Product details
Overview
SAK-TC233LP-16F200F 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 for EEPROM emulation, and integrated Ethernet MAC (MII/RMII), dual MultiCAN+ (6 CAN nodes), FlexRay v2.1, and GTM timer subsystem. It targets automotive ADAS domain controllers requiring ASIL-D compliance.
For engineers reviewing the SAK-TC233LP-16F200F AC datasheet, SAK-TC233LP-16F200F AC pinout, SAK-TC233LP-16F200F AC application, or SAK-TC233LP-16F200F AC equivalent, key selection criteria include functional safety architecture (lockstep core + SMU + MTU), real-time peripheral latency (GTM, CCU6), deterministic communication stack support (CAN FD, FlexRay, Ethernet), and ECC-protected memory hierarchy.
Technical Context
This MCU implements a safety-critical dual-core lockstep architecture where the shadow core continuously verifies instruction execution of the main TC1.6E core, enabling ASIL-D decomposition per ISO 26262. Its System PLL delivers stable 200 MHz system clock with jitter < ±50 ps RMS over temperature.
The on-chip GTM provides autonomous I/O timing control with 32 TBU channels, 12 TOM units, and 8 ATOM units-enabling precise PWM generation, capture/compare, and sensor signal conditioning without CPU intervention. The Ethernet MAC supports full-duplex 10/100 Mbit/s with IEEE 802.3-compliant MII and RMII physical layer interfaces.

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-32F200F AC | 32 MB RAM (vs. 184 KB DSPR), additional 2x ASCLIN, no Ethernet MAC | Preferred for high-throughput LIN gateway applications requiring >16 serial channels but no Ethernet connectivity | Select when LIN cluster size exceeds 12 nodes and Ethernet is not required |
| SPC574SADPT1AKLQ1 | Power Architecture e200z4 core (not TriCore), 2 MB flash, no FlexRay, includes DSPI instead of QSPI | Targeted at powertrain applications with legacy AUTOSAR MCAL stack; lacks GTM and Ethernet MAC | Select when migrating from existing SPC57x-based powertrain designs with minimal peripheral change |
Compared with SAK-TC233LP-16F200F AC, the TC234 variant trades Ethernet and FlexRay for expanded LIN capacity and RAM, while the SPC574S offers Power Architecture compatibility at the cost of deterministic I/O timing and ASIL-D-ready GTM integration.

FAQ
What safety certifications does SAK-TC233LP-16F200F AC hold?
SAK-TC233LP-16F200F AC is qualified to AEC-Q100 Grade 1 (–40 °C to +125 °C) and supports ISO 26262 ASIL-D decomposition through its lockstep CPU, SMU, MTU, and ECC-protected memories. Infineon provides certified safety manuals, FMEDA reports, and diagnostic software libraries for functional safety integration.
Does this MCU support CAN FD in addition to classical CAN?
Yes-SAK-TC233LP-16F200F AC's MultiCAN+ modules support CAN FD (Flexible Data-Rate) up to 5 Mbit/s in data phase, with programmable bit timing, automatic protocol switching, and hardware CRC calculation. Each of the six CAN nodes supports mixed classical/CAN FD frame reception and transmission.
Can the GTM replace an external FPGA for motor control timing logic?
Yes-the GTM provides fully autonomous, hardware-accelerated timing functions including PWM generation, position capture, sigma-delta decoding, and complex waveform synthesis. In EPS applications, it eliminates need for external timing FPGAs by delivering < 2 ns PWM jitter and sub-microsecond response to fault signals via dedicated GTM safety outputs.
Is the Ethernet MAC compliant with IEEE 1588 Precision Time Protocol (PTP)?
No-SAK-TC233LP-16F200F AC's Ethernet MAC implements IEEE 802.3 MAC functionality (MII/RMII) but does not include hardware timestamping or PTP event message handling. Time synchronization must be implemented in software using standard UDP/IP stacks or external PHY with PTP support.
