Product details
Overview
SAK-TC233LP-32F200F 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 - designed for automotive ADAS and safety-critical ECU applications.
For engineers reviewing the SAK-TC233LP-32F200F AC datasheet, SAK-TC233LP-32F200F AC pinout, SAK-TC233LP-32F200F AC application, or SAK-TC233LP-32F200F AC equivalent, key selection criteria include ASIL-D compliance support via SMU/MTU/ECC memory, real-time deterministic I/O via GTM and CCU6, LIN/SENT sensor interface capability, and hardware security module (HSM) readiness in compatible variants.
Technical Context
The SAK-TC233LP-32F200F AC implements a dual-core lockstep architecture with primary TC1.6E scalar core and shadow core for fault detection, coupled with ECC-protected memories (PFLASH, DFLASH, SRAM), Safety Management Unit (SMU), and Memory Test Unit (MTU) enabling ISO 26262 ASIL-D system-level certification. Its clock system integrates System PLL and ERAY_PLL for independent domain timing.
Peripheral integration includes IEEE 802.3-compliant Ethernet MAC with MII/RMII PHY interfaces, two MultiCAN+ modules supporting 6 CAN FD-capable nodes with 128 message objects, four QSPI channels (50 Mbit/s), and GTM providing autonomous PWM generation, time-triggered I/O, and high-resolution capture - all accessible via 64-bit SRI crossbar for low-latency bus arbitration.

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 | Includes hardware security module (HSM); adds 1 MB additional PFLASH and 32 KB additional DFLASH | Required where secure boot, cryptographic acceleration, or OTA update signing is mandated | Select when HSM functionality is needed - otherwise identical pinout, software compatibility, and safety features |
| SPC574SADPT1 | Power Architecture-based, 200 MHz, 2 MB Flash, ASIL-D certified but lacks Ethernet MAC and FlexRay | Suitable for powertrain ECUs without Ethernet/FlexRay requirements; different toolchain (S32DS vs. DAVE™/HighTec) | Choose for legacy Power Architecture ecosystems or where Ethernet/FlexRay are unnecessary - not pin-compatible |
Compared with SAK-TC234LP-32F200F AC, this part omits HSM and reduces flash capacity, lowering cost for non-security-critical ADAS sensors; versus SPC574SADPT1, it offers native Ethernet and FlexRay but requires TriCore toolchain migration and higher BOM complexity for external PHY.

FAQ
What is the maximum ambient temperature rating for SAK-TC233LP-32F200F 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 the full 200 MHz CPU frequency range and all integrated peripherals including Ethernet MAC and FlexRay, with thermal derating not required within this envelope.
Does SAK-TC233LP-32F200F AC support CAN FD?
Yes - both 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 message filtering. The 128 message objects are allocated across six CAN nodes with configurable FIFO depth per node.
Is an external Ethernet PHY required for the built-in MAC?
Yes - the SAK-TC233LP-32F200F AC integrates only the IEEE 802.3-compliant Media Access Controller (MAC); an external PHY chip is required for physical layer signaling. It supports both MII (4-bit parallel) and RMII (2-pin) interfaces, with pin multiplexing allowing shared use of ETH_MDIO/MDC for MDIO management.
How is functional safety certification addressed in this microcontroller?
The device includes integrated safety mechanisms: lockstep CPU cores, ECC on all memories, Safety Management Unit (SMU), Memory Test Unit (MTU), and hardware I/O Monitor (IOM). These enable ASIL-D decomposition per ISO 26262 Part 10, with documentation and safety manuals provided by Infineon for FMEDA and diagnostic coverage analysis.
