TLE9842QXXUMA1

Overview

The Infineon TLE9842QXXUMA1 is an automotive-grade microcontroller featuring a 32-bit Arm Cortex-M0 core operating at up to 25 MHz. It integrates 36 KB of flash memory, 2 KB of RAM, and an internal LIN transceiver. The device supports a single power supply from 3.0 V to 28 V and includes an integrated 5 V voltage regulator for external loads. Key peripherals include two low-side switches with PWM capability, one high-side switch, an 8-bit ADC with 7 channels, and a 10-bit ADC with 13 channels. It is qualified under AEC-Q100 standards.

Feature Summary

• Arm Cortex-M0 core with 25 MHz clock frequency
• Integrated LIN transceiver and bootstrap loader (LIN BSL)
• Power management unit with 5 V external load regulator
• Dual ADC configuration: 8-bit (7 channels) and 10-bit (13 channels)

Applications

• Window lift systems

Procurement Notes

Verify the specific package variant (VQFN-48-31, -37, or -79) against design requirements, as availability varies by step. Confirm that the ordering suffix corresponds to the desired pinout and manufacturing lot. Ensure compliance with moisture sensitivity levels during storage and handling procedures.

Selection Notes

Select this component for applications requiring integrated motor control and LIN communication in a compact form factor. Verify that the 36 KB flash capacity meets firmware size requirements. Check if the available GPIO count and switch configurations align with the target hardware interface needs.

Part Context

This part belongs to the MOTIX™ TLE9842QX family of microcontrollers designed for embedded power applications. It serves as a specialized solution for automotive body electronics, combining processing capabilities with power switching functions to reduce system complexity and component count.

Replacement Considerations

Check for updated engineering steps (AE vs UD) within the same TLE9842QX series. Verify pin-to-pin compatibility if considering variants with different package markings or minor electrical parameter adjustments.
