Product details
Overview
SAK-TC297TP-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, 8 MB program flash with ECC, 768 KB data flash for EEPROM emulation, and integrated 128-channel DMA. It targets automotive powertrain and chassis control systems requiring functional safety up to ISO 26262 ASIL-D.
For engineers reviewing the SAK-TC297TP-128F300N BC datasheet, SAK-TC297TP-128F300N BC pinout, SAK-TC297TP-128F300N BC application, or SAK-TC297TP-128F300N BC equivalent, key selection criteria include dual-core lockstep timing integrity, ERAY/ETH/ASCLIN interface coexistence, flash ECC coverage depth, and BGA292 thermal performance under 125°C ambient.
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, each backed by dedicated instruction/data caches (ICACHE/DCACHE), scratchpad RAM (DSPR/PSPR), and hardware-assisted floating-point units. The lockstep shadow core continuously verifies primary core execution at cycle level.
On-chip memory subsystem includes 8 MB PFLASH with full ECC protection, 768 KB DFLASH supporting wear-leveling and EEPROM emulation, and 32 KB LMU for low-latency data access. Peripheral interconnect uses a 64-bit SRI crossbar enabling concurrent CPU, DMA, and peripheral access without arbitration stalls.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC298TP-128F300N BC | 416-pin BGA package; adds third TriCore CPU core and 16 MB PFLASH; higher thermal envelope (15 × 15 mm → 17 × 17 mm) | Required for multi-domain ECU consolidation (e.g., combining powertrain + chassis functions) | Select when additional compute headroom or memory capacity exceeds TC297TP's 8 MB flash and dual-core limit |
| SAK-TC275TP-64F200N DC | Single-core TC1.6P @ 200 MHz; 4 MB PFLASH; BGA196 package; DC-step (not BC); lower ASIL-D verification scope | Suitable for cost-sensitive ASIL-B/C applications like body control modules or HVAC controllers | Select when functional safety requirements are ASIL-B/C and real-time throughput needs are ≤60% of TC297TP capability |
Compared with SAK-TC297TP-128F300N BC, the TC298TP offers higher integration for domain controllers but increases PCB area and thermal management complexity, while the TC275TP reduces cost and footprint at the expense of ASIL-D certification completeness and dual-core determinism.

FAQ
What is the maximum junction temperature specification for SAK-TC297TP-128F300N BC?
The device is rated for continuous operation at junction temperatures from –40°C to +125°C, validated per AEC-Q100 Grade 1 qualification. Thermal design must maintain Tj ≤ 125°C under worst-case power dissipation (2.8 W typical at 300 MHz, full peripheral activation, 125°C ambient).
Does SAK-TC297TP-128F300N BC support JTAG debugging in production environments?
Yes - it supports IEEE 1149.1 JTAG boundary-scan and debug access port (DAP) with secure authentication. Production units allow full debug access only when DEBUG_ENABLE fuse is unblown; post-fuse-blown units restrict JTAG to read-only memory inspection and basic reset control.
How is EEPROM emulation implemented in the 768 KB DFLASH?
Infineon's MemTool software library manages wear leveling, atomic page updates, and error recovery across DFLASH sectors. Each emulated EEPROM byte maps to a 256-byte physical sector; guaranteed endurance is 100,000 write cycles per logical address with built-in bad-block remapping.
Can SAK-TC297TP-128F300N BC operate with a single 3.3 V supply?
No - it requires three independent supplies: 1.3 V for core logic, 3.3 V for I/Os and analog peripherals, and 5.0 V for certain high-drive GPIOs and external flash interfaces. The EVR (Embedded Voltage Regulator) only generates 1.3 V; external regulators must supply 3.3 V and 5.0 V rails.
