TMC8670-BI

CoE Servo Drive Controller

The TMC8670-BI goes beyond a standard EtherCAT Slave Controller by integrating a full hardware FOC servo engine, CiA 402 CoE firmware stack and SVPWM generator on one 325-ball BGA device. It runs current, velocity and position control loops entirely on-chip and drives an external gate-driver power stage, while two digital incremental encoder interfaces and Hall feedback support close the loop for demanding industrial servo axes.

Interface Features & Applications

Integrated hardware FOC servo controller runs current, velocity and position loops on-chip, driving an external gate-driver power stage
Built-in EtherCAT Slave Controller and CiA 402 CoE firmware stack remove the need for a separate EtherCAT host MCU
SVPWM space-vector PWM engine and 2 digital incremental encoder interfaces close the servo loop in hardware
On-chip firmware supports field update over EtherCAT or UART without reflashing external memory
Analog and digital Hall plus encoder feedback options cover common industrial servo sensor types
325-ball BGA package and 1.2 V/3.3 V load rails fit compact, high-axis-count servo drive designs

Why Buyers Source TMC8670-BI

TMC8670-BI is best treated as a sourcing-specific line item, not a generic replacement, because exact suffix, package, lifecycle status and traceable supply can affect approval. For overseas buyers, the important confirmation points are stock reality, traceability, packing condition and shipment window. Suited to buyers needing the exact TMC8670-BI ordering code — the CoE EtherCAT servo drive controller with integrated hardware FOC engine in 325-pin BGA (325-TFBGA), 11×11 mm, 0.5 mm pitch — rather than a generic part.

LimChip can confirm current price, date code, packing condition, lot traceability and shipment schedule for TMC8670-BI.
