Product details
Overview
TLE9254SKXUMA1 from Infineon is a dual-channel high-speed CAN FD transceiver compliant with ISO 11898-2:2016, supporting data rates up to 5 Mbit/s with bus wake-up capability. It features two independent HS CAN channels, <10 µA standby current per channel, and integrated overtemperature and short-circuit protection. Used in automotive gateway modules and body control units where low-power bus monitoring and robust EMC performance are required.
For engineers reviewing the TLE9254SKXUMA1 datasheet, TLE9254SKXUMA1 pinout, TLE9254SKXUMA1 application, or TLE9254SKXUMA1 equivalent, key selection criteria include dual-channel CAN FD timing symmetry, ±40 V bus fault tolerance, wake-up pattern detection on STB-controlled standby mode, and PG-DSO-14 package compatibility with AEC-Q100 Grade 1 qualification.
Technical Context
The TLE9254SKXUMA1 implements two fully independent HS CAN physical layer interfaces, each with matched transmitter delay symmetry (<5 ns) and receiver propagation delay matching (<10 ns) to enable reliable 5 Mbit/s CAN FD operation. Its dual-mode architecture supports simultaneous normal operation and bus-wakeable standby on either channel via dedicated STB1/STB2 inputs.
Each channel integrates fail-safe logic including TxD timeout (1.2 ms typ.), undervoltage lockout on VCC (4.5 V min), and thermal shutdown at 165 °C. The device operates across an extended supply range of 4.5–6.0 V and maintains <1 µA bus leakage in power-down state while retaining wake-up sensitivity on CANH/CANL.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN FD Data Rate | Up to 5 Mbit/s - enables high-bandwidth firmware updates and sensor fusion in modern ECUs. |
| Standby Current (per channel) | <10 µA typ. - allows always-on bus monitoring without draining vehicle battery during sleep mode. |
| Bus Fault Tolerance | ±40 V on CANH/CANL - protects against load dump and jump-start transients per ISO 7637-2. |
| ESD Robustness | ±10 kV HBM on CAN pins - eliminates need for external TVS diodes in most automotive layouts. |
| Common-Mode Range | −12 V to +12 V - ensures reliable communication under severe ground offset conditions in chassis networks. |
| Transmitter Symmetry Error | <5 ns - minimizes bit-edge jitter critical for CAN FD arbitration and data phase integrity. |
| Wake-Up Pattern Detection | Supports ISO 11898-2 wake-up frames - enables selective channel activation without full system wake. |
Pinout & Package
Package: PG-DSO-14 (lead-based, RoHS-compliant, halogen-free); thermal pad connected to GND for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | TxD1 / TxD2 | CMOS input driving dominant/recessive states; internal pull-up to VCC enables open-drain microcontroller interface. |
| 2, 6 | GND1 / GND2 | Separate ground returns for each channel; must be tied to common PCB ground to prevent ground loop noise. |
| 3, 7 | VCC1 / VCC2 | Independent 4.5–6.0 V supplies per channel; requires local 100 nF decoupling to minimize switching noise coupling. |
| 4, 8 | RxD1 / RxD2 | CMOS output indicating bus state; active-low dominant signal compatible with standard CAN controllers. |
| 9, 12 | CANL2 / CANL1 | Differential low-side bus I/O; designed for direct connection to twisted-pair CAN bus with no external biasing. |
| 10, 13 | CANH2 / CANH1 | Differential high-side bus I/O; outputs 3.5 V recessive, 2.0 V dominant levels meeting ISO 11898-2 voltage thresholds. |
| 11, 14 | STB2 / STB1 | Active-high standby control; pulls high internally to enable automatic wake-on-bus activity when deasserted. |
| PAD | Thermal Pad | Exposed copper pad for solder attachment to PCB ground plane; mandatory for thermal compliance at 150 °C junction temp. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent CAN FD channels | Enables gateway routing between two isolated CAN domains without external multiplexing or controller overhead. |
| Bus wake-up pattern detection | Recognizes standardized ISO 11898-2 wake frames on either channel while consuming <10 µA, reducing ECU sleep current. |
| No external common-mode choke required | Ultra-low EME due to matched CANH/CANL edge symmetry allows direct bus connection in space-constrained modules. |
| Integrated TxD timeout | Auto-disables driver after 1.2 ms of continuous dominant state, preventing bus lockup from MCU firmware faults. |
| AEC-Q100 qualified Grade 1 | Validated for −40 °C to +125 °C ambient operation - suitable for engine bay, transmission, and under-hood applications. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP TJA1044GT | Single-channel, 2 Mbit/s max, no bus wake-up pattern detection; 15 µA standby current. | Lacks dual-channel integration and 5 Mbit/s support - requires two devices for equivalent functionality. | Select when cost-sensitive designs accept higher component count and reduced data rate headroom. |
| ST TLE6250G | Legacy CAN 2.0 only (1 Mbit/s), no CAN FD support, 100 µA standby current. | Not suitable for CAN FD migration paths or new ADAS/EPS platforms requiring >1 Mbit/s bandwidth. | Consider only for brownfield CAN 2.0 upgrades where 5 Mbit/s and ultra-low standby are not required. |
Compared with TJA1044GT and TLE6250G, the TLE9254SKXUMA1 delivers unique dual-channel 5 Mbit/s CAN FD capability with sub-10 µA standby per channel and integrated wake-up pattern recognition-enabling next-generation automotive domain controllers with consolidated communication layers and extended sleep autonomy.

FAQ
What is the maximum CAN FD data rate supported by TLE9254SKXUMA1?
The TLE9254SKXUMA1 supports CAN FD data frames up to 5 Mbit/s, verified through transmitter symmetry error <5 ns and receiver delay matching <10 ns per channel. This enables high-throughput diagnostics and OTA updates in modern ECU architectures without requiring external signal conditioning.
Does TLE9254SKXUMA1 require external common-mode chokes for EMC compliance?
No. The TLE9254SKXUMA1 achieves Class 5 CISPR 25 radiated emission limits without external common-mode chokes due to its optimized CANH/CANL edge symmetry and ultra-low electromagnetic emission (EME) profile across 30–1000 MHz.
How does the bus wake-up pattern function operate on TLE9254SKXUMA1?
In standby mode, the TLE9254SKXUMA1 monitors CANH/CANL for ISO 11898-2-defined wake-up patterns (e.g., dominant pulse ≥150 µs). Detection triggers RxD output assertion and exits standby within 10 µs, enabling rapid system wake without CPU polling.
Is TLE9254SKXUMA1 pin-compatible with earlier Infineon CAN transceivers like TLE6250?
No. The TLE9254SKXUMA1 uses a 14-pin PG-DSO package with dual-channel I/O mapping (e.g., separate VCC1/VCC2, STB1/STB2), whereas TLE6250 uses an 8-pin SOIC package with single-channel topology and incompatible pin assignments.
