Connecting Embedded Systems
ASIX is a Leading Fabless Semiconductor Company for Embedded Networking/Bridging Solutions
There is a growing need to add network connectivity into every embedded system. According to the projection from Forrester, by year 2020, the global thing-to-thing Internet business and the current people-to-people Internet business would reach a ratio of 30:1. IOT will realize large-scale popularity and will be developed into a trillion-US-Dollar industry. In other words, the network connectivity of Machine-to-Machine (M2M) or Internet of Things (IOT) communications will be the primary market demand for the embedded networking system for the years to come.
The Ethernet's ease of use, cost effectiveness, high bandwidth, stability, security, and high degree of compatibility make it a natural solution for accessing the Internet. In addition to SOHO and corporate networks, the Ethernet is gradually making its way into consumer and household devices as a primary way to access the Internet, thus providing both the stability and reliability demanded by industrial users and the bandwidth and multimedia connectivity demanded by home consumers.
ASIX Electronics is a leading fabless semiconductor supplier with a focus on networking, communication, and connectivity applications. ASIX was founded in May 1995 in Hsinchu Science Park, Taiwan, and has been listed on Taiwan OTC Stock Exchange (TAIEX code 3169) since November 2009. ASIX Electronics specializes in network & I/O connectivity solutions and provides embedded bridge silicon products such as non-PCI Ethernet controllers, USB-to-LAN controllers, Network SoC and PCIe/PCI/USB Bridge Controllers.

Embedded Ethernet
This solution targets devices with micro-controller, which comes without PCI bus interface, but with a non-PCI or SRAM type interface. In this case, the highly integrated Non-PCI bus Ethernet MAC+PHY controller is used to connect these devices to Ethernet. This solution provides the easiest way to connect the embedded system to the network for the reason that majority of the micro-controller all support Non-PCI local bus interface. Engineers are able to design very-low-cost, and yet high-performance embedded systems, which offer remote access capabilities in addition to Internet connectivity. This solution is suitable for home appliances, factory/building automation, industrial equipment, security systems, remote control/monitoring/management, streaming media, and multimedia networking. In addition, for broadband applications such as POS terminals, WLAN AP, broadband routers, VoIP, content distribution, IP STB, IP cameras, digital video recorders, DVD recorders/players, high-definition TV (HDTV), digital media adapters, game consoles, home gateways, and IPTV, this solution can also be attractive and cost effective.

SuperSpeed USB-to-LAN
This solution targets microcontrollers that already have a USB host interface embedded. In this case, an internal or external USB-to-LAN controller can be used to connect these devices to the Ethement
The so-called USB-to-LAN approach converts an USB 2.0/3.0 signal to the Fast Ethernet/Gigabit Ethernet interface through an USB-to-LAN controller used in the cradle or docking station for the mobile devices. Because the USB 2.0/3.0 uses a compact four/nine-pin connector, this solution reduces many of the pin-out connections between the cradle/docking station and the mobile devices. Another, more flexible way is to use an external USB-to-LAN dongle to connect the mobile devices to the network if the microcontroller within the devices has a built-in USB host interface. This will leverage the SuperSpeed and serial bus characteristic of USB 3.0, to improve the performance of the devices.
This solution is suitable for computer peripherals, handheld devices, home electronics and appliances, streaming media, broadband media, and other consumer electronics such as for Notebooks/MIDs/UMPCs/Tablet PCs, ultrabooks, USB to Ethernet dongles, cradles/port replicators/docking stations, game consoles, digital-home appliances, and any embedded system using a standard USB port.

Embedded Network SoC
This solution is those micro-controllers, which already integrate both Ethernet and Wi-Fi Connectivities, the so-called single chip SoC solution. The AX110xx family is the world's first high-performance 8-bit microcontroller to deliver the 10/100Mbps Fast Ethernet MAC/PHY, the TCP/IP accelerator, and the flash memory in a single chip. With this highly integrated system-on-a-chip solution, the AX110xx family provides a very small form-factor solution to enable embedded system designers to design compact, low-power, high-performance, yet low-cost, embedded and industrial Ethernet applications for the growing embedded networking markets.

The AX22001 is a single chip micro-controller with TCP/IP and 802.11 WLAN MAC/baseband. Leveraging prevalent Wi-Fi infrastructure in home and office environment, the new single-chip Wi-Fi SoC, AX22001, provides cost competitive wireless connectivity solution for bridging uncompressed digital audio data, compressed digital video data and serial/parallel user data through its versatile interfaces over the Wi-Fi network. This solution makes the devices very compact, and is suitable for home appliances, factory/building automation, industrial equipments, security systems, remote control/monitoring/management, and streaming media applications such as Wi-Fi speakers, iPhone-controlled toys, POS terminals, vending machines, IP camera, Internet radio, automatic meter reading, environmental monitoring systems, network sensors, networked UPS, Serial to Ethernet/Wi-Fi adapters, and Ethernet/Wi-Fi to ZigBee bridges, Ethernet to Wi-Fi bridges, can also find this solution quite attractive in cost, space, and power consumption-wise.

I/O Connectivity
In August 2011, ASIX acquired the business line of I/O connectivity, including all assets and intellectual property rights, from India-based MosChip Semiconductor Technology Ltd. The acquisition enhances ASIX's portfolio of embedded networking and connectivity products by adding single, multi-port Serial, Parallel, Ethernet, USB Host, ISA and IrDA connectivity for various computer and peripheral equipment with PCI Express (PCIe), Peripheral Component Interconnect (PCI) and USB host interface.
The I/O connectivity products include three series: MCS99xx PCIe bridge controllers, MCS98xx PCI bridge controllers and MCS78xx/MCS77xx USB bridge controllers. For chip-to-chip or system-to-system connections, these controllers provide cost effective, standards compliant, and high-performance embedded system applications, such as remote access servers, storage network management, data acquisition systems, point-of-sale (POS) terminals, handheld devices, set-top box, digital TVs, industrial control and building automation equipment.
The PCIe bridge series, MCS99xx, provide a single-chip, PCI Express x1 (single-lane) to a peripheral controller with support for single and multi-port Serial, Parallel and USB interfaces. PCIe is an interconnection system based on the PCI standard connecting a microprocessor to attached devices for high-speed operation. The electrical and mechanical interfaces of PCIe are not compatible with the PCI bus interface. This bus also provides a high-speed 2.5GBs data rate.

The PCI bridge series, MCS98xx, provide OEMs low cost solutions for developing products that bring single and multi-port Parallel, Serial and ISA devices to the market place. PCI is an interconnection system between a microprocessor and attached devices. The MCS98xx supports 3.3/5V PCI bus signaling specifications at full 33 MHz clock speed and allows direct interface to the system bus, delivering a significant reduction in board space requirements.
