HY-TTC 500 – ECUs for complex control systems
The HY-TTC 500 control units are available in the three variants HY-TTC 510, HY-TTC 540, and HY-TTC 580 to meet the different requirements of OEMs for high-end controllers. The variants differ in regard to the I/O sets and the available interfaces.
The HY-TTC 500 controller from TTControl, a joint venture of TTTech and Hydac can also be ordered via ARADEX when designing the drive train with ARADEX technology.
HY-TTC 500 has the following key features:
- High performance: 32-bit dual-core lockstep CPU, 180 MHz and floating-point unit, 12-bit ADCs
- Comprehensive I/O set with several software configuration options per pin
- Open programming environment C, CODESYS® V3.x and CODESYS® V3.x safety SIL 2
- IEC 61508 (SIL 2) and EN ISO 13849 (PL d), TÜV-tested
- Connectivity: Up to 7 CAN interfaces
- Up to 2.3 MB RAM / 11 MB flash memory

Characteristics of the HY-TTC 500 control (ECU)
The HY-TT 500 control is a control that has been developed for your more complex control requirements and can implement these safely and reliably.
To meet complex control requirements, the HY-TTC 500 control is equipped with a freely programmable high-end controller. The programming can either be done with C or CODESYS®.
As a result of the sturdy automotive aluminum casing, the HY-TTC 500 control is extremely robust and resistant, making it suitable for use in harsh environments.
The present control meets even the most stringent safety requirements. It fulfills safety requirements up to SIL 2 (IEC 61508) / PL d (ISO 13849). Data communication is based on the standardized CANopen® safety protocol (CANopen Safety Master). In the event of a failure relevant to safety, the outputs are switched off in three groups. This allows for a limp-home function that can fall back on emergency strategies in the case of failure, in order to ensure the most important functions even in the event of a fault.
Memory protection mechanisms allow for the failure-free execution of security and non-security software on the same control, which means that the time-consuming validation of insecure software is no longer necessary.
The control features a powerful dual-core ARM Cortex®-R4 lockstep processor as well as a floating-point unit that can handle up to 2.3 MB of RAM / 11 MB of flash memory. The majority of the run-time tests necessary to achieve the diagnostic coverage required for SIL 2 / PL d are performed in the hardware by the dual-core lockstep CPU and its safety attendants. In this way, compared to solutions that implement security measures in software, much more computing power can be used for the application.
The use of Ethernet for downloading and debugging purposes considerably reduces the time required for commissioning.
To meet the different requirements of the OEMs, the control is available in three different versions, each with different I/O sets and interfaces. This results in a comprehensive I/O set with numerous configuration options that cover all requirements.
The control has up to seven CAN interfaces and configurable CAN termination. In addition, the automatic baud rate detection makes connection with your system simple and uncomplicated.
