Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC1762F133F133HLXUMA1 | TriCore v1.6 core, 133 MHz max, 2 MB flash, 128 KB RAM, enhanced safety features (lockstep, ECC on all memories) | Targeted for ASIL-D systems requiring higher compute throughput and functional safety certification evidence | Select when migrating to next-gen powertrain platforms needing >100 DMIPS and ISO 26262 ASIL-D compliance support |
| TC275T128F133NACXUMA1 | AURIX™ TC2xx family, TriCore v1.8, 200 MHz, 2 MB flash, 512 KB RAM, integrated HSM, Ethernet MAC | Designed for zonal architectures with Ethernet backbone, OTA update capability, and hardware security module | Choose for new designs requiring AUTOSAR Adaptive support, secure boot, and multi-gigabit communication bandwidth |
Compared with TC1762 and TC275, FT1161128F66HLAAXP offers proven cost-optimized implementation for established ASIL-B ECUs, while lacking lockstep cores and Ethernet - making it ideal for volume production where functional safety requirements stop at ASIL-B and CAN remains the primary bus.

FAQ
What is the maximum operating frequency and temperature range for FT1161128F66HLAAXP?
The FT1161128F66HLAAXP operates at up to 66 MHz across the full industrial temperature range of −40°C to +85°C. This rating is validated per Infineon's Preliminary Data Sheet V1.0 (April 2008), with thermal resistance junction-to-leads specified at 29 K/W for the PG-LQFP-176-2 package.
Does FT1161128F66HLAAXP support CAN FD or only classical CAN?
FT1161128F66HLAAXP supports only classical CAN (ISO 11898-2) at up to 1 Mbps via its MultiCAN module. It does not implement CAN FD protocol features such as flexible data-rate or extended data length - those capabilities were introduced in later AURIX™ generations like TC2xx.
Is there on-chip debug support, and what level is implemented?
Yes, FT1161128F66HLAAXP includes on-chip debug support compliant with OCDS Level 1 (CPU state) and Level 2 (CPU + DMA transfers). Debug access uses standard JTAG (TRST/TCK/TMS/TDI/TDO) and enables real-time trace, breakpoint setting, and register inspection during development and validation.
What are the supported boot sources for this microcontroller?
The FT1161128F66HLAAXP supports booting from internal program flash (default), external memory via FPI bus, or serial interfaces including ASC and MSC. Boot mode is selected by configuration pins (BOOT0–BOOT2) at reset, with boot ROM containing initialization code and flash programming routines.
