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.
