General Description

The TMC8100 is a dedicated serial protocol converter

IC, especially for absolute encoder bus protocols. It

operates as a bus controller for these protocols and as

a peripheral with either a serial peripheral interface (SPI)

or universal asynchronous receiver-transmitter (UART)

interface connection to the attached

microcontroller/motion controller delivering the extracted

and adjusted encoder position information.

It integrates a programmable high performance serial

communication engine for synchronous and

asynchronous data up-to 16Mb/s. In addition to a clock

generator, several counter/timer units, a programmable

CRC generator and direct I/Os for connecting bus

transceivers, standard SPI, 2x UART, and I2C interfaces

are available.
