To ensure stable power supply voltage, please ensure that enough power supply
filtering capacitors are available in the system to absorb kinetic energy during
deceleration and load control. Additional a regulated power supply is
recommended, especially if the system is operated close to the maximum supply
voltage or a long power supply line is used.
For power supply filtering capacitor value, the following rule of thumb can
be used to calculate the system capacity (depending on the motor velocity

i To reduce power losses in the capacitors and increase voltage stability use
low ESR-capacitor type.
4.6 Interface
The TMCC160 system in a package supports RS232, RS485, CAN and SPI interface as well as an
analog input which can be used for control and parameterization.
For easy intercommunication with a microcontroller or a host PC TMCC160
system in a package provides a 3.3V UART interface which can be directly
connected to a microcontroller UART (3.3V TTL level) or connected to an external
RS232 transceiver supporting a full RS232 signal interface.
