Product details
Overview
SAK-TC233LC-24F133F AC from Infineon Technologies is a 32-bit AURIX™ TriCore™ microcontroller with a lockstepped TC1.6E CPU core operating up to 200 MHz, 2 MB program flash (PFLASH), 128 KB data flash (DFLASH) for EEPROM emulation, and integrated Ethernet MAC (MII/RMII), dual MultiCAN+ (6 CAN nodes), FlexRay v2.1 (ERAY), and GTM timer subsystem. It targets automotive ADAS domain controllers requiring ASIL-D compliance.
For engineers reviewing the SAK-TC233LC-24F133F AC datasheet, SAK-TC233LC-24F133F AC pinout, SAK-TC233LC-24F133F AC application, or SAK-TC233LC-24F133F AC equivalent, key selection criteria include functional safety architecture (lockstep + SMU + MTU), real-time I/O handling via GTM and SENT, deterministic communication stack support (CAN FD, FlexRay, Ethernet), and ECC-protected memory hierarchy.
Technical Context
The device implements a safety-critical dual-core lockstep architecture where the shadow core continuously verifies instruction execution of the primary TC1.6E core, enabling ASIL-D compliance per ISO 26262. Its Safety Management Unit (SMU) monitors clock, reset, voltage, and memory errors with configurable alarm routing.
Real-time peripheral control is handled by the Generic Timer Module (GTM), which provides autonomous PWM generation, capture/compare, and signal conditioning without CPU intervention. The VADC features four independent kernels with 0–5.5 V input range and hardware oversampling for sensor interface fidelity in harsh automotive environments.

Pinout & Package
SAK-TC233LC-24F133F AC is housed in a PG-TQFP-100-23 package (100-pin thin quad flat pack, 0.5 mm pitch, 14 × 14 mm body). Pin functions are defined per Section 2.3 of the TC233/TC234/TC237 datasheet (V1.0, 2017-03), with dedicated power domains (VDDP, VDDA, VDDC), JTAG/DAP debug, and function-multiplexed I/O grouped by peripheral cluster (e.g., ETH_MDC/MDIO, ERAY_TX/RX, CAN_TX/RX).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P00.0 – P00.15 | Port 0 general-purpose I/O | Configurable as GPIO, CAN0_TX/RX, ASCLIN0, QSPI0 signals; supports pull-up/pull-down and Schmitt-trigger input |
| P10.0 – P10.7 | Port 10 dedicated ETH interface | Fixed MII/RMII pins (ETH_RXD0–3, ETH_TXD0–3, ETH_TX_EN, ETH_CRS_DV, ETH_REF_CLK); no alternate functions |
| P15.0 – P15.1 | FlexRay channel A differential pair | ERAY_A_TX and ERAY_A_RX - LVDS-compliant, 100 Ω termination required; supports wake-up and cold-start protocols |
| TCK, TMS, TDI, TDO, TRSTN | JTAG boundary-scan interface | IEEE 1149.1 compliant; enables structural test, flash programming, and real-time debugging at OCDS Level 1 |
| VDDP0, VDDP1, VDDA, VDDC | Power supply domains | VDDP0/VDDP1 = 3.3 V I/O; VDDA = 5 V analog; VDDC = 1.3 V core - each with dedicated decoupling and monitoring |
Key Features
| Feature | Design Value |
|---|---|
| Lockstep CPU Architecture | Primary TC1.6E core and shadow core execute identical instructions with cycle-accurate comparison - detects transient faults for ASIL-D systems |
| GTM Real-Time Subsystem | Autonomous signal processing engine with 12 timers, 16 pattern generators, and 32 input capture units - offloads CPU for motor control and sensor fusion |
| ECC-Protected Memory Hierarchy | All SRAM, Flash, and ROM blocks feature single-bit error correction and double-bit error detection - prevents silent data corruption in safety-critical code/data |
| MultiCAN+ with FIFO Buffering | Two modules, each with 3 CAN nodes and 128 message objects; hardware FIFOs reduce CPU load during high-bandwidth gateway operations |
| Hardware Security Module (HSM) | Optional embedded secure co-processor supporting AES-128/256, SHA-256, RSA-2048, and secure boot - isolates cryptographic keys from main CPU memory space |

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 | Higher clock (200 MHz vs. 133 MHz), larger PFLASH (4 MB), adds HSM as standard, same PG-TQFP-144 package | Supports more complex ASIL-D stacks (e.g., zonal E/E architecture) with larger code footprint and cryptographic acceleration | Select when requiring >2 MB flash, built-in HSM, or higher computational throughput for multi-domain consolidation |
| SAK-TC222L-16F80F AC | Single-core TC1.6E (no lockstep), 80 MHz max, 1 MB PFLASH, PG-VQFN-48 package, no Ethernet/FlexRay | Targeted at ASIL-B applications like HVAC or lighting control - lacks safety mechanisms for chassis-critical functions | Select only for cost-sensitive, non-chassis applications where ASIL-D is not mandated and peripheral count is lower |
Compared with SAK-TC233LC-24F133F AC, the TC234LP offers higher performance and security integration for next-gen gateways, while the TC222L serves simpler ASIL-B domains - neither matches its balance of ASIL-D capability, Ethernet/FlexRay connectivity, and TQFP-100 compactness for mid-tier ADAS controllers.

FAQ
What safety certifications does the SAK-TC233LC-24F133F AC support?
The device supports ISO 26262 ASIL-D compliance through hardware-level safety mechanisms including lockstep CPU cores, Safety Management Unit (SMU) with 30+ monitored sources, ECC-protected memories, Memory Test Unit (MTU), and Hardware I/O Monitor (IOM). Infineon provides certified safety manuals, FMEDA reports, and diagnostic software libraries to accelerate functional safety certification.
Does this MCU include an integrated Ethernet PHY?
No, the SAK-TC233LC-24F133F AC integrates only the IEEE 802.3-compliant Ethernet MAC layer with MII and RMII interfaces. An external PHY (e.g., Infineon's TLF35584 or third-party 10/100BASE-TX PHY) must be used for physical layer signaling, with proper impedance-controlled PCB routing and magnetics.
Can the VADC measure signals above 3.3 V directly?
Yes - the VADC supports an input voltage range of 0 V to 5.5 V (referenced to VDDA = 5 V), enabling direct measurement of automotive sensor outputs (e.g., throttle position, brake pressure) without external level-shifting circuitry, provided VDDA is properly supplied and decoupled.
Is the Hardware Security Module (HSM) enabled by default on this variant?
No - the SAK-TC233LC-24F133F AC does not integrate the HSM as standard; it is available only on select TC23x variants (e.g., TC234LP). This part relies on software-based cryptographic libraries running on the main TriCore core, with secure boot supported via BootROM and flash protection mechanisms.
