Product details
Overview
TLE9254VLCXUMA1 from Infineon is a high-speed dual-channel CAN FD transceiver compliant with ISO 11898-2:2016, designed for automotive HS CAN networks. It supports data rates up to 5 Mbit/s, features bus wake-up pattern detection, achieves <10 µA quiescent current per channel in stand-by mode, and operates across extended VCC (4.5–6.0 V) and VIO (3.0–6.0 V) supply ranges. It is deployed in body control modules and gateway systems requiring robust ESD immunity and low EME.
For engineers reviewing the TLE9254VLCXUMA1 datasheet, TLE9254VLCXUMA1 pinout, TLE9254VLCXUMA1 application, or TLE9254VLCXUMA1 equivalent, key selection criteria include dual-channel CAN FD timing symmetry, bus wake-up sensitivity, stand-by current consumption, and AEC-Q100 qualification for automotive deployment.
Technical Context
The TLE9254VLCXUMA1 integrates two independent high-speed CAN FD transceivers sharing a common VIO rail and separate STB/TxD/RxD/CANH/CANL terminals per channel. Its transmitter delivers <±1% differential output symmetry at 5 Mbit/s, while the receiver employs dual-path architecture-normal-mode and low-power wake-up path-with programmable wake-up pattern filtering.
It implements fail-safe functions including TxD timeout (programmable via external RC), overtemperature shutdown (>150°C), undervoltage lockout on VCC and VIO, and short-circuit protection to battery, ground, and VCC. The device supports voltage-adaptive logic I/O via VIO and maintains passive bus behavior during power-off.
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 Current (per channel) | <10 µA typical - extends battery life in always-on automotive modules like gateways and BCMs. |
| Common Mode Range | ±40 V - ensures reliable operation under severe electromagnetic interference in vehicle harnesses. |
| 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 - allows direct interfacing with both 3.3 V and 5 V microcontrollers without level shifters. |
| Operating Junction Temp | -40°C to +150°C - qualified for under-hood and transmission-control applications per AEC-Q100 Grade 0. |
| EME Performance | No external common-mode choke required - reduces BOM cost and board space in compact modules. |
Pinout & Package
The TLE9254VLCXUMA1 is housed in a PG-TSON-14 (leadless, thermally enhanced) package with exposed thermal pad, RoHS-compliant and halogen-free, supporting AOI solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TxD1 / TxD2 | Transmit Data Input | CMOS-level input with internal pull-up to VCC; dominant state = low; controls CANH/CANL driver state. |
| RxD1 / RxD2 | Receive Data Output | CMOS-level open-drain output; dominant = low; indicates bus state; doubles as wake-up indicator in stand-by. |
| CANH1 / CANH2 | CAN Bus High I/O | Differential high-side bus terminal; outputs 2.75–3.75 V in recessive state; drives dominant to ~3.5 V above CANL. |
| CANL1 / CANL2 | CAN Bus Low I/O | Differential low-side bus terminal; outputs 1.25–2.25 V in recessive state; driven to ~1.5 V below CANH in dominant. |
| STB1 / STB2 | Stand-by Control Input | Active-high enable; internal pull-up to VCC; asserts stand-by mode when high, reducing current to <10 µA per channel. |
| VCC | Transmitter Supply | 4.5–6.0 V analog supply for CAN drivers; requires 100 nF decoupling to GND; can be powered down in stand-by. |
| VIO | Digital Interface Supply | 3.0–6.0 V supply for logic interface; sets TxD/RxD voltage thresholds; remains active during stand-by. |
| GND1 / GND2 | Analog Ground Returns | Separate ground pins per channel; must be connected to same PCB ground plane to minimize ground bounce. |
| PAD | Thermal Pad | Exposed copper pad on bottom; must be soldered to PCB thermal plane (GND-connected) for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent CAN FD channels | Enables simultaneous communication on two isolated HS CAN buses (e.g., powertrain + body domain) without MCU resource contention. |
| Bus wake-up pattern detection | Hardware-filtered wake-up recognition on CANH/CANL without CPU involvement, reducing system latency and power. |
| Low EME emission profile | Meets CISPR 25 Class 5 limits without external common-mode chokes, simplifying layout and lowering BOM cost. |
| TxD timeout protection | Prevents bus lock-up by disabling transmitter after configurable timeout (via external RC), protecting network integrity. |
| AEC-Q100 Grade 0 qualification | Validated for operation from -40°C to +150°C junction temperature, meeting requirements for engine bay and transmission control. |

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/3 | Single-channel CAN FD transceiver; no dual-channel integration; lower ESD rating (±8 kV HBM on CANH/L). | Requires two devices for dual-bus operation; lacks integrated bus wake-up pattern detection logic. | Select when only one CAN FD bus is needed and cost-per-channel is prioritized over integration. |
| ST TLE6250G | Legacy high-speed CAN (non-FD); max 1 Mbit/s; no VIO pin; fixed 5 V logic interface; no stand-by wake-up pattern support. | Not suitable for CAN FD data frames or 3.3 V microcontrollers; lacks low-power wake-up capability. | Select only for legacy CAN 2.0B designs where FD bandwidth and ultra-low stand-by current are not required. |
Compared with TJA1044GT/3 and TLE6250G, the TLE9254VLCXUMA1 uniquely delivers dual-channel CAN FD at 5 Mbit/s with hardware wake-up pattern detection, sub-10 µA stand-by current, and flexible VIO-based logic interfacing - making it optimal for next-generation automotive domain controllers.

FAQ
What is the maximum supported CAN FD data rate for TLE9254VLCXUMA1?
The TLE9254VLCXUMA1 supports CAN FD data frames up to 5 Mbit/s, enabled by its high transmitter symmetry (<±1%) and optimized receiver delay matching. This performance is validated per ISO 11898-2:2016 and confirmed in Infineon's characterization reports across temperature and voltage ranges.
Does TLE9254VLCXUMA1 require an external common-mode choke?
No. Due to its very low electromagnetic emission (EME) profile across 1–100 MHz, the TLE9254VLCXUMA1 meets CISPR 25 Class 5 limits without an external common-mode choke - a design advantage verified in Infineon's EMC test reports and application notes.
How does the bus wake-up pattern function operate?
The wake-up pattern detector monitors CANH/CANL for standardized dominant-recessive sequences (e.g., 0x55 or 0xAA). Upon match, it asserts RxD low to signal wake-up while remaining in stand-by; no MCU intervention is required until full channel activation.
Is TLE9254VLCXUMA1 compatible with both 3.3 V and 5 V microcontrollers?
Yes. Its VIO pin accepts 3.0–6.0 V, allowing direct interface with 3.3 V or 5 V MCUs. Logic thresholds scale with VIO, ensuring correct TxD sampling and RxD output levels without external level-shifting circuitry.
