Product details
Overview
SAK-TC275TC-64F200W DC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three CPU cores (two TC1.6P super-scalar and one TC1.6E scalar), 4 MB program flash, 384 KB data flash for EEPROM emulation, 200 MHz max clock frequency, and integrated Safety Management Unit (SMU) for ASIL-D automotive safety compliance. It serves as the central real-time controller in engine control units (ECUs), transmission control modules, and battery management systems.
For engineers reviewing the SAK-TC275TC-64F200W DC datasheet, SAK-TC275TC-64F200W DC pinout, SAK-TC275TC-64F200W DC application, or SAK-TC275TC-64F200W DC equivalent, this page delivers verified core architecture details, LQFP176 package mapping, functional safety features, and validated automotive-grade alternatives aligned with ISO 26262 requirements.
Technical Context
The device implements a lockstep-capable triple-core architecture: two TC1.6P cores operate at up to 200 MHz with dual MAC units, pipelined FPU, and separate instruction/data caches (16 KB ICACHE + 8 KB DCACHE); the third TC1.6E core provides binary-compatible low-power execution. All cores share ECC-protected memory subsystems and route through a 64-bit crossbar interconnect (SRI).
On-chip peripherals include four ASCLIN channels with hardware LIN v2.1 support (up to 50 MBaud), 64-channel safety DMA, ERAY high-speed communication interface, Ethernet MAC (MII/RMII), and optional Hardware Security Module (HSM). The SMU monitors CPU, memory, and peripheral faults to generate ASIL-D-compliant error signals.

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-TC277TP-64F200N DC | BGA292 package (vs. LQFP176); adds Ethernet PHY interface and 2× more ASCLIN channels | Preferred for gateway ECUs requiring CAN FD + Ethernet bridging; not pin-compatible | Select when board space allows BGA and Ethernet integration is required |
| SAK-TC234LP-32F200N AC | Dual-core only (one TC1.6P + one TC1.6E); 2 MB PFLASH; no ERAY; lower temp grade (–40 °C to +105 °C) | Targeted at cost-sensitive ADAS domain controllers without time-triggered networking needs | Select for ASIL-B/C applications where ERAY and full ASIL-D SMU coverage are unnecessary |
Compared with SAK-TC275TC-64F200W DC, the TC277 offers higher integration for networked gateways but sacrifices LQFP manufacturability, while the TC234 reduces safety scope and memory to meet entry-level automotive cost targets - neither matches its balanced ASIL-D-ready LQFP176 footprint and triple-core real-time determinism.

FAQ
What is the maximum operating frequency of the SAK-TC275TC-64F200W DC under full temperature range?
The SAK-TC275TC-64F200W DC operates at up to 200 MHz across its full industrial temperature range (–40 °C to +125 °C), verified per the DC-Step specification in the 2019-04 datasheet. This applies to both TC1.6P cores and the TC1.6E core, with PLL configuration enabling stable clock synthesis from the internal 11.5 MHz oscillator or external crystal sources.
Does the SAK-TC275TC-64F200W DC support LIN communication without external transceivers?
Yes - the device integrates four ASCLIN modules with full hardware LIN v2.1 protocol support, including automatic checksum generation, header detection, and slave node response timing. External LIN transceivers (e.g., TLE7259) are still required for physical layer signaling, but all protocol-layer functions run autonomously in hardware.
How is functional safety implemented in the SAK-TC275TC-64F200W DC beyond lockstep cores?
Beyond dual TC1.6P lockstep, safety is enforced via the Safety Management Unit (SMU), which monitors clock stability, memory ECC errors, watchdog timeouts, and peripheral health. The Memory Test Unit (MTU) performs on-the-fly MBIST and ECC initialization, while the Hardware I/O Monitor (IOM) validates digital pin states against expected safety patterns - all meeting ISO 26262 ASIL-D requirements.
Can the SAK-TC275TC-64F200W DC execute secure boot and cryptographic operations natively?
The base SAK-TC275TC-64F200W DC variant does not include the optional Hardware Security Module (HSM); secure boot relies on boot ROM validation and external HSM co-processors. However, HSM-enabled variants (e.g., SAK-TC275T-64F200W DC with "H" suffix) provide AES-128/256, SHA-256, and RSA-2048 acceleration with key isolation and anti-tamper logic.
