TLE9835QXXUMA1

Overview

The TLE9835QXXUMA1 is an automotive microcontroller from Infineon Technologies, featuring an XC800 core compatible with the standard 8051 architecture. It operates at a maximum clock frequency of 40 MHz and includes 64 kByte Flash memory. The device integrates two High Side Switches and two Low Side Switches for direct load driving. Communication is supported by a LIN transceiver compliant with LIN 2.1, alongside UART and SSC interfaces. Analog capabilities include an 8-channel 10-bit ADC (ADC1) and a 10-channel 8-bit ADC (ADC2). Power management features three internal voltage regulators (VDDP, VDDC, VDDEXT), allowing operation from a single supply between 3.0 V and 27 V.

Feature Summary

• XC800 8-bit MCU core with up to 40 MHz clock speed and 64 kByte Flash
• Integrated power stage with 2 High Side and 2 Low Side switches
• LIN 2.1 transceiver with full-duplex UART and synchronous serial channel
• Dual ADC system: 8-channel 10-bit and 10-channel 8-bit converters

Applications

• Automotive body electronics control modules
• LED lighting drivers and cyclic switch powering
• Relay driver applications via low-side outputs
• LIN bus slave nodes in vehicle networks

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product selection guide to confirm pin compatibility and memory configuration. Ensure the VQFN-48-29 package footprint matches the design layout. Confirm that the component meets the required AEC-Q100 qualification standards for the target automotive environment.

Selection Notes

Select this model when an integrated solution combining an 8051-compatible MCU with high-voltage power switches is required. The built-in LIN transceiver eliminates external components for network communication. Consider the 64 kByte Flash capacity for application firmware size and verify that the 27 V maximum supply voltage aligns with the vehicle's electrical system specifications.

Part Context

This component belongs to the TLE983x family of automotive microcontrollers designed for cost-effective solutions in body electronics. It shares the XC800 core architecture with other devices in the series but offers a specific peripheral configuration including dual power switches and extensive analog monitoring inputs suitable for sensor interfacing.

Replacement Considerations

Consult the official Infineon cross-reference documentation for verified alternative part numbers within the TLE983x or TLE984x families. Ensure any substitute maintains identical pinout, memory size, and power switch ratings to guarantee mechanical and functional interchangeability.
