Product details
Overview
TC297TX128F300SBBKXUMA1 from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P super-scalar CPUs, lockstep shadow core for ASIL-D compliance, 8 MB program flash (ECC-protected), 768 KB data flash for EEPROM emulation, and integrated 128-channel DMA. It targets automotive safety-critical powertrain and chassis control systems requiring functional safety up to ISO 26262 ASIL-D.
For engineers reviewing the TC297TX128F300SBBKXUMA1 datasheet, TC297TX128F300SBBKXUMA1 pinout, TC297TX128F300SBBKXUMA1 application, or TC297TX128F300SBBKXUMA1 equivalent, key selection criteria include dual-core lockstep timing integrity, ECC-protected memory hierarchy, ERAY/ETH/ASCLIN interface concurrency, and BGA292 package thermal and routing constraints for automotive ECU designs.
Technical Context
The TC297TX128F300SBBKXUMA1 implements a deterministic real-time architecture with two independent TriCore™ TC1.6P cores operating at up to 300 MHz across -40°C to 125°C, each backed by dedicated 120 KB DSPR and 16 KB PSPR SRAM, plus shared 8 KB DCACHE and 32 KB ICACHE. Core 1 runs in lockstep with its shadow for fault detection.
Its memory subsystem includes 8 MB PFLASH with ECC and write-protection, 768 KB DFLASH with EEPROM emulation capability, and a 32 KB LMU for low-latency access. Communication is enabled via dual ERAY controllers (up to 10 Mbps), 10/100 Ethernet MAC, 12x ASCLIN (UART/SPI/LIN), and QSPI supporting XIP and external memory expansion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC297TX128F300SBBKXUMA2 | Same silicon revision (BC-Step), identical electrical specs, but shipped in tape-and-reel with different top-marking and traceability codes | No functional difference; used interchangeably in production where lot traceability differs | Select for volume procurement requiring alternate packaging or MSL rating documentation |
| TC375LPD128F300SAAKXUMA1 | Successor AURIX™ TC3xx family part with higher clock (330 MHz), larger PFLASH (12 MB), and enhanced crypto engine (AES-256, SHA-256) | Supports next-gen ASIL-D applications requiring cryptographic offload and larger code footprint; not pin-compatible | Choose for new designs needing extended lifecycle, higher performance, or hardware security module integration |
Compared with TC297TX128F300SBBKXUMA1, the MA2 variant offers identical functionality with alternate logistics marking, while the TC375 provides architectural upgrades-higher frequency, expanded memory, and crypto acceleration-but requires PCB redesign due to BGA320 package and revised pinout.

FAQ
What is the maximum ambient temperature rating for continuous operation?
The TC297TX128F300SBBKXUMA1 is rated for continuous operation from −40 °C to +125 °C ambient temperature, validated per JEDEC JESD22-A104. Thermal derating begins above 105 °C case temperature, and junction temperature must remain below 150 °C under worst-case power dissipation conditions defined in Section 3.13 of the datasheet.
Does this MCU support hardware-based cryptographic acceleration?
No-TC297TX128F300SBBKXUMA1 does not include a dedicated hardware crypto engine. It relies on software libraries (e.g., Infineon's OPTIGA™ Trust M integration or AUTOSAR Crypto Stack) executed on its TriCore™ CPUs. Hardware crypto acceleration was introduced in the successor TC3xx family.
Can the Ethernet MAC operate in RMII mode with external PHY?
Yes-the integrated Ethernet MAC supports both MII and RMII physical layer interfaces. RMII mode uses 9 pins (REF_CLK, CRS_DV, RXD[1:0], TXD[1:0], TX_EN, RX_ER) and requires an external 50 MHz reference clock. Configuration is done via ETH_CON register bits and validated in Section 3.28 of the datasheet.
Is the DFLASH truly EEPROM-emulating with byte-level write capability?
Yes-DFLASH supports byte-wise programming and sector-wise erasure (minimum 2 KB sectors), with wear-leveling and error recovery managed by Infineon's Flash Driver Library (FDL). It achieves >100,000 write/erase cycles per sector and retains data for ≥20 years at 125 °C, meeting EEPROM functional equivalence per ISO 26262 Annex D.
