Product details

Overview

TLE9255WLCXUMA1 from Infineon is a high-speed CAN transceiver with partial networking and CAN FD tolerance, designed as the physical layer interface between microcontrollers and HS CAN buses in automotive ECUs. It supports data rates up to 5 MBit/s (CAN FD), complies with ISO 11898-2:2016, features ±10 kV ESD robustness, operates down to 26 µA quiescent current in Sleep Mode, and includes SPI-configurable wake-up frame detection and fail-safe functions including overtemperature shutdown.

For engineers reviewing the TLE9255WLCXUMA1 datasheet, TLE9255WLCXUMA1 pinout, TLE9255WLCXUMA1 application, or TLE9255WLCXUMA1 equivalent, key selection criteria include CAN FD tolerance without MCU upgrade, selective wake-up capability with 29-bit ID + 64-bit data matching, independent VCC/VIO supply for mixed-voltage systems, and AEC-Q100 qualification for under-hood deployment.

Technical Context

The TLE9255WLCXUMA1 implements a dual-supply architecture with separate VCC (2.7–5.5 V), VIO (3.3 V or 5 V), and VBAT (5–27 V) rails, enabling battery-independent operation and microcontroller voltage flexibility. Its internal state machine supports four operational modes-Normal, Receive-only, Stand-by, and Sleep-with sub-modes like Selective Wake for message-filtered wake-up.

It integrates a configurable SPI interface (up to 4 MHz) for real-time control of mode transitions, wake-up pattern definition, status reporting, and error flag monitoring (e.g., CANTO, SYNC, SWK_ACTIVE). The transceiver provides automatic bus biasing per ISO 11898-2:2016 and CAN short-circuit protection to ground, battery, and VCC.

Key Specifications

Parameter	Value and Actual Design Meaning
Bus Data Rate	Up to 5 MBit/s CAN FD - enables payload expansion and faster diagnostics without changing MCU firmware.
Quiescent Current (Sleep)	≤26 µA over full temperature range - extends battery life in always-on vehicle networks.
ESD Robustness	±10 kV HBM per IEC 61000-4-2 - eliminates need for external TVS diodes in most automotive layouts.
Wake-up Filter Time	0.5 µs < t_Filter < 1.8 µs - meets global OEM timing requirements for reliable low-power bus monitoring.
VIO Supply Range	3.3 V or 5 V selectable - interoperates with legacy 5 V and modern 3.3 V microcontrollers without level shifters.
Operating Temperature	−40 °C to +150 °C - qualified for engine compartment and transmission control unit placement.
Fail-Safe Features	TxD timeout, overtemperature shutdown/warning, undervoltage detection on VBAT/VCC/VIO - prevents erroneous bus behavior during power faults.

Pinout & Package

Package: PG-TSON-14 (exposed thermal pad), RoHS-compliant, moisture sensitivity level 3. Thermal resistance R_thJA = 50 K/W typical.

Pin/Terminal	Circuit Role	Design Meaning
VCC	Main supply input	2.7–5.5 V logic supply; powers internal circuitry when VBAT is disconnected.
VBAT	Battery supply input	5–27 V direct battery connection; enables wake-up and INH control during ignition-off.
VIO	I/O reference voltage	Selectable 3.3 V or 5 V reference for SPI and logic pins; matches MCU I/O voltage.
CANH / CANL	Differential bus outputs	High-symmetry drivers meeting ISO 11898-2:2016 common-mode range and emission limits.
RxD / TxD	Controller interface	CMOS-level signals connecting to MCU CAN controller; TxD includes timeout safety logic.
INH	Supply enable output	Open-drain output controlling external LDO or DC/DC; asserts during undervoltage or overtemperature.
WAKE	Local wake-up input	Active-low digital input triggering mode transition from Sleep/Stand-by without bus activity.
CSN / SCK / MOSI / MISO	SPI interface	4-wire SPI (3.3/5 V tolerant) for configuring wake-up IDs, reading error flags, and managing modes.

Key Features

Feature	Design Value
CAN FD Tolerance	Receives and filters CAN FD frames while operating with non-CAN FD MCUs - avoids costly MCU replacement in legacy designs.
Selective Wake Sub-Mode	Monitors up to 29-bit identifier and 64-bit data field for wake-up frames - reduces false triggers in multi-node networks.
Independent VCC/VIO Supplies	Decouples logic supply from I/O reference - allows mixed-voltage system integration without external level shifters.
Automatic Bus Biasing	Internal termination and biasing compliant with ISO 11898-2:2016 - eliminates external resistors and saves PCB space.
Integrated Fail-Safe Logic	TxD timeout, overtemperature warning/shutdown, and multi-rail undervoltage detection - ensures deterministic bus behavior during fault conditions.

Applications

Use Scenario: Real-time engine torque and transmission gear position exchange between ECU and TCU at 2–5 MBit/s.

IC Role / Device Role / Timing Role: CAN FD-capable physical layer supporting larger diagnostic payloads and faster control loop updates.

Use Value: Doubles effective bandwidth vs classical CAN - accelerates flash programming and active calibration during service.

Advanced Driver Assistance System (ADAS) ECU

Electric Vehicle Battery Management System (BMS)

Use Scenario: Reliable sensor fusion data exchange among radar, camera, and domain controller under EMI-heavy conditions.

IC Role / Device Role / Timing Role: High-immunity transceiver with ±10 kV ESD rating and wide common-mode range (−2 V to 14 V).

Use Value: Maintains communication integrity near high-current inverters and switching regulators - eliminates intermittent CAN errors.

Use Scenario: Cell voltage and temperature reporting from battery packs to central BMS across long harnesses.

IC Role / Device Role / Timing Role: Short-circuit proof transceiver with CANH/CANL protection to ground, battery, and VCC rails.

Equivalent & Alternatives

The following parts are listed as comparable options for similar HS CAN transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP TJA1044T	Supports CAN FD up to 5 MBit/s but lacks SPI-configurable wake-up frame filtering; uses fixed hardware wake-up pattern.	Requires external logic for selective wake; not suitable for OEMs requiring programmable 29-bit ID + 64-bit data match.	Prefer when cost-sensitive designs accept fixed wake-up behavior and omit SPI dependency.
ST TLE6250G	Classical CAN only (1 MBit/s max); no CAN FD support; no SPI interface; basic wake-up via WUP only.	Cannot process CAN FD frames or enable selective wake; limited to legacy networks without partial networking.	Only viable for brownfield upgrades where CAN FD and advanced wake-up are unnecessary.

Compared with TJA1044T and TLE6250G, the TLE9255WLCXUMA1 uniquely combines CAN FD tolerance, SPI-driven selective wake-up configuration, and triple-rail supply management - making it the only option for new AEC-Q100-compliant designs requiring both future-proof bandwidth and precise low-power network control.

FAQ

Does TLE9255WLCXUMA1 require an external common-mode choke?

No. Its high-symmetry CANH/CANL driver design achieves very low electromagnetic emission across a wide frequency band, satisfying CISPR 25 Class 5 requirements without needing an external common-mode choke - reducing BOM cost and PCB area in automotive layouts.

Can TLE9255WLCXUMA1 operate without VBAT connected?

Yes. The device supports VCC-only operation (2.7–5.5 V) for logic and SPI functions, with VBAT optional. When VBAT is unconnected, INH remains inactive and wake-up via bus activity is disabled, but local wake-up (WAKE pin) and normal CAN communication remain functional.

What is the maximum allowed SPI clock frequency?

The SPI interface supports clock frequencies up to 4 MHz, compatible with most automotive microcontrollers. Timing parameters (t_CSH, t_CSL, t_DSU, t_HD) are specified in the datasheet for setup/hold compliance across −40 °C to +150 °C.

How does the TLE9255WLCXUMA1 handle CAN bus short circuits?

It provides full short-circuit protection on CANH and CANL to ground, battery, and VCC. Internal current limiting and thermal foldback prevent damage during sustained shorts, and the transceiver automatically recovers once the fault clears - no reset or reconfiguration required.
