Product details
Overview
SAK-TC237LP-32F200N AC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a lockstepped TC1.6E CPU core operating at up to 200 MHz, 2 MB program flash, 128 KB data flash (EEPROM-emulated), and integrated Ethernet MAC (MII/RMII), dual MultiCAN+ (6 CAN nodes), and FlexRay v2.1 - designed for automotive ASIL-D safety-critical ADAS and chassis control applications.
For engineers reviewing the SAK-TC237LP-32F200N AC datasheet, SAK-TC237LP-32F200N AC pinout, SAK-TC237LP-32F200N AC application, or SAK-TC237LP-32F200N AC equivalent, key selection criteria include ASIL-D compliance support, dual-core lockstep timing integrity, on-chip HSM availability, ECC-protected memory hierarchy, and deterministic real-time peripheral latency for brake-by-wire and steer-by-wire systems.
Technical Context
The TC237LP implements a safety-certified dual-core lockstep architecture where the shadow core continuously verifies instruction execution against the primary TC1.6E core, enabling hardware-level fault detection per ISO 26262 ASIL-D requirements. It integrates a Safety Management Unit (SMU) and Memory Test Unit (MTU) with built-in ECC and MBIST for runtime memory integrity checks.
Its peripheral set includes two independent MultiCAN+ modules (3 CAN nodes each, 128 message objects), one IEEE 802.3-compliant Ethernet MAC with MII/RMII PHY interface, and an E-Ray module supporting FlexRay v2.1 communication - all accessible via a 64-bit crossbar interconnect (SRI) ensuring deterministic bus arbitration and low-latency I/O response.

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-TC234LP-32F200N AC | Same core, 1.5 MB PFLASH, no Ethernet MAC, only 1 MultiCAN+ (3 nodes), no E-Ray - lacks FlexRay and Ethernet interfaces. | Suitable for mid-tier ADAS ECUs without backbone Ethernet or FlexRay requirements (e.g., parking assist). | Select when Ethernet/FlexRay are unnecessary and cost optimization is prioritized over communication flexibility. |
| SAK-TC277TP-64F200N AC | Triple-core (2x TC1.6E + 1x TC1.6E lockstep), 4 MB PFLASH, dual Ethernet MAC, 3x MultiCAN+, dual E-Ray - higher integration and performance tier. | Targeted at zonal controllers and high-end autonomous driving platforms requiring concurrent real-time domains. | Choose when multi-domain isolation, higher bandwidth, or future-proofing for L3+ autonomy is required. |
Compared with SAK-TC237LP-32F200N AC, the TC234 offers reduced peripheral count and memory for cost-sensitive applications, while the TC277 delivers triple-core scalability and dual Ethernet for next-generation zonal architectures - making the TC237 the optimal balance of ASIL-D capability, FlexRay/Ethernet connectivity, and footprint efficiency.

FAQ
What safety certifications does the SAK-TC237LP-32F200N AC hold?
The SAK-TC237LP-32F200N AC is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), supports ISO 26262 ASIL-D development per certified safety manual (Infineon TC23x Safety Manual V1.2), and includes hardware safety mechanisms such as lockstep core checking, SMU alarm generation, and ECC-protected memories validated for automotive safety lifecycles.
Does this MCU include an integrated Ethernet PHY?
No - the SAK-TC237LP-32F200N AC integrates only the IEEE 802.3-compliant Ethernet MAC layer with MII and RMII interfaces. An external PHY (e.g., LAN8742A or KSZ8081RNA) must be used for physical layer signaling, with precise timing alignment specified in the datasheet Section 3.21.
Can the HSM (Hardware Security Module) be enabled on this variant?
Yes - the SAK-TC237LP-32F200N AC includes an optional HSM block supporting AES-128/256, SHA-256, RSA-2048, and secure boot key management. Its availability depends on factory configuration; the "LP" suffix indicates HSM-capable silicon, and firmware activation requires Infineon's HSM API and certificate provisioning workflow.
What is the maximum supported QSPI clock frequency in master mode?
The QSPI peripheral supports up to 50 Mbit/s in master mode, as confirmed in Section 3.20 of the TC233/TC234/TC237 datasheet V1.0 (2017-03). This enables fast code execution from external flash (XIP) or high-bandwidth sensor data streaming (e.g., radar ADC buffers) with programmable clock dividers and delay tuning.
