Automotive Applications
The TC1767 family was designed for real-time automotive control systems and can be found in legacy applications such as:
Engine control units
Transmission control systems
Automotive powertrain electronics
Chassis control
Body control modules
Motor and actuator control
Industrial embedded control systems
Its integrated timers, ADC resources, CAN interfaces and DSP functionality made it suitable for applications requiring deterministic real-time processing.
SAK-TC1767-256F133HR-AD Replacement
Infineon identifies the TC1767 as an end-of-life product and points users toward newer product generations. However, a modern MCU should not be considered a direct pin-to-pin replacement without a complete hardware and software evaluation.
For new automotive designs, Infineon's newer AURIX™ TriCore™ MCU families include TC2x, TC3x and TC4x generations with higher processing capability and more advanced safety and security features.
Migration should consider:
Required CPU performance
Flash and SRAM capacity
CAN and serial interfaces
ADC and timer resources
Package and pin configuration
Functional safety requirements
Existing TriCore software
Automotive qualification requirements
For existing boards where hardware redesign is not practical, original TC1767 inventory may remain the preferred maintenance solution.
