Product details
Overview
SAK-TC234L-24F200N 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), FlexRay v2.1, and GTM for autonomous I/O timing - deployed in automotive ADAS domain controllers.
For engineers reviewing the SAK-TC234L-24F200N AC datasheet, SAK-TC234L-24F200N AC pinout, SAK-TC234L-24F200N AC application, or SAK-TC234L-24F200N AC equivalent, key selection criteria include ASCLIN/LIN support up to 50 MBaud, ECC-protected memory architecture, safety-certified SMU/MTU/HSM options, and real-time deterministic peripheral handling via GTM and CCU6.
Technical Context
The SAK-TC234L-24F200N AC implements a dual-core lockstep safety architecture with primary TC1.6E scalar core and shadow core, enabling ISO 26262 ASIL-D compliance. Its System PLL delivers stable 200 MHz system clock from external crystal or oscillator input, while ERAY_PLL independently clocks the FlexRay module at 80 MHz.
On-chip bus hierarchy includes a 64-bit SRI crossbar for concurrent CPU, DMA, and memory access, plus SPB for peripheral control. All embedded memories (PFLASH, DFLASH, DSPR, PSPR) feature full ECC protection, and the MTU supports on-the-fly memory initialization and MBIST.

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-TC233L-24F180N AC | Single-core TC1.6E at 180 MHz; 1.5 MB PFLASH; no Ethernet MAC; 4 CAN nodes total | Targeted at cost-sensitive ASIL-B systems without Ethernet or high-bandwidth interconnect needs | Select when Ethernet, FlexRay, or >4 CAN nodes are not required and BOM cost reduction is prioritized |
| SAK-TC237L-32F200N AC | Triple-core lockstep (2x main + 1x shadow); 32-bit address space extension; 2.5 MB PFLASH; added SENT interface | Designed for higher-integration chassis domain controllers requiring more parallel safety partitions and sensor interfaces | Select when additional CPU throughput, SENT sensor support, or extended memory addressing is needed for complex motion control stacks |
Compared with SAK-TC234L-24F200N AC, the TC233 variant trades Ethernet and FlexRay for lower cost and power, while the TC237 adds core count and SENT but increases package size and thermal footprint - making the TC234 the optimal balance of ASIL-D capability, communication breadth, and TQFP-144 manufacturability.

FAQ
What is the maximum ambient temperature rating for SAK-TC234L-24F200N AC?
The device is qualified for operation from −40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This rating applies to all specified electrical parameters including 200 MHz CPU operation, VADC performance, and Ethernet MAC timing - verified across full voltage and process corners.
Does SAK-TC234L-24F200N AC include hardware cryptographic acceleration?
The base SAK-TC234L-24F200N AC does not integrate a Hardware Security Module (HSM); however, the pin-compatible SAK-TC234L-24F200N AC-H variant includes an optional HSM supporting AES-128/256, SHA-256, and RSA-2048. No cryptographic acceleration is present in the standard part.
Can the VADC measure signals beyond 5.5 V when supplied with 5.0 V reference?
No. The VADC input voltage range is strictly limited to 0 V to VDDA (5.0 V), and absolute maximum input is VDDA + 0.3 V (5.3 V). Applying >5.5 V risks permanent damage to input protection diodes and violates the Absolute Maximum Ratings table in the datasheet.
Is the Ethernet MAC compliant with IEEE 802.3-2015 standards?
Yes. The integrated Ethernet MAC supports IEEE 802.3-2015 features including full-duplex MII/RMII operation, auto-negotiation, pause frames, VLAN tagging (IEEE 802.1Q), and CRC-32 error detection - validated per clause 22 (MII) and clause 30 (RMII) specifications with guaranteed timing margins.
