1.2. Abstract
The PROFINET Device Chip TPS-1 is designed for easy and cost-efficient implementation of PROFINET interfaces for automation devices. It is a
highly integrated single chip solution that meets all requirements of the PROFINET protocols. The configurable host interfaces facilitate the flexible
realization of different use cases like direct connection of an external host CPU or digital I/Os without additional circuitry.
The TPS-1 complies with PROFINET Conformance Class C. The integrated components realize the complete interface functionality. The internal
structure is designed to fulfill the requirements of the IRT protocol. Special synchronous signals are available to realize all synchronization tasks. To
support line topologies in PROFINET networks, the TPS-1 is equipped with two integrated PHYs and an integrated IRT switch. Time-critical
PROFINET protocols are supported by hardware.
For the complete implementation of a PROFINET device interface, only the TPS-1, a serial Flash device, an oscillator, and the physical adaptations for
the Ethernet interface (transformers and connectors) are needed. The serial Flash component contains the individual chip configuration and firmware
for the PROFINET CPU.
Due to the low space requirement and low power dissipation of the TPS-1, a PROFINET interface can also be integrated into automation devices with
special requirements regarding housing size and protection classes. Conductor routing between the balls is still possible in order to keep down PCB
cost.
