TLE8262-2E

Overview

The TLE8262-2E is a Universal System Basis Chip (SBC) from the HERMES family, designed for automotive body controller and gateway applications. It integrates a high-speed CAN transceiver compliant with ISO 11898-2/5 and SAE J2284, supporting data rates up to 1 MBaud. The device includes one LIN transceiver conforming to LIN 2.1 and ISO 9141 standards, operating at up to 20 kBaud. Power management features include three low-dropout voltage regulators: Vcc1µC (200 mA), Vcc2 (200 mA), and Vcc3 (up to 400 mA). Supervision functions comprise a configurable watchdog timer (16 ms to 1024 ms), reset generation, and Limp Home outputs for safety-critical signaling.

Feature Summary

• Integrated HS-CAN transceiver with bus fault protection and wake-up capability
• Single LIN transceiver supporting LIN 2.1 and ISO 9141 protocols
• Three LDO voltage regulators (Vcc1µC, Vcc2, Vcc3) with current limits up to 400 mA
• Configurable Window or Time-out Watchdog Timer with reset output

Applications

• Automotive Body Control Modules (BCM)
• Gateway applications in vehicle networks
• Safety-related control units requiring Limp Home functionality

Procurement Notes

Verify package marking 'TLE8262-2E' on PG-DSO-36-38 components. Confirm RoHS compliance and AEC-Q100 qualification status through official Infineon documentation. Ensure ordering suffixes match specific tape-and-reel requirements if applicable.

Selection Notes

Select this model for applications requiring exactly one LIN channel alongside HS-CAN. Compare with TLE8263-2E for two LIN channels or TLE8264-2E for three LIN channels. Verify voltage regulator current requirements against the 200 mA limit of Vcc1µC and Vcc2, noting that Vcc3 supports higher currents via external PNP transistor configuration.

Part Context

Part of the scalable HERMES SBC family, sharing identical software functionality and hardware features across variants. Differentiation within the family is primarily based on the number of integrated LIN cells (0 to 3) and the count of Limp Home outputs.

Replacement Considerations

Direct functional substitutes within the same family include TLE8263-2E (2 LIN channels) and TLE8264-2E (3 LIN channels). Non-family replacements require verification of pin compatibility and interface specifications.
