TLE9834QXXUMA2

Overview

The TLE9834QXXUMA2 is an automotive microcontroller from Infineon Technologies, part of the TLE983x family. It integrates a high-performance XC800 core compatible with the standard 8051 architecture, operating at clock frequencies up to 40 MHz. The device features 64 kByte of Flash memory for program code and data, complemented by 256 Byte RAM and 3 kByte XRAM. Key peripherals include a LIN transceiver compliant with LIN 1.3/2.0/2.1 standards, two High Side Switches, two Low Side Switches, and five High Voltage Monitor Inputs. Analog capabilities are provided by an 8-channel 10-bit ADC (ADC1) and an 8-bit ADC (ADC2). The component operates on a single power supply ranging from 3.0 V to 27 V and is housed in a VQFN-48-29 package.

• LED driving and powering of switches

Procurement Notes

The TLE9834QXXUMA2 is listed as an End-of-Life (EOL) product by Infineon Technologies. Verification of current availability requires consulting official distributor channels or contacting the manufacturer directly, as stock status may vary. Designers should review the EOL notification documents for transition timelines and recommended replacement strategies.

Selection Notes

Select the TLE9834QXXUMA2 for automotive applications requiring integrated power switching and LIN communication. Ensure the design accommodates the VQFN-48-29 package thermal requirements. Verify that the 64 kByte Flash capacity meets firmware needs, as this variant lacks an operational amplifier found in other family members. Confirm compatibility with the 3.0 V to 27 V supply range and -40 °C to 150 °C junction temperature operation.

Part Context

This component belongs to the TLE983x series of embedded power microcontrollers designed specifically for automotive environments. It shares the XC800 core architecture with other devices in the MOTIX™ portfolio but is distinguished by its specific peripheral configuration, including the exact count of flash memory, switches, and monitor inputs defined for the TLE9834QX variant.

Replacement Considerations

As an EOL product, verify if newer revisions within the TLE983x family or alternative Infineon motor control SoCs like the TLE98xx series are suitable replacements. Check pinout compatibility and software library support before transitioning designs to substitute components.
