It targets automotive safety-critical applications including electric powertrain control and brake-by-wire systems.
For engineers reviewing the SAK-TC265DC-40F200W BC datasheet, SAK-TC265DC-40F200W BC pinout, SAK-TC265DC-40F200W BC application, or SAK-TC265DC-40F200W BC equivalent, this page delivers verified technical context, LQFP176 package mapping, dual-core timing architecture, functional safety features, and real-world automotive use cases - all derived from Infineon's official TC265 data sheet (V1.0, 2017-06).
Technical Context
The TC265 implements lockstep execution between its TC1.6P core and shadow core to meet ISO 26262 ASIL-D requirements. Its 64-bit SRI crossbar enables concurrent access to PFLASH, DFLASH, and SRAM resources while maintaining ECC protection across all on-chip memories.
It integrates dedicated safety peripherals including SMU, end-to-end CRC units, memory BIST, and configurable watchdog timers. The device supports dual-voltage I/O (5 V / 3.3 V switchable), includes ERAY and Ethernet MAC interfaces, and provides 48-channel DMA with safe transfer arbitration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-core automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC264T-40F200W BC | LQFP144 package; reduced peripheral set (no Ethernet MAC, fewer ASCLIN channels, no QSPI) | Suitable for cost-sensitive ADAS sensor fusion ECUs where Ethernet connectivity is unnecessary | Select when board space and BOM cost constrain require smaller footprint and lower peripheral count |
| SAK-TC267B-40F200W BC | BGA292 package; adds dual Ethernet PHY support, higher PFLASH (4 MB), and extended DSADC channel count | Targeted at high-end central gateways requiring multi-gigabit backhaul and secure boot acceleration | Select when system demands >2 Ethernet ports, larger code storage, or advanced cryptographic acceleration not present in TC265 |
Compared with SAK-TC264T, the TC265 adds Ethernet and QSPI for domain controller scalability; compared with TC267B, it trades BGA density and dual Ethernet for LQFP manufacturability and cost efficiency - making it the optimal balance for mid-tier automotive safety ECUs.

FAQ
What is the maximum operating frequency of the TC1.6P core in SAK-TC265DC-40F200W BC?
The TC1.6P core operates at up to 200 MHz across the full industrial temperature range (−40 °C to +125 °C), as confirmed in Section 1 and Table 3.4 of the official Infineon TC26x data sheet (V1.0, 2017-06). This frequency is sustained under worst-case voltage and thermal conditions with all safety monitors active.
Does SAK-TC265DC-40F200W BC support AUTOSAR Classic compliance out of the box?
Yes - the device includes hardware-enforced memory protection units (MPUs), standardized interrupt vectors, and ASCLIN/QSPI peripherals aligned with AUTOSAR BSW module requirements. Infineon provides certified AUTOSAR Basic Software packages (e.g., EB tresos) validated for this part number and BC-step silicon revision.
What is the purpose of the "DC" suffix in the part number SAK-TC265DC-40F200W BC?
The "DC" denotes the specific die revision and qualification level: "D" indicates the second major silicon revision (post-B and C steps), and "C" specifies the automotive-grade qualification per AEC-Q100 Grade 1, including extended temperature operation and enhanced ESD robustness (HBM ≥2 kV) as documented in Infineon's quality declarations (Section 3.37).
Can the DSADC module perform simultaneous sampling on multiple channels?
Yes - the DSADC supports up to four independent sigma-delta modulators with synchronized sampling start capability. Each modulator feeds into a dedicated digital filter path, enabling true simultaneous acquisition of motor phase currents or battery cell voltages without inter-channel skew.
