Product details
Overview
SAK-TC275TP-64F200N DC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller featuring three CPU cores (two TC1.6P @ 200 MHz + one TC1.6E @ 200 MHz), 4 MB program flash, 384 KB data flash for EEPROM emulation, and integrated Safety Management Unit (SMU) and Memory Test Unit (MTU). It targets automotive powertrain and chassis control systems requiring ASIL-D compliance.
For engineers reviewing the SAK-TC275TP-64F200N DC datasheet, SAK-TC275TP-64F200N DC pinout, SAK-TC275TP-64F200N DC application, or SAK-TC275TP-64F200N DC equivalent, this device delivers deterministic real-time execution, lockstep core redundancy, ECC-protected memory, and hardware safety monitoring - critical for ISO 26262-compliant engine control units (ECUs), transmission controllers, and brake-by-wire modules.
Technical Context
The TC275TP implements a tri-core architecture with two high-performance super-scalar TriCore CPUs (TC1.6P) and one power-efficient scalar core (TC1.6E), all operating up to 200 MHz across -40°C to 125°C. Each TC1.6P includes dual MAC units, pipelined FPU, 16 KB ICACHE, and 8 KB DCACHE; the TC1.6E provides binary compatibility and 8 KB ICACHE with DRB buffer.
On-chip safety infrastructure includes lockstep shadow cores for both TC1.6P and TC1.6E, SMU-driven alarm handling, MTU for memory initialization and MBIST, and IOM for digital I/O monitoring. All embedded SRAM and NVM are ECC-protected, and the 64-channel DMA supports safe data transfer with channel arbitration and error detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC277TP-64F200N DC | BGA-292 package; adds Ethernet MAC (100BASE-TX), additional ASCLIN and DSADC channels, no LQFP option | Required for designs needing integrated Ethernet PHY interface and higher peripheral density | Select when board space allows BGA and Ethernet connectivity is mandatory for OTA updates or ADAS domain control |
| SAK-TC234LP-32F200N DC | Dual-core only (one TC1.6P + one TC1.6E); 2 MB PFLASH, 192 KB DFLASH; LQFP-144 package | Targeted at cost-sensitive ASIL-B/C applications like HVAC or body control modules | Choose for lower-complexity ECUs where full ASIL-D triple-core redundancy is not required |
Compared with SAK-TC275TP-64F200N DC, the TC277 offers higher integration for domain controllers but sacrifices LQFP accessibility, while the TC234LP reduces safety scope and memory to meet entry-level automotive cost targets - making the TC275 the optimal balance of ASIL-D capability, LQFP manufacturability, and feature set for mainstream powertrain ECUs.
