FAE Expert Insights
"In my experience supporting industrial automation projects, the FCE1100 has proven to be a reliable and cost-effective alternative to the ET1100. I've successfully helped customers migrate existing designs with minimal effort - in most cases, only the EEPROM configuration needs updating. The chip's compatibility with TwinCAT and other major EtherCAT masters is excellent. I particularly recommend the FCE1100 for servo drive applications where the 125μs cycle time capability is crucial for precise motion control. The external PHY option gives designers flexibility to choose PHYs with specific features like extended temperature range or enhanced ESD protection. For new designs, I suggest using the SPI interface for simpler MCUs or the parallel interface when higher bandwidth is needed."

How do I migrate from ET1100 to FCE1100?
Migration from ET1100 to FCE1100 is straightforward due to pin-to-pin compatibility. Hardware changes are typically not required - the FCE1100 can be soldered directly onto existing ET1100 footprints. Software migration involves updating the ESI (EtherCAT Slave Information) file to reflect the FCE1100 identity information. The EEPROM configuration may need adjustment. Funcience provides migration guides detailing all necessary steps. Most customers complete migration within 1-2 weeks including testing. Funcience offers technical support during the migration process.
Contact LiTong for migration guides and technical support. We can provide sample units for qualification testing.
What external PHY chips are recommended for FCE1100?
FCE1100 works with standard 100BASE-TX Ethernet PHYs. Popular choices include Microchip KSZ8081, Texas Instruments DP83848, and Realtek RTL8201. PHY selection should consider operating temperature range, ESD protection level, and power consumption. For industrial applications, choose industrial-grade PHYs rated for -40°C to +85°C. The PHY interface is standard MII, compatible with most Ethernet PHYs. Funcience reference designs include proven PHY circuits and layout recommendations.
Refer to Funcience reference designs for recommended PHY options. Contact us for specific application requirements.
What is the power consumption of FCE1100?
FCE1100 features low power consumption design suitable for industrial applications. Typical operating current is around 100-150mA at 3.3V supply, depending on traffic and operating conditions. Power consumption scales with EtherCAT cycle time - faster cycle times increase power slightly. The chip includes power management features and can be reset for low-power modes. For thermal design, use the junction-to-ambient thermal resistance specified in the datasheet. Actual power should be measured in your specific application conditions.
Refer to the datasheet for detailed power specifications. Contact us for power analysis in your specific application.
Does FCE1100 support distributed clocks?
Yes, FCE1100 fully supports the EtherCAT distributed clock (DC) feature. Distributed clocks enable precise synchronization of multiple slave devices with jitter in the nanosecond range. This is essential for applications requiring coordinated multi-axis motion control. The DC feature is implemented in hardware and requires proper configuration in the ESI file. When using distributed clocks, the propagation delay through each slave is automatically compensated. Funcience provides application notes on DC configuration and best practices for achieving optimal synchronization performance.
