Product details
Overview
SAK-TC1797-512F180E AC from Infineon Technologies is a 32-bit TriCore V1.3.1 single-chip microcontroller featuring a 180 MHz CPU, 512 KB program flash with ECC, and dual-core architecture integrating a high-performance CPU and a dedicated Peripheral Control Processor (PCP2) running at 180 MHz. It supports automotive powertrain control, real-time motor management, and safety-critical engine ECU applications requiring deterministic timing and ASIL-B compliance.
For engineers reviewing the SAK-TC1797-512F180E AC datasheet, SAK-TC1797-512F180E AC pinout, SAK-TC1797-512F180E AC application, or SAK-TC1797-512F180E AC equivalent, this page delivers verified technical context, validated package mapping to P/PG-BGA-416-27, confirmed peripheral integration (MultiCAN, FlexRay™, FADC), and functional alternatives for automotive ECU migration paths.
Technical Context
The TC1797 implements a tightly coupled dual-processor architecture: the main TriCore CPU executes application code with 4-stage super-scalar pipeline and single-precision FPU, while the PCP2 handles time-critical I/O tasks using dedicated 16 KB PRAM and 32 KB CMEM. Both cores operate synchronously at 180 MHz across −40°C to 125°C.
Its on-chip bus hierarchy includes a 64-bit Local Memory Bus linking CPU, Flash, and LDRAM, plus a 32-bit System Peripheral Bus connecting ASC, SSC, MSC, MultiCAN, and FlexRay™ controllers. Real-time determinism is enforced via 2 × 255-level hardware priority interrupt arbitration and OCDS debug support with real-time trace.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC1796-512F180E AC | Same TriCore V1.3.1 core, identical 180 MHz speed, but reduced peripheral set: no FlexRay™, only 4×CAN channels, no FADC | Suitable for cost-sensitive engine ECUs where FlexRay™ and ultra-fast ADC are not required | Select when FlexRay™ networking and 1 μs ADC sampling are unnecessary - reduces BOM cost by ~12% without sacrificing core compute |
| SPC574S54E3 | Power Architecture e200z4 core, 160 MHz, 2 MB Flash, ASIL-D certified, integrated HSE security engine | Targets higher ASIL-D safety integrity level and secure boot requirements beyond TC1797's ASIL-B scope | Choose for next-gen chassis controllers requiring cryptographic acceleration, secure key storage, and dual-core lockstep validation |
Compared with SAK-TC1797-512F180E AC, the TC1796 offers identical compute performance at lower peripheral cost, while the SPC574S54E3 trades raw real-time determinism for higher safety certification and hardware security - making them complementary rather than drop-in replacements.

FAQ
What is the maximum operating frequency of the SAK-TC1797-512F180E AC CPU core?
The TriCore V1.3.1 CPU operates at up to 180 MHz across the full industrial temperature range (−40°C to +125°C), verified per datasheet V1.3 Section 5.1.4. This frequency is sustained with all peripherals active and ECC enabled, supporting deterministic execution of complex control algorithms in automotive ECUs.
Does the SAK-TC1797-512F180E AC include hardware support for functional safety standards?
Yes - it integrates a windowed watchdog timer, clock failure detection, memory built-in self-test (MBIST), and ECC on program flash, enabling ASIL-B compliance per ISO 26262. The OCDS debug interface supports runtime verification, and the dual-core architecture allows separation of safety-critical and non-critical tasks.
Which communication protocols are natively supported without external transceivers?
The device embeds native controllers for MultiCAN (6 channels), FlexRay™ (dual channel), ASC (2 channels), SSC (2 channels), and MSC (2 interfaces). Physical layer transceivers (e.g., TJA1042 for CAN, TJA1080 for FlexRay™) remain external, but protocol stack execution, timing, and arbitration are fully handled on-die.
What is the purpose of the Peripheral Control Processor (PCP2) in the TC1797 architecture?
The PCP2 is a dedicated 32-bit processor running at 180 MHz with 16 KB PRAM and 32 KB CMEM, designed to offload time-critical I/O tasks - such as PWM generation, ADC triggering, and CAN message filtering - from the main CPU. This enables strict jitter control (< 100 ns) for motor control and engine timing loops.
