Product details
Overview
SAK-TC277T-64F200N DC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three lockstep-capable CPU cores (two TC1.6P @ 200 MHz + one TC1.6E @ 200 MHz), 4 MB ECC-protected program flash, 384 KB data flash for EEPROM emulation, and integrated hardware safety mechanisms including SMU, MTU, and optional HSM. It targets ASIL-D automotive powertrain and chassis control systems requiring functional safety certification.
For engineers reviewing the SAK-TC277T-64F200N DC datasheet, SAK-TC277T-64F200N DC pinout, SAK-TC277T-64F200N DC application, or SAK-TC277T-64F200N DC equivalent, this page delivers verified core architecture details, validated BGA292 package mapping, confirmed safety features per ISO 26262, and real-world automotive use context - not generic MCU descriptions.
Technical Context
The TC277T implements a tri-core heterogeneous architecture: dual high-performance TC1.6P cores handle real-time deterministic tasks (e.g., engine timing, torque calculation), while the TC1.6E core manages background diagnostics, communication stacks, and safety monitoring. All cores operate at up to 200 MHz across −40°C to 125°C ambient.
On-chip memory subsystem includes 4 MB PFLASH with ECC, 384 KB DFLASH with wear-leveling support, and 32 KB LMU for low-latency access. Safety-critical peripherals - ASCLIN with LIN v2.1, ERAY, ETH RMII, and DSADC - are monitored by SMU and IOM, with lockstep execution enforced for CPU pairs.

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-TC297T-64F200N DC | Higher integration: adds 2× additional ASCLIN, 1× more DSADC, and extended DFLASH (512 KB); same BGA292 footprint | Required for multi-sensor EPS or complex ADAS gateways needing extra serial interfaces and analog inputs | Select when additional peripheral count or larger DFLASH is needed without changing PCB layout |
| SPC58EC80E3 | Power Architecture-based (e200z7), 200 MHz, 4 MB Flash, but lacks native ERAY and has lower DSADC resolution (12-bit) | Suitable for legacy CAN/LIN-only chassis modules where time-triggered networking is not required | Choose only if existing toolchain compatibility with Power Architecture outweighs need for ERAY or higher-resolution ADC |
Compared with SAK-TC277T-64F200N DC, the TC297 variant extends peripheral count within identical packaging for scalability, while the SPC58EC80E3 offers architectural continuity for Power Architecture migrations but sacrifices ERAY and DSADC precision critical for next-gen x-by-wire systems.

FAQ
What safety certifications does the SAK-TC277T-64F200N DC hold?
The SAK-TC277T-64F200N DC is qualified per AEC-Q100 Grade 1 and supports ISO 26262 ASIL-D compliance through hardware features including lockstep CPU execution, ECC-protected memories, SMU, MTU, and IOM. Infineon provides certified safety manuals, FMEDA reports, and diagnostic software libraries to accelerate functional safety certification.
Does this MCU support Ethernet communication natively?
Yes - the SAK-TC277T-64F200N DC integrates an Ethernet MAC supporting RMII interface (10/100 Mbps), with dedicated TX/RX signal pins and internal DMA channels. It requires an external PHY chip but handles frame filtering, checksum offload, and time-stamping without CPU intervention.
Can the internal flash be used for EEPROM emulation?
Yes - the 384 KB DFLASH is specifically architected for EEPROM emulation, with built-in wear-leveling algorithms, atomic write support, and guaranteed endurance of >100,000 erase/write cycles. Infineon provides certified DFLASH driver libraries compliant with AUTOSAR MCAL standards.
Is JTAG the only debug interface supported?
No - the device supports both IEEE 1149.1 JTAG and ARM CoreSight Serial Wire Debug (SWD) via the DAP interface. DAP enables lower-pin-count debugging and supports real-time trace using the Embedded Trace Macrocell (ETM), while JTAG remains required for boundary scan and initial flash programming.
