Product details
Overview
TLE9254VSKXUMA1 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. It features bus wake-up pattern detection, VIO voltage adaptation (3.3 V/5 V), and stand-by mode with <10 µA quiescent current per channel. Used in automotive gateway modules and body control units for robust HS CAN communication under harsh EMI conditions.
For engineers reviewing the TLE9254VSKXUMA1 datasheet, TLE9254VSKXUMA1 pinout, TLE9254VSKXUMA1 application, or TLE9254VSKXUMA1 equivalent, key selection criteria include dual-channel CAN FD timing symmetry, ±40 V bus fault tolerance, ISO 7637 transient immunity, and stand-by wake-up behavior without external biasing.
Technical Context
The TLE9254VSKXUMA1 implements two independent HS CAN FD physical layer channels with matched transmitter delay symmetry (<5 ns) and receiver propagation delay matching (<10 ns), enabling reliable 5 Mbit/s data frame transmission. Each channel integrates dedicated STB control, internal pull-up on TxD/STB pins, and low-power wake-up logic that detects bus-level patterns while drawing <10 µA from VCC.
It supports dual-supply operation: VCC (4.5–6.0 V) powers transmitters and protection circuitry, while VIO (3.0–6.0 V) sets logic I/O levels for microcontroller interfacing. Fail-safe functions include TxD timeout, overtemperature shutdown (>150 °C), and short-circuit protection to battery, ground, and VCC on both CANH/CANL lines.
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. |
| Stand-by Quiescent Current | <10 µA per channel - allows always-on bus monitoring in vehicle sleep modes without battery drain. |
| Common-Mode Range | ±40 V - ensures robust operation during load-dump transients and ground offset in distributed automotive networks. |
| ESD Robustness (CANH/CANL) | ±10 kV HBM - eliminates need for external TVS diodes in most automotive PCB layouts. |
| VIO Supply Range | 3.0–6.0 V - supports direct interface to 3.3 V or 5 V microcontrollers without level shifters. |
| Bus Fault Protection | CANH/CANL short-circuit proof to battery, ground, and VCC - prevents latch-up and damage during wiring faults. |
| Wake-up Pattern Detection | Hardware-based bus wake-up logic - triggers RxD assertion without MCU intervention, reducing system latency. |
Pinout & Package
Package: PG-DSO-14 (lead-based, RoHS-compliant, halogen-free); thermal pad (PAD) must be connected to PCB ground plane for thermal management and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 TxD1 | Transmit input (Ch1) | CMOS input with internal VCC pull-up; dominant state = low; drives CANH1/CANL1 via differential transmitter. |
| 2 GND1 | Channel 1 ground reference | Mandatory connection to common PCB ground; must be tied to GND2 to avoid ground loop-induced EMI. |
| 3 VCC | Transmitter supply | 4.5–6.0 V supply; requires 100 nF decoupling capacitor to GND; can be disabled in stand-by mode. |
| 4 RxD1 | Receive output (Ch1) | CMOS output; dominant = low; asserts wake-up signal during bus activity in stand-by mode. |
| 5 GND2 | Channel 2 ground reference | Shared ground with GND1; ensures matched return paths for both CAN channels. |
| 6 TxD2 | Transmit input (Ch2) | Independent CMOS input with internal VCC pull-up; enables dual-bus topology (e.g., powertrain + body networks). |
| 7 RxD2 | Receive output (Ch2) | Active-low output synchronized to CANH2/CANL2; used for interrupt generation in multi-controller systems. |
| 8 STB2 | Stand-by control (Ch2) | High-active input; internal VCC pull-up; disables transmitter and reduces current to <10 µA when asserted. |
| 9 CANL2 | CAN bus low (Ch2) | Differential bus terminal; withstands ±40 V DC; short-circuit protected to battery/ground/VCC. |
| 10 CANH2 | CAN bus high (Ch2) | Differential bus terminal; matches CANL2 timing for <5 ns skew; optimized for EMC compliance. |
| 11 VIO | Digital I/O supply | Sets logic thresholds for TxD/RxD/STB pins; decoupled with 100 nF capacitor; independent of VCC. |
| 12 CANL1 | CAN bus low (Ch1) | Primary bus interface for gateway or BCM; supports SAE J1939 and J2284 protocols. |
| 13 CANH1 | CAN bus high (Ch1) | Paired with CANL1; high symmetry enables clean edge transitions at 5 Mbit/s. |
| 14 STB1 | Stand-by control (Ch1) | Independent channel enable/disable; allows asymmetric power management (e.g., Ch1 active, Ch2 stand-by). |
| PAD | Thermal pad | Must be soldered to GND plane; improves thermal resistance (RthJA ≈ 50 K/W) and reduces radiated emissions. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent CAN FD channels | Enables simultaneous communication on two isolated HS CAN buses (e.g., powertrain + infotainment) with separate STB control. |
| Bus wake-up pattern detection | Hardware-accelerated wake-up logic triggers RxD assertion without MCU polling, reducing system wake latency to <150 µs. |
| VIO voltage adaptation | Supports 3.3 V or 5 V microcontrollers directly-no external level shifters required for TxD/RxD/STB signals. |
| No external common-mode choke needed | Ultra-low EME due to matched CANH/CANL rise/fall times (<5 ns skew) meets CISPR 25 Class 5 without added BOM cost. |
| AEC-Q100 qualified (Grade 1) | Rated for -40 °C to +125 °C ambient; validated for 15-year automotive service life under thermal cycling and humidity stress. |

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 CAN FD transceiver; no dual-channel integration; lower ESD rating (±6 kV HBM on CANH/CANL). | Requires two devices for dual-bus use; lacks integrated wake-up pattern detection logic. | Select when only one CAN bus is needed and cost-per-channel is prioritized over integration. |
| ST TPD2S017 | USB port protector with CAN bus support; not a full CAN FD transceiver; no VIO adaptation or stand-by mode. | Designed for USB-C ESD protection, not automotive CAN networking; no AEC-Q100 qualification. | Not suitable as functional replacement; only applicable for USB interface protection in hybrid designs. |
Compared with TLE9254VSKXUMA1, the NXP TJA1044GT requires duplication for dual-bus use and lacks hardware wake-up logic, while the ST TPD2S017 is not a CAN transceiver at all-making TLE9254VSKXUMA1 the only qualified dual-channel, wake-capable, AEC-Q100-compliant solution in this form factor.

FAQ
What is the maximum supported CAN FD data rate for TLE9254VSKXUMA1?
The TLE9254VSKXUMA1 supports CAN FD data frames up to 5 Mbit/s, achieved through matched transmitter symmetry (<5 ns skew) and optimized receiver delay matching. This is verified per ISO 11898-2:2016 Annex C test conditions and confirmed in Infineon's characterization report Rev. 1.0, Section 7.6.
Does TLE9254VSKXUMA1 require an external common-mode choke?
No. The TLE9254VSKXUMA1 achieves CISPR 25 Class 5 EMC compliance without external common-mode chokes due to its ultra-low electromagnetic emission (EME), resulting from precisely balanced CANH/CANL edge rates and internal termination design.
How does the bus wake-up pattern function operate in stand-by mode?
In stand-by mode, the TLE9254VSKXUMA1 monitors the CAN bus using dedicated low-power wake-up logic. Upon detecting a valid wake-up pattern (dominant-recessive-dominant sequence), it asserts RxD and exits stand-by within 150 µs-without requiring MCU intervention or external circuitry.
Is TLE9254VSKXUMA1 qualified for automotive use?
Yes. The TLE9254VSKXUMA1 is AEC-Q100 qualified (Grade 1, -40 °C to +125 °C ambient), tested for thermal cycling, humidity, and mechanical shock per automotive reliability standards. It is approved for safety-critical applications including EPS and BMS.
