Product details
Overview
TLE8264EXUMA1 from Infineon Technologies is a high-integration CAN FD transceiver with integrated voltage regulator (5 V, 150 mA), watchdog, and windowed timer, designed for automotive body electronics and chassis control units. It supports data rates up to 5 Mbit/s, operates from 4.5 V to 28 V supply, and features bus fault protection up to ±70 V.
For engineers reviewing the TLE8264EXUMA1 datasheet, TLE8264EXUMA1 pinout, TLE8264EXUMA1 application, or TLE8264EXUMA1 equivalent, key selection criteria include CAN FD compliance, integrated power management, wake-up sensitivity (±150 mV), thermal shutdown behavior, and ISO 11898-2:2016 conformance.
Technical Context
The TLE8264EXUMA1 implements a fully compliant ISO 11898-2:2016 physical layer interface with dominant timeout protection and silent mode for ECU sleep/wake coordination. Its integrated 5 V/150 mA LDO powers external microcontrollers while maintaining independent enable control and undervoltage lockout (UVLO at 4.5 V).
It includes a programmable windowed watchdog with reset output and configurable timeout windows (16 ms to 2.1 s), plus a dedicated wake-up input (WAKE) with ±150 mV threshold and hysteresis, enabling low-power network monitoring without MCU intervention.
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. |
| Supply Voltage Range | 4.5 V to 28 V - supports direct battery connection across 12 V and 24 V automotive systems. |
| Integrated LDO Output | 5 V ±2%, 150 mA - powers MCU and peripheral ICs without external regulator. |
| Bus Fault Protection | ±70 V - withstands load dump and jump-start transients per ISO 7637-2. |
| Wake-up Threshold | ±150 mV - detects CAN bus activity during deep sleep with minimal current draw (15 µA typical). |
| Watchdog Timeout Range | 16 ms to 2.1 s - configurable windowed watchdog prevents runaway code while allowing valid software delays. |
Pinout & Package
Package: PG-DSO-36 (36-pin exposed pad SOIC), RoHS-compliant, thermally enhanced for under-hood operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Main supply input | Accepts 4.5–28 V; powers internal circuitry and LDO input. |
| VIO | I/O supply reference | Supplies logic-level interface (3.3 V or 5 V) for MCU side signals. |
| VOUT | LDO regulated output | Delivers stable 5 V ±2% at up to 150 mA for external loads. |
| CANH / CANL | Differential bus interface | Compliant ISO 11898-2 physical layer outputs with slew-rate control and fault protection. |
| WAKE | Wake-up input | Edge-sensitive input detecting bus activity; triggers wake event with ±150 mV threshold. |
| EN | Enable control | Active-high input enabling transceiver and LDO; pulls down to disable entire device. |
| RESET | Watchdog reset output | Open-drain output asserting low on watchdog timeout or UVLO condition. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 5 V/150 mA LDO | Reduces BOM count by eliminating external regulator; supports MCU and CAN controller power domains. |
| Programmable windowed watchdog | Prevents system hang without false resets; configurable via external resistor network. |
| Silent mode with wake-up detection | Enables ultra-low-power sleep (15 µA) while retaining bus activity monitoring capability. |
| ±70 V bus fault protection | Eliminates need for external TVS diodes in most automotive environments per ISO 7637-2 Pulse 5a/b. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver with integrated power management applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP TJA1044T | No integrated LDO or watchdog; requires external 5 V supply and separate supervision IC. | Lower integration level; suitable where MCU already has dedicated power and watchdog resources. | Select when cost-per-node is prioritized over BOM reduction and board space. |
| Renesas R7F701028 | Microcontroller with embedded CAN FD controller and LDO - not a transceiver; lacks physical layer compliance and bus protection. | Requires external CAN transceiver (e.g., R7F701028 + R7F701028); no single-chip solution. | Choose only if migrating to SoC-based architecture with existing transceiver reuse strategy. |
Compared with TJA1044T and R7F701028, the TLE8264EXUMA1 uniquely combines full CAN FD PHY, 5 V/150 mA LDO, and windowed watchdog in one DSO-36 package-enabling true single-chip ECU node design with reduced validation effort and higher functional safety readiness.

FAQ
What is the maximum CAN FD data rate supported by the TLE8264EXUMA1?
The TLE8264EXUMA1 supports CAN FD data rates up to 5 Mbit/s in fast-phase transmission, compliant with ISO 11898-1:2015 and ISO 11898-2:2016. This enables high-throughput diagnostics, firmware updates, and real-time sensor data streaming in modern automotive networks.
Does the TLE8264EXUMA1 require an external crystal or clock source?
No. The TLE8264EXUMA1 is a physical-layer transceiver only and does not contain or require an internal oscillator or external crystal. Clocking is provided entirely by the connected CAN controller; the transceiver operates synchronously with incoming bit timing from the controller.
How does the wake-up function operate during sleep mode?
In silent mode, the TLE8264EXUMA1 draws 15 µA while monitoring the CAN bus via its WAKE pin. A differential voltage swing exceeding ±150 mV on CANH/CANL triggers a wake event, pulling the WAKE output high to alert the MCU-enabling sub-100 µs response time from deep sleep.
Is the integrated LDO output short-circuit protected?
Yes. The 5 V LDO output features foldback current limiting and thermal shutdown. Under short-circuit conditions, output current is reduced to ~50 mA, and device temperature rise triggers automatic shutdown at 165 °C, with automatic recovery after cooldown.
