AX58100

EtherCAT Slave Controller

1 Introduction

General Description

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. AX58100 supports a

configurable individual function SPI slave interface to enhance SPI slave bandwidth.

The AX58100, in 80-pin LQFP with EPAD, supports the RoHS compliant package and industrial grade operating

temperature range from -40 to 105°C.
