1 Product Features
TMC8462 is an advanced EtherCAT Slave Controller device used for EtherCAT communication. It provides
the interface for data exchange between EtherCAT master and the slave’s local application controller. In
addition, TMC8462 provides complex IO functions paired with high voltage features and integrated 100Bit
Ethernet PHYs.
Advantages:
• Fully standard compliant and proven EtherCAT engine
• Highly integrated with highest feature count vs. package size
• License-free & royalty-free
• High Voltage & robust
• Saves board space & reduces BOM
• Long-term availability
Major Features:
•
•
EtherCAT Slave Controller with 2 ports for bus interfacing, 8 FMMU & 8 Sync Managers, Distributed
clocks with 64 bit, 16KByte of Process Data Memory, external I2C EEPROM, SPI Process Data Interface
(PDI), optional device emulation
TRINAMIC Multi-Function Control and IO block with 24 configurable IO ports for complex real-time IO
