Product details
Overview
TLE82632EXUMA1 from Infineon Technologies is a universal automotive System Basis Chip (SBC) integrating HS-CAN transceiver, dual LIN transceivers, three LDO regulators (Vcc1µC/Vcc2/Vcc3), watchdog, reset, wake-up, and limp-home circuitry in a single PG-DSO-36-38 package. It delivers 200 mA at 5 V ±2% on Vcc1µC and Vcc2, supports CAN up to 1 MBaud and LIN up to 20 kBaud (115 kBaud in flash mode), and operates across −40 °C to +150 °C ambient for body control modules and gateway ECUs.
For engineers reviewing the TLE82632EXUMA1 datasheet, TLE82632EXUMA1 pinout, TLE82632EXUMA1 application, or TLE82632EXUMA1 equivalent, key selection criteria include dual-LIN support with independent configuration, three dedicated Limp Home outputs with PWM and side-indicator modes, SPI-configurable watchdog timeout (16–1024 ms), and AEC-Q100 qualification for permanent-battery automotive systems.
Technical Context
The TLE82632EXUMA1 implements a hierarchical state machine with Stop, Sleep, Normal, and Flash modes, enabling ultra-low quiescent current (≤30 µA in Stop Mode) while retaining bus wake-up capability via CAN message, LIN message, or bi-level WK input. Its supervision logic includes a window watchdog with checksum-protected SPI configuration and configurable reset inhibition during development.
All three LDOs are internally current-limited and thermally protected: Vcc1µC and Vcc2 supply external microcontrollers and RF receivers at 5 V ±2%, while Vcc3 supports external CAN transceivers via external PNP transistor with shunt-resistor-set current limit (up to 400 mA with 220 mΩ). The SPLIT pin enables common-mode noise suppression on the CAN bus.
Key Specifications

Use Scenario: Centralized control of lighting, windows, locks, and mirrors in modern passenger vehicles. IC Role / Device Role / Timing Role: System Basis Chip providing regulated power, CAN/LIN connectivity, watchdog supervision, and fail-safe limp-home signaling. Use Value: Integrates six discrete functions (CAN transceiver, dual LIN, triple LDO, watchdog, reset, wake-up) into one AEC-Q100-qualified device - reducing BOM count, PCB area, and validation effort. |
Use Scenario: Distributed control unit inside vehicle door managing window lift, mirror adjustment, and interior lighting. IC Role / Device Role / Timing Role: Dual-LIN master coordinating with seat, mirror, and switch modules; Vcc1µC powers local MCU; Limp Home drives LED indicators during fault conditions. Use Value: Enables standalone operation with battery-backed low-power Stop Mode (≤30 µA) and reliable wake-up via LIN command or mechanical switch on WK pin. |
| Gateway ECU | Roof Module Controller |
|
Use Scenario: In-vehicle network bridge connecting CAN FD backbone with LIN subnetworks (e.g., sunroof, HVAC, seat controls). IC Role / Device Role / Timing Role: HS-CAN transceiver handles high-priority messages; dual LIN interfaces manage multiple low-cost sensor/actuator clusters; SPI enables real-time status reporting to host processor. Use Value: Supports concurrent CAN and LIN traffic with independent error handling - prevents bus fault propagation between domains and maintains gateway uptime. |
Use Scenario: Roof-mounted module controlling panoramic sunroof, interior ambient lighting, and rain sensor wipers. IC Role / Device Role / Timing Role: Primary power manager (Vcc1µC/Vcc2) and LIN master for sunroof motor and LED drivers; Limp Home outputs drive roof-status LEDs during MCU failure. Use Value: Triple LDO architecture supplies isolated 5 V rails to MCU, motor driver, and lighting ICs - eliminating cross-talk and enabling individual overcurrent shutdown. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9471-3ES | Single-LIN SBC with integrated 3.3 V MCU supply and ASIL-B functional safety support - lacks second LIN channel and dedicated Vcc3 output. | Targeted at entry-level gateways requiring ISO 26262 compliance but not dual-LIN topology. | Select when ASIL-B diagnostics and 3.3 V MCU supply are mandatory, and dual-LIN is unnecessary. |
| TLE9263-2QX | Pin-compatible successor with extended temperature range (−40 °C to +175 °C), enhanced ESD (12 kV), and improved Vcc3 current capability (500 mA). | Designed for next-gen electric vehicle architectures requiring higher thermal margin and stronger EMC robustness. | Select for new designs targeting >15-year service life, under-hood placement, or EV traction inverter proximity. |
Compared with TLE82632EXUMA1, TLE9263-2QX offers higher thermal resilience and ESD rating for demanding EV applications, while TLE9471-3ES trades dual-LIN capability for ASIL-B safety features - making the original optimal for cost-sensitive dual-LIN body electronics where legacy qualification suffices.

FAQ
What is the maximum allowable input voltage on VccHSCAN?
VccHSCAN accepts 4.5 V to 5.5 V per the datasheet's functional range specification. Exceeding 5.5 V risks permanent damage to the HS-CAN transceiver block. This rail must be independently filtered and decoupled from Vcc1µC to prevent coupling of CAN bus transients into the MCU supply domain.
Can the two LIN transceivers operate simultaneously on different baud rates?
Yes - LIN1 and LIN2 are fully independent, each supporting programmable baud rates up to 20 kBaud (or 115 kBaud in Flash Mode) via separate SPI registers. This enables concurrent communication with heterogeneous LIN slaves, such as a seat control module on LIN1 and a mirror module on LIN2, without timing conflict.
How is the Limp Home output behavior configured?
Limp Home mode is selected via hardware pins (LHSEL0/LHSEL1) and SPI-controlled register bits. The three outputs support four modes: OFF, 1.25 Hz side-indicator (50% duty), 100 Hz PWM (20% duty), or direct MCU-controlled. No firmware is required to activate basic fail-safe signaling - it operates autonomously upon internal fault detection.
Does TLE82632EXUMA1 support CAN FD?
No - the integrated transceiver complies only with ISO 11898-2 and ISO 11898-5 for classical HS-CAN (up to 1 MBaud). It does not implement CAN FD arbitration or data-phase bit-rate switching. For CAN FD gateway applications, pairing with an external CAN FD controller (e.g., TCAN4550) is required.
