TLE9832QXXUMA2

Overview

The TLE9832QXXUMA2 is an automotive microcontroller featuring an XC800 core compatible with the standard 8051 architecture, operating at up to 40 MHz. It integrates 36 kByte of Flash memory (including 4 kByte EEPROM emulation), 256 Byte RAM, and 3 kByte XRAM. The device includes a LIN transceiver compliant with LIN 1.3/2.0/2.1 standards, one High Side Switch, two Low Side Switches, and five High Voltage Monitor Inputs. Analog capabilities consist of an 8-channel 10-bit ADC and an 8-bit ADC within the measurement unit. Power management features include on-chip 5.0V and 1.5V regulators, supporting a single supply voltage range from 3.0 V to 27 V.

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
• Embedded power switches: 1 High Side and 2 Low Side outputs
• On-chip analog peripherals including 8-channel 10-bit ADC and 5 HV monitor inputs

Applications

• Automotive body electronics control units
• LIN bus slave nodes in vehicle networks
• Relay driver applications utilizing low side switch PWM functionality
• LED driving circuits powered by the high side switch

Procurement Notes

Verify component authenticity through authorized Infineon distribution channels. Confirm package variant compatibility, as the TLE9832 family utilizes VQFN-48-22 or VQFN-48-29 footprints. Ensure design adherence to the specified 3.0 V to 27 V supply range and -40 °C to 150 °C junction temperature limits for automotive reliability.

Selection Notes

Select this model for applications requiring integrated LIN communication and embedded power switching without external drivers. The 36 kByte Flash capacity supports moderate firmware complexity. Verify that the 11 bidirectional GPIO pins and specific peripheral assignments (CCU6, Timers) align with the target hardware interface requirements.

Part Context

This component belongs to the TLE983x product family, designed specifically for cost-effective automotive solutions. It shares the XC800 core architecture with other devices in the series but offers a distinct configuration of memory sizes and peripheral modules tailored for body control and sensor interfacing tasks.

Replacement Considerations

Direct replacements within the same family include the TLE9832QV and TLE9832QX variants, which share identical electrical specifications and pinouts but differ in package dimensions (VQFN-48-22 vs. VQFN-48-29). Cross-family migration requires re-evaluation of software libraries and peripheral configurations.
