Product details
Overview
TLE82642EXUMA3 from Infineon Technologies is a monolithic Universal System Basis Chip (SBC) for automotive CAN-LIN gateway and body control applications. It integrates a high-speed CAN transceiver (ISO 11898-2/5 compliant, up to 1 MBaud), three LIN transceivers (LIN 2.1, up to 20 kBaud), three LDO regulators (Vcc1µC/Vcc2 @ 200 mA, Vcc3 @ up to 400 mA), SPI interface, watchdog/reset supervision, wake-up input, and four open-drain Limp Home outputs - all in a single PG-DSO-36-38 package.
For engineers reviewing the TLE82642EXUMA3 datasheet, TLE82642EXUMA3 pinout, TLE82642EXUMA3 application, or TLE82642EXUMA3 equivalent, key selection criteria include dual-supply LDO capability, configurable fail-safe Limp Home behavior, bus wake-up support across CAN/LIN, cyclic wake in Stop Mode, and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE82642EXUMA3 implements a state-machine-driven SBC architecture with hardware-configurable modes (Normal, Stop, Sleep, Flash) and software-controlled transitions via SPI. Its supervision subsystem includes a window watchdog (16–1024 ms programmable timeout), undervoltage reset generator with time-out on Vcc1µC, and interrupt management with timing filters to suppress noise-induced spurious signals.
It supports concurrent bus activity: HS-CAN operates at up to 1 MBaud with dedicated VccHSCAN supply and bus failure detection; each of the three LIN channels complies with LIN 2.1 and SAE J2602-2, with independent enable/disable and fault reporting via SPI status registers. The Limp Home logic uses dedicated internal supply and offers PWM (100 Hz, 20% duty) and side-indicator (1.25 Hz, 50% duty) outputs for safety-critical fallback operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| HS-CAN Data Rate | Up to 1 MBaud; enables real-time communication with ECUs in powertrain and chassis networks. |
| LIN Channels | 3 independent LIN 2.1 transceivers; supports multi-node body electronics (e.g., door modules, seat controls). |
| Vcc1µC Output | 5 V ±2%, 200 mA; powers external microcontroller with integrated pull-up reset output and UVLO time-out. |
| Watchdog Type | Configurable window watchdog (16–1024 ms); prevents firmware lockup with checksum-protected SPI configuration. |
| Limp Home Outputs | 4 open-drain outputs; provide fail-safe signaling (e.g., hazard flash, brake light override) during system fault. |
| Operating Temp | −40 °C to +150 °C ambient; qualified per AEC-Q100 Grade 0 for under-hood use without derating. |
| ESD Robustness | 8 kV HBM on CANH/CANL/SPLIT and LIN bus pins; ensures reliability in manufacturing and field environments. |
Pinout & Package

| Vcc3 | Adjustable LDO output | 5 V ±4% with external PNP pass transistor; current limited by shunt resistor (e.g., 400 mA with 220 mΩ). |
| CANH / CANL | HS-CAN differential bus interface | ISO 11898-2/5 compliant; short-circuit proof to battery and GND; supports bus wake-up. |
| LIN1–LIN3 | Three LIN bus I/Os | Each supports LIN 2.1 protocol, 20 kBaud data rate, and individual fault detection via SPI. |
| WK | Wake-up input | Bi-level sensitive; enables wake from Stop/Sleep modes via external signal or bus activity. |
| RESET | Reset output | Open-drain active-low reset with integrated pull-up; asserts on UVLO, watchdog timeout, or SPI command. |
| SPI_CS / MOSI / MISO / SCLK | 16-bit SPI interface | Full-duplex serial control and status monitoring; supports corrupted-data detection and CRC-like checksums. |
| LH1–LH4 | Limp Home outputs | Open-drain, internally powered; configurable for PWM (100 Hz) or side-indicator (1.25 Hz) safety signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Triple LIN + HS-CAN integration | Reduces BOM count and PCB area vs. discrete transceivers; eliminates inter-chip timing skew in gateways. |
| Four configurable Limp Home outputs | Enables ASIL-B–compatible fail-safe behavior (e.g., brake light override, hazard activation) without external logic. |
| Dual independent 5 V LDOs (200 mA each) | Allows isolated power domains: one for MCU, one for CAN PHY - improving noise immunity and fault containment. |
| Cyclic wake-up in Stop Mode | Permits periodic self-check without external timer; extends battery life in always-on vehicle modules. |
| Bus failure detection (CAN/LIN) | Reports short-to-battery, short-to-ground, and open-circuit faults via SPI status register for diagnostic logging. |
Applications
| Body Control Module (BCM) | Central Gateway ECU |
|---|---|
|
Use Scenario: Centralized control of lighting, windows, locks, and mirrors in modern passenger vehicles. IC Role / Device Role / Timing Role: SBC provides power (Vcc1µC/Vcc2), communication (3× LIN + CAN), and safety fallback (LH1–LH4) for MCU and peripheral drivers. Use Value: Single-chip integration reduces component count by ≥7 discrete ICs while enabling coordinated Limp Home responses during MCU failure. |
Use Scenario: Protocol translation and message routing between CAN (powertrain/chassis) and LIN (body/sensor) subnetworks. IC Role / Device Role / Timing Role: Acts as bridge controller: HS-CAN handles high-priority messages; three LIN ports manage distributed low-cost nodes (e.g., HVAC actuators). Use Value: Concurrent bus operation avoids arbitration delays; SPI allows runtime reconfiguration of LIN node addressing and CAN filter settings. |
| Roof Module Controller | Seat Control Unit |
|
Use Scenario: Sunroof, panoramic roof, and interior lighting control with integrated anti-pinch and position feedback. IC Role / Device Role / Timing Role: Supplies MCU and motor drivers (via Vcc3), monitors CAN commands, wakes on LIN sensor updates, and triggers LH outputs on overtemperature. Use Value: Vcc3's adjustable current limit (up to 400 mA) supports external PNP-based motor biasing; WK pin enables precise wake timing from LIN position sensors. |
Use Scenario: Memory seat positioning, heating/ventilation, and occupancy sensing in premium vehicle seating systems. IC Role / Device Role / Timing Role: Powers MCU and LIN-connected seat sensors/actuators; uses Limp Home outputs to force safe seat position (e.g., full upright) on critical fault. Use Value: Four LH outputs allow independent control of seat motor direction, heater disable, and warning indicators - meeting ISO 26262 ASIL-B requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar universal SBC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9471-2QX | Single LIN channel, no Limp Home outputs; adds SENT interface and enhanced diagnostics. | Targeted at powertrain sensor interfaces, not body/gateway applications requiring multiple LIN buses. | Select when SENT sensor integration outweighs need for LIN scalability and fail-safe outputs. |
| MC33816 | Two LIN channels, no Vcc3 regulator; includes analog inputs and enhanced watchdog with window violation detection. | Optimized for mid-tier body controllers where cost and analog monitoring outweigh triple-LIN demand. | Select when analog sensor monitoring (e.g., temperature, voltage) is required alongside dual-LIN and CAN. |
Compared with TLE9471-2QX and MC33816, the TLE82642EXUMA3 uniquely delivers triple-LIN support, four Limp Home outputs, and Vcc3 programmability - making it the only choice for scalable, safety-aware automotive gateways requiring ≥3 LIN domains and coordinated fail-safe signaling.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The TLE82642EXUMA3 has a maximum junction temperature of +150 °C, validated per AEC-Q100 Grade 0. Thermal derating is not required up to this limit when mounted on a 4-layer PCB with 2 oz copper and ≥2 cm² thermal pad area. The device includes internal overtemperature protection that forces Safe State entry above 165 °C.
Can the three LIN transceivers operate simultaneously at different baud rates?
Yes - each LIN channel (LIN1–LIN3) supports independent baud rate configuration via SPI register writes. Valid ranges are 1–20 kBaud for standard operation and up to 115 kBaud in LIN Flash Mode. No hardware conflict arises because each transceiver has dedicated TX/RX logic and bus drivers.
How does the Limp Home output behavior change during a Vcc1µC undervoltage event?
During Vcc1µC undervoltage, the Limp Home outputs remain active and retain their last configured state (PWM or side-indicator mode) because they are powered by a dedicated internal supply rail decoupled from Vcc1µC. This ensures fail-safe signaling continues even if the MCU supply collapses.
Is the HS-CAN transceiver compatible with CAN FD physical layer requirements?
No - the TLE82642EXUMA3 implements a classical HS-CAN transceiver compliant with ISO 11898-2 and ISO 11898-5 only. It does not support CAN FD's higher bit rates (>1 MBaud) or flexible data phase; its maximum data rate is 1 MBaud with fixed dominant/recessive timing.
