Product details

Overview

TC1767256F133HRADKXUMA1 from Infineon Technologies is a 32-bit TriCore V1.3.1 single-chip microcontroller featuring a 133 MHz super-scalar CPU with integrated FPU, 2 MB program flash, 64 KB data flash (emulating EEPROM), and dual-core architecture combining CPU and PCP2 peripheral control processor. It targets automotive powertrain and chassis control systems requiring deterministic real-time response, high-integrity ADC sampling (32 channels), and CAN-based distributed communication.

For engineers reviewing the TC1767256F133HRADKXUMA1 datasheet, TC1767256F133HRADKXUMA1 pinout, TC1767256F133HRADKXUMA1 application, or TC1767256F133HRADKXUMA1 equivalent, key selection considerations include its 133 MHz full-temperature operation, MultiCAN module with 64 message objects, GPTA/LTCA2 timer subsystem for autonomous I/O management, and hardware-supported safety mechanisms including lockstep-capable peripherals and memory protection units.

Technical Context

The TC1767 integrates two tightly coupled processing units: a TriCore CPU executing real-time control tasks and a dedicated Peripheral Control Processor (PCP2) running at 133 MHz with 8 KB PRAM and 16 KB CMEM for offloading time-critical peripheral handling. Its bus architecture separates 64-bit local memory paths (CPU–Flash–LDRAM) from the 32-bit System Peripheral Bus (SPB), minimizing contention during concurrent memory access and peripheral servicing.

Real-time determinism is enforced via a dual-priority interrupt system supporting 2 × 255 hardware arbitration levels, configurable instruction/data caches (up to 8 KB/4 KB), and on-chip debug support with real-time trace. The MultiCAN controller implements FIFO buffering and gateway functionality across two independent CAN nodes, while the GPTA+LTCA2 subsystem provides hardware-accelerated input capture, PWM generation, and digital signal filtering without CPU intervention.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TC1797256F133HRADKXUMA1	Successor device with TriCore V1.6.2 core, higher 200 MHz max frequency, larger 4 MB PFlash, and enhanced safety features (ASIL-D ready).	Targeted at next-gen ADAS and zonal ECU designs requiring higher compute density and ISO 26262 ASIL-D certification.	Select when new design requires extended safety certification, higher clock headroom, or future-proof memory scalability.
TC275T128F133HRDCXUMA1	Aurix™ TC2xx family part with TriCore V1.6.2, 2 MB PFlash, 256 KB SRAM, and integrated Ethernet MAC; lacks MSC/MLI but adds SENT and PSI5 interfaces.	Suitable for domain controllers integrating body, chassis, and infotainment functions where Ethernet backbone and sensor interface diversity outweigh legacy serial bus needs.	Prefer for mixed-domain applications needing Ethernet connectivity and broader sensor protocol support over MSC/MLI legacy expansion.

Compared with TC1767256F133HRADKXUMA1, the TC1797 offers higher performance and safety readiness but requires toolchain updates, while the TC275 trades MSC/MLI for Ethernet and modern sensor interfaces-making it better suited for scalable domain architectures than legacy powertrain retrofits.

FAQ

What is the maximum junction temperature rating for TC1767256F133HRADKXUMA1?

The TC1767256F133HRADKXUMA1 is rated for operation up to +125°C junction temperature, validated across its full industrial temperature range (−40°C to +125°C). This specification is confirmed in Section 5.1.4 "Operating Conditions" of the official Infineon datasheet V1.4, and applies to all core, memory, and peripheral functions including CPU, PCP2, ADC, and CAN modules.

Does TC1767256F133HRADKXUMA1 support boot-from-flash with secure startup?

Yes-it includes a 16 KB BootROM (BROM) that executes secure startup routines, validates flash integrity via checksum, and supports user-defined boot modes (e.g., flash, emulation, or serial bootloader). The BROM also enforces tuning protection and enables safe field firmware updates without requiring external programming hardware.

Can the GPTA module operate independently of the CPU during sleep modes?

Yes-the GPTA with LTCA2 can run autonomously in low-power modes (e.g., standby or sleep) using its own clock domain. It continues generating PWM waveforms, capturing edge events, and triggering ADC conversions without waking the CPU, reducing system power consumption by up to 35% in duty-cycled motor control applications.

Is TC1767256F133HRADKXUMA1 qualified for automotive AEC-Q100 Grade 1?

Yes-TC1767256F133HRADKXUMA1 is AEC-Q100 qualified for Grade 1 (−40°C to +125°C), as documented in Infineon's official qualification report and referenced in Section 5.4.4 "Quality Declarations" of the datasheet.
