Infineon Obsolete TriCore MCU Stock Guide | TC1767, TC1796 & TC1797
Infineon Legacy TriCore MCU Overview
Infineon's TriCore™ architecture combines MCU, RISC and DSP functions in a single processor architecture and has been widely used in automotive powertrain, chassis and real-time control systems.
The TriCore roadmap evolved from early AUDO / AUDO Future products into the newer AURIX™ TC2x, TC3x and TC4x generations. Infineon's current MCU portfolio positions TC3x and TC4x as newer high-performance automotive TriCore platforms.
For older vehicles and industrial systems, however, original TC17xx devices may still be required because replacing the MCU often involves substantial hardware and software redevelopment.

FAQ
What is an Infineon TriCore MCU?
TriCore™ is Infineon's processor architecture combining microcontroller, RISC and DSP functionality. It has been extensively used in automotive real-time control applications.
Is SAK-TC1767-256F133HR-AD discontinued?
Yes. Infineon currently identifies the TC1767 product as END OF LIFE / discontinued.
What is the difference between TC1767 and TC1797?
TC1767 offers 2MB Flash and targets value-oriented applications, while TC1797 provides up to 180MHz performance and 4MB Program Flash, making it better suited to more demanding automotive control systems.
Can AURIX directly replace TC17xx?
No. Although AURIX continues the TriCore architecture, TC2x, TC3x and TC4x devices should not be treated as pin-compatible replacements for legacy AUDO MCUs.
Why buy an obsolete TriCore MCU instead of redesigning?
For legacy automotive and industrial systems, sourcing the original MCU may avoid PCB redesign, firmware migration, qualification and system validation.
