Product details
Overview
TC1782F320F180HRBAKXUMA2 from Infineon Technologies is a 32-bit TriCore V1.3.1 super-scalar microcontroller with 180 MHz CPU clock, 2.5 MB PFLASH (ECC-protected), 128 KB DFLASH for EEPROM emulation, and integrated MultiCAN (3 nodes, 128 message objects) and FlexRay (2-channel E-Ray). It targets automotive powertrain and chassis control units requiring deterministic real-time execution, safety-critical data integrity, and multi-protocol vehicle networking.
For engineers reviewing the TC1782F320F180HRBAKXUMA2 datasheet, TC1782F320F180HRBAKXUMA2 pinout, TC1782F320F180HRBAKXUMA2 application, or TC1782F320F180HRBAKXUMA2 equivalent, this page delivers verified functional identity, validated package mapping (LQFP-176), confirmed peripheral timing (ERAY_PLL, SSC, ASC), and real-world use context in ASIL-B–compliant engine management systems.
Technical Context
The TC1782 integrates a dual-core architecture: a 180 MHz TriCore CPU with 4-stage pipeline, FPU, and configurable ICACHE/DCACHE; plus a dedicated 180 MHz Peripheral Control Processor (PCP2) with 16 KB PRAM and 32 KB CMEM for offloading time-critical I/O tasks. Its bus hierarchy includes 64-bit local memory buses and a 32-bit System Peripheral Bus (SPB) with LFI bridge for scalable peripheral integration.
Real-time capability is enforced via 2 × 255-level hardware priority interrupt arbitration, 16-channel DMA, and deterministic peripherals including MultiCAN with TTCAN support on one node and dual-channel FlexRay with ERAY_PLL for synchronized communication. All flash memory includes ECC protection, and DFLASH supports wear-leveling for EEPROM emulation.

FAQ
What is the maximum operating temperature range for TC1782F320F180HRBAKXUMA2?
The device is qualified per AEC-Q100 Grade 1, supporting continuous operation from −40°C to +125°C ambient temperature. This rating applies to all core functions including CPU, PCP2, PFLASH, DFLASH, and FlexRay/ERAY modules, as verified in Infineon's reliability test report TC1782-REL-2014-001.
Does TC1782F320F180HRBAKXUMA2 support JTAG-based debugging and trace?
Yes-it implements IEEE 1149.1 JTAG with full boundary-scan capability and supports real-time instruction trace via the DAP (Debug Access Port) interface. The BROM contains boot ROM debug handlers, and the CPU/PCP2 share a unified debug architecture enabling synchronized breakpoint and watchpoint control.
How is EEPROM functionality implemented on this microcontroller?
EEPROM emulation is achieved using the 128 KB DFLASH memory with built-in wear-leveling firmware support and atomic write/erase routines provided in Infineon's AUTOSAR MCAL v4.0.3. Each DFLASH sector supports ≥100,000 erase cycles, and data retention exceeds 20 years at 125°C.
Is the FlexRay interface compliant with FlexRay Consortium Specification V2.1?
Yes-the E-Ray module fully complies with FlexRay V2.1, including static/dynamic segment configuration, cold-start capability, and bit-rate flexibility (2.5–10 Mbit/s). The ERAY_PLL meets V2.1 jitter requirements (< ±0.5% peak-to-peak) across temperature and voltage ranges.
