Product details
Overview
SAK-TC297TA-128F300N BC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P CPU cores, lockstep shadow core for ASIL-D safety compliance, 128-channel DMA, 8 MB PFLASH with ECC, and integrated Ethernet MAC (10/100 Mbit/s), E-Ray, and ASC/DSADC peripherals. It targets automotive powertrain and chassis control units requiring functional safety up to ISO 26262 ASIL-D.
For engineers reviewing the SAK-TC297TA-128F300N BC datasheet, SAK-TC297TA-128F300N BC pinout, SAK-TC297TA-128F300N BC application, or SAK-TC297TA-128F300N BC equivalent, key selection criteria include dual-core lockstep timing integrity, on-chip Ethernet PHY interface support, E-Ray bus latency (< 1 µs), DSADC resolution (16-bit with oversampling), and BGA292 package thermal performance (θJA = 24.5 °C/W).
Technical Context
The TC297TA implements a safety-critical dual-core architecture where Core 0 operates as primary and Core 1 as lockstepped shadow, with hardware-assisted comparison logic detecting divergence within one instruction cycle. Its SRI crossbar enables concurrent access to PFLASH, DFLASH, and DSPR across three bus masters.
Real-time determinism is enforced via priority-encoded interrupt controller (ICU) with 256 vector entries, E-Ray controller supporting deterministic time-triggered communication (TTP/C protocol), and HSCT module delivering 1 ns resolution timer capture for engine crankshaft position sensing.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC298B-160F300N DC | Higher pin count (BGA416), adds second Ethernet MAC and extra E-Ray channel; no BGA292 footprint compatibility | Required for multi-gigabit domain gateways needing dual Ethernet ports and triple E-Ray networks | Select when system-level bandwidth exceeds TC297TA's single Ethernet + dual E-Ray capacity |

FAQ
What safety certifications does SAK-TC297TA-128F300N BC support?
SAK-TC297TA-128F300N BC is certified to ISO 26262 ASIL-D at the hardware level, with FMEDA reports, safety manuals, and diagnostic coverage data provided by Infineon. It achieves >99% single-point fault coverage via lockstep core comparison, ECC on all memories, and safe peripheral gating-no external safety monitor required for ASIL-D decomposition.
Does this MCU include an integrated Ethernet PHY?
No, SAK-TC297TA-128F300N BC integrates only the Ethernet MAC layer (MII/RMII interface). An external PHY chip (e.g., LAN8720A or KSZ8081RNA) must be used for physical layer signaling, with precise PCB layout guidelines (length-matched differential pairs, 50 Ω impedance, 100 Ω termination) specified in section 3.28 of the datasheet.
Can the DSADC modules perform simultaneous sampling across multiple channels?
Yes-SAK-TC297TA-128F300N BC supports hardware-synchronized sampling across all four DSADC modules using shared trigger sources (e.g., PWM edge or timer overflow). Each DSADC provides independent filter configuration and result buffering, enabling true simultaneous 16-bit acquisition for multi-phase motor current sensing.
What debug interface does this part use, and is JTAG supported?
SAK-TC297TA-128F300N BC uses Infineon's DAP (Debug Access Port) interface compliant with ARM CoreSight, supporting SWD and JTAG protocols. Debug access is enabled via dedicated TDI/TDO/TCK/TMS pins (BGA292 balls C11–C14), with full support for real-time trace, breakpoint setting, and memory inspection using Lauterbach TRACE32 or iSYSTEM winIDEA tools.
