TLE8264EXUMA1

Overview

The TLE8264EXUMA1 is a System Basis Chip (SBC) designed for automotive body controller and gateway applications. It integrates a High-Speed CAN transceiver compliant with ISO11898-2/5, up to three LIN transceivers supporting LIN2.1/J26022 standards, and two Low Dropout Voltage Regulators (LDOs). The device features a 16-bit Serial Peripheral Interface (SPI) for configuration and diagnostics, alongside integrated fail-safe functions including watchdog circuits and Limp Home outputs. Manufactured in an exposed pad DSO package, it supports low power modes and wake-up via bus messages or monitoring inputs.

Feature Summary

• Integrated HS-CAN transceiver and up to 3 LIN transceivers
• Dual LDOs providing 5V output up to 200mA
• 16-bit SPI interface for control and diagnostic monitoring
• Automotive grade qualification with integrated fail-safe and Limp Home outputs

Applications

• Body Control Modules (BCM)
• Gateway applications
• HVAC Control Modules
• Door Modules with lock and mirror control

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm pinout compatibility and feature set variations. Confirm that the PG-DSO-36-38 package matches the target PCB footprint requirements. Ensure the component meets the required automotive quality standards for the intended deployment environment.

Selection Notes

Select this component when a single IC solution is required to manage both CAN and LIN communication alongside power regulation. The integrated LDOs reduce external component count for 5V supply generation. Consider the 16-bit SPI diagnostic capabilities if detailed system monitoring is necessary for the application architecture.

Part Context

This part belongs to the TLE8264 SBC family from Infineon Technologies. Family members share identical software functionality and hardware features, differing primarily in the number of LIN cells and Limp Home Outputs available. This specific variant provides the standard configuration for high-feature body controllers.

Replacement Considerations

Direct replacements within the same family may exist but will differ in the quantity of LIN transceivers or Limp Home outputs. Verify functional equivalence regarding the specific bus interfaces and regulator capacities before substitution.
