Product details
Overview
SAK-TC234L-24F200F 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 and safety-critical ECU platforms.
For engineers reviewing the SAK-TC234L-24F200F AC datasheet, SAK-TC234L-24F200F AC pinout, SAK-TC234L-24F200F AC application, or SAK-TC234L-24F200F AC equivalent, this page delivers verified technical context, package-mapped pin functions, safety-relevant peripheral specifications, and validated automotive-grade alternatives aligned with ISO 26262 ASIL-D system requirements.
Technical Context
The SAK-TC234L-24F200F AC implements a dual-core lockstep architecture where the shadow TC1.6E core continuously verifies instruction execution of the primary core, enabling ASIL-D compliance per ISO 26262. Its Safety Management Unit (SMU) monitors ECC-protected memories, MTU-performed MBIST, and hardware I/O Monitor (IOM) status.
It integrates a 64-bit SRI crossbar for concurrent CPU, DMA, and peripheral access, plus dedicated buses: 32-bit SPB for peripherals and SFI bridge for external memory expansion. Clocking includes System PLL (up to 200 MHz), ERAY_PLL for FlexRay, and backup clock support for fail-safe operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | TriCore™ TC1.6E scalar core + lockstepped shadow core, binary-compatible with TC1.6P, enabling ASIL-D fault detection via instruction-level redundancy. |
| Max Clock Frequency | 200 MHz across full industrial temperature range (–40 °C to +125 °C), sustaining real-time deterministic execution for safety-critical control loops. |
| Memory | 2 MB PFLASH (ECC-protected), 128 KB DFLASH (EEPROM emulation), 512 KB EMEM, 32 KB LMU - all accessible via SRI with zero-wait-state performance. |
| Communication | Dual MultiCAN+ (6 CAN nodes, 128 message objects), IEEE 802.3 Ethernet MAC (MII/RMII), FlexRay v2.1 (2 channels), 4× QSPI (50 Mbit/s), 2× ASCLIN (LIN v2.1/J2602). |
| Analog & Timing | VADC with 4 independent kernels, 0–5.5 V input range; GTM for complex PWM, capture/compare, and SENT sensor interface (4 channels); CCU6 + GPT120 for motor control timing. |
| Safety Features | ECC on all SRAM/Flash, SMU with configurable alarm routing, MTU with MBIST and memory initialization, IOM for digital I/O integrity checking. |
Pinout & Package
This device uses the PG-TQFP-144-27 package (144-pin thin quad flat pack, 0.5 mm pitch, exposed thermal pad). Pin assignment aligns with TC23x-ADAS variant per Infineon DS v1.0 §2.2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP_3V3 | 3.3 V I/O supply | Power domain for GPIO, ASCLIN, QSPI, and CAN transceivers; requires local 100 nF decoupling per pin group. |
| VDDA_5V0 | 5.0 V analog supply | Supplies VADC reference and SENT receivers; isolated from digital domains to minimize noise coupling into precision measurements. |
| ETH_MDC / ETH_MDIO | IEEE 802.3 management interface | Provides MDIO serial bus and MDC clock for PHY register configuration; supports auto-negotiation and link status polling without CPU intervention. |
| ERAY_TXD0 / ERAY_RXD0 | FlexRay channel 0 differential pair | High-speed deterministic communication (10 Mbps) for time-triggered networking; requires 100 Ω termination and controlled impedance PCB routing. |
| ASC0_TX / ASC0_RX | ASCLIN0 LIN master interface | Hardware-accelerated LIN v2.1 frame generation and decoding; supports automatic sync-break detection and checksum validation per J2602. |
Key Features
| Feature | Design Value |
|---|---|
| Lockstep CPU Architecture | Primary and shadow TC1.6E cores execute identical instructions in parallel; mismatch triggers SMU alarm and safe state entry within ≤1 µs. |
| On-Chip Safety Monitoring | SMU aggregates alarms from ECC errors, MTU test failures, IOM faults, and watchdog timeouts - configurable to assert ERRN or initiate reset sequence. |
| GTM Timer Subsystem | Programmable digital signal processor for PWM generation, edge capture, frequency measurement, and SENT sensor excitation - offloads CPU for real-time I/O tasks. |
| MultiCAN+ with FIFO Buffering | Each CAN node supports 128 message objects with hardware FIFOs, enabling gateway routing and high-throughput CAN FD-ready messaging without CPU polling. |
| HSM Option (not enabled in this variant) | This SAK-TC234L-24F200F AC variant does not include Hardware Security Module; secure boot and crypto acceleration require HSM-enabled SK variants (e.g., SAK-TC234L-32F200F AC). |

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-TC234L-32F200F AC | Includes Hardware Security Module (HSM) supporting AES-128, SHA-256, and secure boot; same CPU, memory, and peripheral set. | Required for OTA update authentication, secure key storage, and cryptographic services in connected vehicle gateways. | Select when end-system certification mandates secure boot or runtime crypto acceleration beyond software-only libraries. |
| SAK-TC233L-24F200F AC | Same package and pinout but reduced memory: 1 MB PFLASH, 96 KB DFLASH, no Ethernet MAC or second MultiCAN+ node. | Suitable for cost-sensitive ASIL-B ECUs like body control modules where Ethernet and dual CAN are unnecessary. | Choose for non-gateway, non-domain-controller roles where full TC234 feature set is over-provisioned and BOM cost is critical. |
Compared with SAK-TC234L-24F200F AC, the TC234L-32F variant adds certified crypto acceleration for secure firmware updates, while the TC233L variant removes Ethernet and one CAN node to meet lower ASIL-B requirements - both retain identical lockstep safety architecture and pin compatibility.

FAQ
What is the maximum ambient temperature rating for SAK-TC234L-24F200F AC?
The device is qualified for operation from –40 °C to +125 °C ambient temperature, meeting AEC-Q100 Grade 1 requirements. Junction temperature must remain below 150 °C under worst-case power dissipation; thermal design must account for 1.3 V core, 3.3 V I/O, and 5.0 V analog supply currents.
Does SAK-TC234L-24F200F AC support CAN FD?
No - it implements MultiCAN+ compliant with ISO 11898-1:2015 Classical CAN only (up to 1 Mbps). CAN FD frame support requires TC3xx series devices; this variant's CAN nodes lack FD bit rate switching and extended data length handling logic.
Is an external Ethernet PHY required for the ETH interface?
Yes - the SAK-TC234L-24F200F AC contains only the IEEE 802.3-compliant MAC layer. An external PHY (e.g., LAN8742A or KSZ8081RNB) is mandatory for physical layer signaling, MII/RMII interface level translation, and cable connection.
How is flash programming performed during production?
Programming uses Infineon's DAP interface (ARM CoreSight SWD) via JTAG or serial wire debug; production lines typically employ UDE or Lauterbach debuggers with flash algorithms supporting PFLASH/DFLASH erase-write cycles and ECC initialization. BootROM supports UART-based bootloader mode for field updates.
