HY-TTC 500 Family

The HY-TTC 500 product family is a high-end electronic control solution designed to satisfy upcoming needs for a wide range of high-end applications in the automotive industry.

It can be used in car prototyping and development as an engineering platform with AUTOSAR standard software as well as a powerful control unit e.g. for powertrain or vehicle dynamic control systems – even in low volume series production.

The extensive I/O set with various configuration options makes the HY-TTC 500 controllers suitable for a wide range of high-end applications: For example, a group of 8 I/O pins can be individually configured for use as voltage output, digital output or analog input. Another use case is to build up a centralized architecture using one HY-TTC 500 controller for the whole vehicle. Commissioning time can be improved by using Ethernet for downloading and debugging purposes.

The freely programmable high-end controllers with a powerful dual-core ARM Cortex®-R4 lockstep processor are protected by a compact, automotive-style housing suited for harsh environments. The controllers fulfill safety requirements of IEC 61508 SIL 2 and EN ISO 13849. They can be programmed either in C or in CODESYS®. The safety certified CODESYS Safety SIL 2 with its validated compiler and code generator speeds up application development significantly.

The majority of run-time tests that are needed to achieve the diagnostic coverage required for ISO 26262 (certifiable up to ASIL C) is performed in hardware by the dual-core lockstep CPU and its safety companion. Therefore almost the full processor power is available for the application. The available memory protection mechanisms allow to execute safety-related and non-safety-related software on the same ECU with freedom from interference. The time-consuming validation of non-safety-related software parts is therefore no longer necessary. Safe data communication is achieved by the standardized software modules (i.e. AUTOSAR E2E-protection or CANopen Safety protocol). In case of a safety-related failure the outputs can be shut off in 3 groups allowing limp-home functionality.

HY-TTC 500 is available in two variants, HY-TTC 540 and HY-TTC 580, with different I/O sets and interfaces to meet the different requirements of OEMs.
