ASIX Electronics Corporation Notice USB to LAN products 
Dear Customer:

If you got some problems on ASIX USB to LAN products, please download the How to identify authentic ASIX USB to LAN Products document to double check if your USB to LAN device includes an Non-authentic ASIX USB to LAN solution inside or not? If yes, please contact the manufacturer of your USB to LAN device to get proper drivers instead. ASIX DOES NOT GUARANTEE AND PROVIDE ANY SUPPORT FOR THOSE NON-AUTHENTIC ASIX PRODUCTS.

  Yes, I understand.

 AX58100 -- 2/3-Port EtherCAT Slave Controller (ESC) with 2 Embedded PHYs

The AX58100 is a 2/3-port EtherCAT Slave Controller (ESC), licensed from Beckhoff Automation, with two integrated Fast Ethernet PHYs which support 100Mbps full-duplex operation and HP Auto-MDIX. The AX58100 supports the CANopen over EtherCAT (CoE), File Access over EtherCAT (FoE), Vendor Specific-protocol over EtherCAT (VoE), etc. standard EtherCAT protocols and provides a cost-effective solution for industrial automation, motion/motor/digital I/O control, Digital to Analog (DAC)/Analog to Digital (ADC) converters control, sensors data acquisition, robotics, etc. industrial fieldbus applications.

The AX58100 provides either a three-channel PWM controller or a Step/Direction controller, and an Increment/Hall encoder interface for closed-loop motor control; a SPI master controller for DAC/ADC converter control and sensors data acquisition; 32 DIOs for industrial I/O control and an I/O watchdog for functional safety.

The AX58100 provides two Process Data Interfaces (PDI), SPI slave and Local bus, support the connection with most popular MCU and DSP on those traditional non-EtherCAT fieldbus applications. The AX58100 provides two memory spaces, ESC and Function, designers can use chip select to decide to access which one. The bridge will synchronize two memory spaces’ contents for EtherCAT Master to remotely control AX58100 functions (PWM, SPI master etc.). The AX58100 reports the ESC and Functions interrupt events to interrupt status registers and supports level or edge interrupt trigger mode to inform external MCU/DSP to manage these ESC and Functions interrupt events.

The AX58100, in 80-pin LQFP with EPAD, supports the RoHS compliant package and industrial grade operating temperature range from -40 to 105°C
