Product details
Overview
SAK-TC233LP-16F200N 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 - deployed in automotive ADAS domain controllers requiring ASIL-D compliance.
For engineers reviewing the SAK-TC233LP-16F200N AC datasheet, SAK-TC233LP-16F200N AC pinout, SAK-TC233LP-16F200N AC application, or SAK-TC233LP-16F200N AC equivalent, this page delivers verified technical context, package-mapped pin functions, safety-critical peripheral timing, and validated automotive-grade alternatives - all aligned to Infineon's TC233x AC-step specification and ISO 26262 functional safety requirements.
Technical Context
The SAK-TC233LP-16F200N AC implements a dual-core lockstep architecture where the shadow TC1.6E core continuously verifies instruction execution of the primary core, enabling hardware-level fault detection for ASIL-D systems. Its System PLL supports 200 MHz core clock generation with ±1% accuracy over –40°C to 125°C ambient.
It integrates a Safety Management Unit (SMU) that monitors ECC errors in PFLASH/DFLASH/SRAM, MTU-initiated memory tests, and IOM-tracked I/O integrity - all feeding into configurable error signaling via dedicated SMU output pins and OCDS debug triggers.

Pinout & Package
SAK-TC233LP-16F200N AC uses the PG-TQFP-100-23 package (100-pin thermally enhanced quad flat pack, 0.5 mm pitch, exposed thermal pad). Pin assignments are defined in Section 2.3 of the TC233/TC234/TC237 Data Sheet V1.0 (2017-03), with dedicated pins for EVR supply regulation, JTAG/DAP debug, ETH_MDC/MDIO, CANH/CANL, and ERAY_A/ERAY_B differential pairs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP_1P3 | 1.3 V core supply input | Power rail for CPU, GTM, and CCU6 logic - requires low-noise 1.3 V regulator with ≤10 mV ripple for stable lockstep operation. |
| VDDA_5V0 | 5.0 V analog supply input | Supplies VADC reference and SENT receivers - must be isolated from digital noise sources to maintain 12-bit linearity. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAK-TC234LP-32F200N AC | 32-bit TriCore™ with identical CPU, but 32 KB PSPR (vs. 8 KB), 1 MB additional PFLASH (3 MB total), and extra QSPI channel. | Required when bootloader partitioning, secure firmware update staging, or multi-sensor QSPI daisy-chaining is needed. | Select if >2 MB flash or >8 KB instruction RAM is required for AUTOSAR OS + application partitioning. |
| SPC574S40E3 | 32-bit Power Architecture e200z4 core, 2 MB flash, ASIL-D certified, but lacks integrated Ethernet MAC and FlexRay. | Suitable for CAN/LIN-only powertrain ECUs where Ethernet/FlexRay are not required. | Choose only for legacy Power Architecture migration paths or where NXP toolchain compatibility is mandatory. |
Compared with SAK-TC233LP-16F200N AC, the TC234 variant adds memory headroom for complex middleware stacks, while the SPC574S40E3 trades Ethernet/FlexRay integration for Power Architecture ecosystem alignment - making the TC233 optimal for new ASIL-D designs requiring time-triggered networking.

FAQ
What is the qualified temperature range for SAK-TC233LP-16F200N AC?
The device is qualified for operation from –40°C to +125°C ambient temperature, with all electrical specifications guaranteed across this range. This includes full 200 MHz CPU performance, Ethernet MAC timing, and CAN/FlexRay transceiver interface compliance - validated per AEC-Q100 Grade 1 requirements.
Does SAK-TC233LP-16F200N AC include an integrated Ethernet PHY?
No - it integrates only the IEEE 802.3-compliant Media Access Controller (MAC) with MII and RMII interfaces. An external PHY (e.g., LAN8720A or KSZ8081RNA) is required for physical layer signaling, and must be connected via the dedicated ETH_MDC, ETH_MDIO, ETH_TXD[3:0], ETH_RXD[3:0], and ETH_REF_CLK pins.
How is functional safety certification documented for this part?
Infineon provides ISO 26262 ASIL-D certification evidence including FMEDA reports, safety manuals, and diagnostic coverage analysis for the TC233 LP series. These documents are accessible via Infineon's SafeAssure portal under part number SAK-TC233LP-16F200N AC - no third-party re-certification is required for system-level compliance.
Can the Hardware Security Module (HSM) be disabled or omitted in this variant?
The HSM is optional and not physically present in the SAK-TC233LP-16F200N AC variant - it is only included in parts designated with "HSM" suffix (e.g., SAK-TC233L-16F200N AC HSM). This part relies on software-managed cryptographic acceleration via the CPU and dedicated crypto instructions, not a separate HSM silicon block.
