formats Supports even, odd, none, space and mark parity Supports custom baud rates via internal PLL or external clock Supports on-chip 256- depth , transmit and receive paths for each serial port Support remote wake and power Management functions Serial transceiver shutdown support Support slow IrDA mode (115200bps) on all serial ports Supports multipoint applications in 9-bit mode Support DMA burst transfer USB, I/O expansion for embedded systems Windows 98SE/Me/NT4.0/2000/XP/Server 2003/Vista/Win 7/Win 8/Win 10, Linux, DOS Material: PCB colour: As shown Package Contents: 1 x AX99100 Pci Express Serial Port Card 1 x Short Iron Piece 1 x CD-Driver Only the above package content, other products are not included.
