Product details
Overview
TC1791F512F240EPABKXUMA2 from Infineon Technologies is a 32-bit TriCore V1.6 super-scalar microcontroller with 240 MHz CPU clock, 4 MB program flash (ECC-protected), and integrated Peripheral Control Processor (PCP2) operating at 200 MHz. It integrates dual-core real-time control architecture, 128 KB DSPR RAM, and hardware safety features including Safe DMA and lockstep-capable peripherals. Used in automotive powertrain ECUs requiring ASIL-D compliance and deterministic interrupt response.
For engineers reviewing the TC1791F512F240EPABKXUMA2 datasheet, TC1791F512F240EPABKXUMA2 pinout, TC1791F512F240EPABKXUMA2 application, or TC1791F512F240EPABKXUMA2 equivalent, key selection criteria include TriCore+PCP2 dual-execution capability, ERAY/ASC/SSC interface count, flash ECC coverage, and Safe DMA channel allocation for functional safety partitioning.
Technical Context
The TC1791 implements a tightly coupled dual-processor architecture: the main TriCore CPU executes application code with 6-stage pipeline and full IEEE-754 FPU, while the PCP2 handles peripheral offload with dedicated 16 KB PRAM and 32 KB CMEM. Both cores operate across full industrial temperature range (–40°C to +125°C) with independent clock domains synchronized via system bus bridge.
On-chip memory hierarchy includes ECC-protected 4 MB PFLASH, 192 KB DFLASH for EEPROM emulation, and split cache/scratchpad resources-16 KB ICACHE + 32 KB PSPR for instruction, 16 KB DACHE + 128 KB DSPR for data-with configurable cache line locking for real-time determinism.

FAQ
What is the maximum operating temperature range for TC1791F512F240EPABKXUMA2?
The device operates across –40°C to +125°C ambient temperature, validated per AEC-Q100 Grade 1 qualification. All electrical parameters-including 240 MHz CPU frequency, flash read/write timing, and ADC accuracy-are guaranteed over this full range with appropriate thermal design and voltage regulation.
Does TC1791F512F240EPABKXUMA2 support boot-from-flash with secure startup?
Yes. It includes 16 KB BootROM (BROM) with immutable bootloader supporting secure boot via hash verification of PFLASH sectors. The BROM validates signature and checksum before transferring control to user application, meeting UNECE R155 software update security requirements.
How many independent clock domains does TC1791F512F240EPABKXUMA2 implement?
It implements three independent clock domains: CPU domain (up to 240 MHz), PCP2 domain (up to 200 MHz), and peripheral domain (configurable up to 100 MHz). Each domain has dedicated PLLs and gating controls, enabling dynamic power scaling and fault isolation per ISO 26262 requirements.
Is external RAM required for typical TC1791F512F240EPABKXUMA2 deployments?
No. On-chip memory resources-including 128 KB DSPR, 32 KB PSPR, 16 KB DACHE, and 16 KB ICACHE-are sufficient for AUTOSAR OS, application code, and real-time buffers in powertrain ECUs. External RAM is optional only for extended logging or OTA update staging.
