Product details
Overview
IFX1051SJXUMA1 from Infineon Technologies is an industrial-grade High-Speed CAN-FD transceiver compliant with ISO 11898-2, acting as the physical-layer interface between a CAN controller and differential HS CAN bus. It supports data rates up to 2 MBit/s, features VIO voltage adaptation for 3.3 V microcontrollers, and delivers guaranteed loop delay symmetry ≤255 ns for reliable CAN FD frame transmission in factory automation and motion-control systems.
For engineers reviewing the IFX1051SJXUMA1 datasheet, IFX1051SJXUMA1 pinout, IFX1051SJXUMA1 application, or IFX1051SJXUMA1 equivalent, key selection criteria include ESD robustness (10 kV HBM), CAN short-circuit protection (to ground, battery, VCC), TxD time-out ≥4.5 ms, and dual-package availability (PG-DSO-8 and PG-TSON-8) for layout flexibility in industrial embedded designs.
Technical Context
The IFX1051SJXUMA1 implements a fully differential transmitter and receiver pair with matched propagation delays (tLoop(H,L) and tLoop(L,H) ≤255 ns), enabling precise timing alignment required for CAN FD's higher-bitrate arbitration and data phases. Its internal biasing network maintains recessive bus state without external resistors, and the RM pin enables hardware-selectable Receive-only mode for fault containment.
It operates across extended supply ranges: VCC = 4.5–27 V for bus-side power and VIO = 2.7–5.5 V for logic-level interfacing. The transceiver integrates overtemperature protection, short-circuit proof outputs, and failsafe TxD time-out-ensuring bus integrity during controller lockup in harsh industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 2 MBit/s - Enables full CAN FD payload and bitrate flexibility in high-bandwidth industrial networks. |
| Loop Delay Symmetry | ≤255 ns - Guarantees deterministic signal propagation for bit-level arbitration compliance in CAN FD. |
| ESD Robustness (HBM) | 10 kV - Protects against electrostatic discharge during handling and operation in unshielded factory settings. |
| VIO Supply Range | 2.7–5.5 V - Allows direct interfacing with 3.3 V or 5 V microcontrollers without level-shifting circuitry. |
| TxD Time-out Duration | ≥4.5 ms - Prevents bus blocking in long-distance networks (>1 km) while tolerating extended dominant states. |
| Common Mode Range | −30 V to +30 V - Ensures immunity to ground potential differences across distributed industrial nodes. |
| Bus Leakage (Power-down) | <1 µA - Maintains passive, non-intrusive behavior on CANH/CANL when disabled, preserving network integrity. |
Pinout & Package
IFX1051SJXUMA1 is packaged in RoHS-compliant, halogen-free PG-DSO-8 (SOIC-8) with exposed pad thermal enhancement. The package supports automated optical inspection (AOI) and meets JEDEC JESD47 qualification standards for industrial reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD | Transmit Data Input | CMOS-compatible input with internal pull-up to VIO; "low" asserts dominant bus state. |
| 2 GND | Ground Reference | Common return path for VCC, VIO, and bus biasing; must be low-impedance for EMI suppression. |
| 3 VCC | Transmitter Supply | 4.5–27 V bus-side supply; requires 100 nF decoupling capacitor to GND for transient stability. |
| 4 RxD | Receive Data Output | CMOS output referenced to VIO; "low" indicates dominant bus state, "high" recessive. |
| 5 VIO | Digital Supply Input | 2.7–5.5 V logic supply; sets input thresholds and output levels for TxD/RxD/RM pins. |
| 6 CANL | CAN Bus Low I/O | Differential bus terminal; sinks current during dominant state; biased to ~2.2 V in recessive state. |
| 7 CANH | CAN Bus High I/O | Differential bus terminal; sources current during dominant state; biased to ~3.0 V in recessive state. |
| 8 RM | Receive-only Mode Input | Internal pull-down to GND; driven "high" to disable transmitter and enter fail-safe listen-only mode. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898-2 Compliance | Fully compliant with industrial HS CAN physical layer standard, including common-mode range, slew rate, and fault tolerance. |
| Receive-only Mode (RM) | Hardware-enabled mode disables transmitter while retaining full bus monitoring-critical for diagnostic and safety-critical nodes. |
| VIO Voltage Adaptation | Eliminates need for external level shifters when interfacing with 3.3 V microcontrollers in mixed-voltage systems. |
| Enhanced EME/EMI Performance | Low electromagnetic emission and wide common-mode immunity reduce radiated noise and improve system-level EMC certification success. |
| Fail-Safe Short-Circuit Protection | Withstands CANH/CANL short to ground, battery, or VCC without latch-up or damage-enabling robust deployment in motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar HS CAN-FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN1042DRBR | Supports wake-up via bus activity; lower VCC min (4.5 V same); no VIO pin (fixed 3.3 V logic). | Designed for automotive body electronics with wake-on-CAN; lacks industrial VIO adaptability and extended VCC range. | Choose TCAN1042DRBR only if wake-up functionality is required and system uses fixed 3.3 V logic supply. |
| SN65HVD256DR | Classical CAN only (1 Mbps max); no CAN FD support; no TxD time-out; 5 V logic only. | Suitable for legacy industrial CAN networks where bandwidth and fail-safe timing are not critical. | Use SN65HVD256DR only for cost-sensitive, low-speed upgrades where CAN FD and 2 MBit/s are unnecessary. |
Compared with TCAN1042DRBR and SN65HVD256DR, the IFX1051SJXUMA1 uniquely combines CAN FD readiness, VIO voltage adaptability, and industrial-grade fault protection-making it optimal for new-design industrial networks demanding future-proof bandwidth and robustness.

FAQ
What is the maximum supported CAN FD data rate for IFX1051SJXUMA1?
The IFX1051SJXUMA1 supports CAN FD data frames up to 2 MBit/s, verified by guaranteed loop delay symmetry ≤255 ns and differential output slew rate optimization per ISO 11898-2. This enables full utilization of CAN FD's flexible data-rate capability in industrial networks without requiring external timing compensation.
Does IFX1051SJXUMA1 require external bus termination resistors?
No, the IFX1051SJXUMA1 does not require external termination resistors for basic operation. Its internal biasing network maintains the recessive bus state, though standard 120 Ω end-of-line termination remains necessary for impedance matching in linear bus topologies per ISO 11898-2 specifications.
How does the RM (Receive-only Mode) pin function in practice?
The RM pin is an active-high input with internal pull-down. When held high, it disables the transmitter while keeping the receiver fully operational-allowing the node to monitor bus traffic without transmitting. This is used for diagnostics, safety shutdowns, or hot-swap isolation in multi-node industrial systems.
Can IFX1051SJXUMA1 operate with a 24 V supply on VCC and 3.3 V on VIO simultaneously?
Yes. The IFX1051SJXUMA1 is explicitly designed for mixed-supply operation: VCC supports 4.5–27 V (including 24 V industrial rails), while VIO accepts 2.7–5.5 V (e.g., 3.3 V MCU logic). This eliminates level-shifters and simplifies integration into systems with separate power domains.
