Product details
Overview
TC1782F320F180HRBAKXUMA1 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.
For engineers reviewing the TC1782F320F180HRBAKXUMA1 datasheet, TC1782F320F180HRBAKXUMA1 pinout, TC1782F320F180HRBAKXUMA1 application, or TC1782F320F180HRBAKXUMA1 equivalent, key selection criteria include dual-core timing determinism, on-chip flash ECC coverage, CAN/TTCAN + FlexRay coexistence, and PCP2 peripheral controller support for offloading real-time I/O tasks.
Technical Context
The TC1782 integrates a TriCore V1.3.1 CPU core with 4-stage pipeline and single-precision FPU, plus a dedicated 32-bit Peripheral Control Processor (PCP2) running at 180 MHz with 16 KB PRAM and 32 KB CMEM. Its memory subsystem includes configurable ICACHE (up to 16 KB) and DCACHE (up to 4 KB), alongside 40 KB SPRAM and 8 KB OVRAM for deterministic code/data placement.
Real-time peripheral handling is enabled by a 16-channel DMA controller, 2 × 255-level hardware priority interrupt system, and tightly coupled interfaces: two ASC, three SSC, one MSC, one MLI, MultiCAN (with TTCAN on Node 0), and dual-channel FlexRay (ERAY) with dedicated ERAY_PLL. Power sequencing and reset timing comply with automotive AEC-Q100 Grade 1 requirements (−40°C to +125°C).

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 |
|---|---|---|---|
| TC275T-64F200N AC | TriCore V1.6.2 core, 200 MHz, 4 MB PFLASH, no FlexRay, added Ethernet MAC | Targets ADAS domain controllers requiring TCP/IP stack; lacks FlexRay for x-by-wire | Select when Ethernet connectivity outweighs time-triggered bus needs |
| S32K344 | ARM Cortex-R52 dual-core, 320 MHz, 4 MB flash, CAN FD only, no FlexRay or TTCAN | Focused on body electronics and gateway ECUs; no certified time-triggered communication | Choose for scalable AUTOSAR Classic integration where FlexRay is not mandated |
Compared with TC275T-64F200N AC and S32K344, TC1782F320F180HRBAKXUMA1 uniquely combines FlexRay + TTCAN in a single die with PCP2 offload capability - making it irreplaceable for legacy and new x-by-wire systems requiring ASIL-D compliance without external co-processors.

FAQ
What is the maximum operating frequency of the TC1782F320F180HRBAKXUMA1 CPU core?
The TriCore V1.3.1 CPU core operates at up to 180 MHz across the full industrial temperature range (−40°C to +125°C), verified per AEC-Q100 Grade 1 qualification. This frequency is sustained without derating and supports worst-case execution time (WCET) analysis for ASIL-D software partitions.
Does TC1782F320F180HRBAKXUMA1 support ISO 26262 functional safety certification?
Yes - the TC1782F320F180HRBAKXUMA1 is qualified to ISO 26262 ASIL-D at the hardware level, with built-in safety mechanisms including ECC on all flash memory, lockstep-capable CPU/PCP2 monitoring, and diagnostic libraries provided in Infineon's SafeTcore package.
How many CAN nodes does the MultiCAN module support, and what is the message object capacity?
The MultiCAN module supports exactly three independent CAN nodes, with a total of 128 freely assignable message objects distributed across all nodes. Each node can be configured for standard (11-bit) or extended (29-bit) identifiers, and Node 0 supports TTCAN time synchronization.
Is external RAM required for typical TC1782F320F180HRBAKXUMA1 deployments?
No - the device integrates 128 KB LDRAM, 40 KB SPRAM, and 8 KB OVRAM, sufficient for full AUTOSAR Classic OS, BSW modules, and application code in most powertrain ECUs. External RAM is optional and only needed for large data buffers (e.g., camera preprocessing) beyond internal memory limits.
