TLE9832QVXUMA2

Overview

The TLE9832QVXUMA2 is an automotive microcontroller featuring an XC800 core compatible with the standard 8051 architecture. It operates at a maximum clock frequency of 40 MHz and includes 36 kByte of Flash memory, 256 Byte RAM, and 3 kByte XRAM. The device integrates a LIN transceiver compliant with LIN 1.3/2.0/2.1 standards, one High Side Switch, and two Low Side Switches. Analog capabilities include an 8-channel 10-bit ADC (ADC1) and a measurement unit with an 8-bit ADC (ADC2). Power supply ranges from 3.0 V to 27 V, supporting operation within a junction temperature range of -40 °C to 150 °C in a VQFN-48 package.

Feature Summary

• XC800 8-bit MCU core with up to 40 MHz clock frequency
• Integrated LIN transceiver supporting LIN 1.3, 2.0, and 2.1 protocols
• Power switches: 1 High Side Switch and 2 Low Side Switches with PWM functionality
• On-chip memory: 36 kByte Flash, 256 Byte RAM, 3 kByte XRAM

Applications

• Automotive body electronics control units
• LIN bus node implementations
• Relay driver applications
• LED lighting control systems

Procurement Notes

Verify component authenticity through authorized Infineon distribution channels. Confirm package variant matches design requirements, as the TLE9832 family utilizes both VQFN-48-22 and VQFN-48-29 footprints. Ensure compliance with automotive environmental specifications for the intended operating temperature range.

Selection Notes

Select this model for applications requiring integrated power switching alongside an 8051-compatible instruction set. The presence of five High Voltage Monitor Inputs allows for direct battery monitoring without external attenuation circuits. Verify that the 36 kByte Flash capacity meets firmware storage needs before finalizing the selection.

Part Context

This component belongs to the TLE983x product family designed for cost-effective automotive solutions. It shares architectural similarities with other members like the TLE9834 but offers specific peripheral configurations including distinct memory sizes and switch counts tailored for body control modules.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the TLE9832QX variant, which shares identical electrical characteristics and memory size but differs in package outline (VQFN-48-29 vs VQFN-48-22). Cross-family migration requires schematic review due to differing peripheral sets.
