TLE9832QVXUMA1

Overview

The TLE9832QVXUMA1 is an automotive microcontroller featuring a high-performance XC800 core compatible with the standard 8051 architecture, operating at up to 40 MHz. It integrates 36 kByte of Flash memory and includes one High Side Switch and two Low Side Switches for direct load driving. The device incorporates a LIN transceiver compliant with LIN 1.3/2.0/2.1 standards, alongside an 8-channel 10-bit ADC (ADC1) and a measurement unit with an 8-bit ADC (ADC2). Power management is supported by on-chip voltage regulators providing 5.0 V and 1.5 V supplies, ensuring operation within a single power supply range of 3.0 V to 27 V.

Feature Summary

• XC800 Core: 8-bit MCU compatible with 8051, supporting up to 40 MHz clock frequency with two clocks per machine cycle.
• Integrated Power Switches: Includes one High Side Switch (HS1) and two Low Side Switches (LS1, LS2) with PWM functionality.
• Communication Interfaces: Features a built-in LIN transceiver supporting LIN 1.3, 2.0, and 2.1 protocols, plus UART and SSC interfaces.
• Analog Capabilities: Equipped with an 8-channel 10-bit ADC (ADC1) and a measurement unit containing an 8-bit ADC (ADC2) with data post-processing.

Applications

• Automotive body electronics control modules
• LIN bus slave nodes in vehicle networks
• Relay driver applications requiring integrated switching
• LED lighting control systems

Procurement Notes

Verify the specific ordering suffix 'XUMA1' against Infineon's official documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the VQFN-48-22 package outline defined in the datasheet. Confirm that the component meets the required AEC-Q100 qualification standards for the intended automotive environment.

Selection Notes

Select this component when an 8051-compatible architecture with integrated power switches is required. The TLE9832 is suitable for applications needing LIN communication without external transceivers. Consider the 36 kByte Flash size and 256 Byte RAM capacity against application firmware requirements. Verify that the 10-bit ADC resolution and switch current capabilities meet the system's sensing and load-driving needs.

Part Context

The TLE9832 belongs to the TLE983x product family from Infineon Technologies, designed specifically for automotive embedded power applications. This series targets cost-effective solutions for body electronics by combining processing, communication, and power stages in a single chip. The QV variant utilizes a VQFN-48-22 package, distinguishing it from other pinout configurations within the same functional family.

Replacement Considerations

Consult Infineon's official cross-reference guides for verified replacements. Direct substitutes must maintain XC800 core compatibility, identical pinouts, and equivalent power switch ratings. Generic 8051 microcontrollers are not suitable replacements due to the lack of integrated automotive-grade power switches and LIN transceivers.
