Product details
Overview
SAK-TC297TP-96F300N BC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring dual 300 MHz TC1.6P super-scalar CPU cores, lockstep shadow core for ASIL-D compliance, 4 MB program flash (PFLASH), 768 KB data flash (DFLASH) with EEPROM emulation, and integrated Ethernet MAC, E-Ray, and ASC/DSADC peripherals. It targets automotive safety-critical applications including electric powertrain control and ADAS domain controllers.
For engineers reviewing the SAK-TC297TP-96F300N BC datasheet, SAK-TC297TP-96F300N BC pinout, SAK-TC297TP-96F300N BC application, or SAK-TC297TP-96F300N BC equivalent, key selection criteria include dual-core lockstep timing integrity, ECC-protected memory hierarchy, functional safety certification (ISO 26262 ASIL-D), Ethernet and E-Ray interface support, and BGA292 package thermal/mechanical constraints.
Technical Context
The TC297TP implements a deterministic real-time architecture with two independent TriCore TC1.6P CPUs operating at up to 300 MHz across -40°C to 125°C ambient, each backed by dedicated 120 KB DSPR and 16 KB PSPR SRAM, plus shared 64-bit SRI crossbar enabling concurrent access to PFLASH, DFLASH, and peripheral registers. The lockstep shadow core validates instruction execution cycle-by-cycle for fault detection.
On-chip safety mechanisms include ECC on all embedded memories (PFLASH, DFLASH, SRAM), parity-checked DMA channels, safe interrupt controller with error injection test mode, and hardware-based end-to-end data path protection for ADC and communication interfaces (E-Ray, ETH). The device supports AUTOSAR OS and SafeTcore RTOS environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive safety microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC297TP-96F250N BC | 250 MHz CPU frequency, 3 MB PFLASH, same BGA292 package and safety features. | Lower computational throughput; suitable for cost-sensitive ADAS cameras or non-torque-critical chassis modules. | Select when peak MIPS requirement is ≤ 1,800 and flash storage needs are <3 MB. |
| SAK-TC397XP-160F300N DC | TriCore v1.8P core, 300 MHz, 8 MB PFLASH, BGA352 package, includes HSM security module. | Supports post-quantum cryptography and secure over-the-air updates; required for Zonal E/E architectures with centralized security policy enforcement. | Choose for next-gen vehicle platforms requiring Common Criteria EAL5+ certified hardware security and >4 MB code space. |
Compared with SAK-TC297TP-96F300N BC, the 250 MHz variant trades clock speed for lower dynamic power and cost in less compute-intensive safety domains, while the TC397XP adds hardware security and memory capacity for zonal gateway roles-neither is pin-compatible, requiring PCB redesign.

FAQ
What is the maximum junction temperature rating for SAK-TC297TP-96F300N BC?
The device is rated for maximum junction temperature of +150°C per AEC-Q100 Grade 1 qualification. This allows operation in under-hood environments up to +125°C ambient when mounted on a 4-layer PCB with 2 oz copper and thermal vias beneath the BGA292 thermal pad. Thermal derating curves are provided in Section 3.4 of the datasheet.
Does SAK-TC297TP-96F300N BC support hardware virtualization for AUTOSAR Adaptive?
No. The TC297TP implements TriCore v1.6P architecture without MMU or hypervisor extensions. It supports AUTOSAR Classic only, with fixed memory partitions and static scheduling. For AUTOSAR Adaptive, Infineon recommends the TC3xx family with ARM Cortex-R52 cores and virtualization support.
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 10 pins (TX_EN, TXD[1:0], RXD[1:0], CRS_DV, REF_CLK, RX_ER, COL, TX_ER) and requires an external 50 MHz reference clock. Timing parameters are specified in Section 3.28.4 of the datasheet.
How is the lockstep core monitored for fault detection?
Fault detection occurs via hardware comparator that validates identical instruction fetch, decode, and execution results between primary and shadow cores every cycle. Mismatch triggers immediate trap exception, disables outputs, and asserts ERRN pin. Diagnostic coverage exceeds 99% for permanent faults per ISO 26262 FMEDA report.
