Product details
Overview
TC1784F320F180EPBAKXUMA1 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), and integrated PCP2 peripheral controller running at 180 MHz. It integrates ASC, SSC, MSC, MLI, EBU, and ERAY interfaces for automotive real-time control in engine management and transmission systems.
For engineers reviewing the TC1784F320F180EPBAKXUMA1 datasheet, TC1784F320F180EPBAKXUMA1 pinout, TC1784F320F180EPBAKXUMA1 application, or TC1784F320F180EPBAKXUMA1 equivalent, key selection criteria include real-time interrupt latency (≤2 cycles), on-chip memory partitioning (LDRAM/SPRAM/OVRAM), ERAY_PLL timing compliance, and 16-channel DMA bandwidth allocation across ASC/SSC/EBU peripherals.
Technical Context
The TC1784 implements a dual-core architecture: a TriCore V1.3.1 CPU with 4-stage pipeline and single-precision FPU, plus a dedicated 32-bit Peripheral Control Processor (PCP2) with separate 16 KB PRAM and 32 KB CMEM. Both cores operate synchronously at 180 MHz across full industrial temperature range (–40 °C to +125 °C).
Its bus hierarchy includes a 64-bit local memory bus connecting CPU, PFLASH, and LDRAM; a 32-bit System Peripheral Bus (SPB) linking peripherals; and an LFI bridge enabling coherent access between domains. ERAY interface timing is governed by a dedicated ERAY_PLL with programmable multiplication factor and jitter specification of ±50 ps RMS over 12 kHz–20 MHz bandwidth.

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 |
|---|---|---|---|
| TC1797F320F180EP | Same TriCore V1.3.1 core, 180 MHz, but adds 1 MB additional DFLASH and enhanced ERAY PLL jitter spec (±30 ps RMS) | Targeted for ASIL-D systems requiring higher EEPROM emulation capacity and tighter FlexRay timing margin | Select when extended non-volatile parameter storage and stricter network jitter compliance are required |
| TC275T64F200NAC | TriCore V1.6.1 core, 200 MHz, 4 MB PFLASH, no ERAY-replaces with Ethernet MAC and SENT interface | Suitable for next-gen ADAS domain controllers needing Ethernet backbone connectivity instead of FlexRay | Choose for migration paths requiring Ethernet/IP stack support and higher compute throughput, not FlexRay legacy compatibility |
Compared with TC1797F320F180EP, this part offers lower DFLASH capacity but identical ERAY timing compliance; versus TC275T64F200NAC, it retains FlexRay support at cost of Ethernet capability-making it optimal for established FlexRay-based chassis networks.

FAQ
What is the maximum operating temperature range for TC1784F320F180EPBAKXUMA1?
The device operates across –40 °C to +125 °C ambient temperature, validated per AEC-Q100 Grade 1 qualification. This range covers under-hood ECU environments where junction temperature may reach 150 °C under sustained load, supported by thermal pad design and specified power dissipation limits in the datasheet Section 5.1.5.
Does TC1784F320F180EPBAKXUMA1 support lockstep operation for functional safety?
No-TC1784 does not implement hardware lockstep CPU cores. Functional safety compliance (ASIL-B/C) relies on ECC memory, watchdog supervision, BIST-enabled peripherals, and software-based redundancy techniques documented in Infineon's SafeTcore library and ISO 26262 certification reports for this part number.
Can the PCP2 processor execute code from external memory via the EBU interface?
No-PCP2 executes only from its dedicated 32 KB CMEM or 16 KB PRAM. The EBU interface is accessible exclusively by the main TriCore CPU; PCP2 communicates with external devices through shared memory regions in LDRAM or via mailbox registers mapped in the SPB address space.
Is the BootROM (BROM) field-upgradable or fixed at manufacture?
The 16 KB BootROM is mask-programmed during fabrication and cannot be modified in the field. It contains immutable startup routines, flash programming algorithms, and secure boot loader logic verified by Infineon's ROM signature-ensuring trusted initialization before user firmware execution begins.
