TLE98432QXXUMA1

Overview

The TLE98432QXXUMA1 is an automotive-grade microcontroller from Infineon's TLE984x series, featuring an ARM Cortex-M0 core. It integrates a 52 kB Flash program memory and 4 kB RAM within a VQFN-48 package. The device supports a maximum clock frequency of 40 MHz and operates on a supply voltage range of 3 V to 28 V. Key peripherals include twelve ADC channels with 8-bit or 10-bit resolution, three timers/counters, and interfaces such as LIN, SSC, and UART. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +150°C.

Feature Summary

• ARM Cortex-M0 processor with 40 MHz max clock speed
• 52 kB Flash and 4 kB RAM memory configuration
• Twelve-channel ADC supporting 8-bit and 10-bit resolutions
• Integrated LIN, SSC, and UART communication interfaces

Applications

• Automotive body electronics control modules
• LIN bus node implementations in vehicle networks
• Sensor interface units requiring high-temperature operation

Procurement Notes

Verify the specific suffix characters replacing 'XX' in the part number to confirm exact memory variants and package options. Confirm AEC-Q100 qualification status for automotive deployment requirements. Check humidity sensitivity classification prior to surface mount assembly processes.

Selection Notes

Select this component when a 40 MHz Cortex-M0 solution with integrated power features is required. Ensure the 52 kB Flash capacity meets application code storage needs compared to the 48 kB variant in the TLE9843QX family. Verify that the VQFN-48 footprint aligns with PCB layout constraints.

Part Context

This unit belongs to the Infineon TLE984x family of embedded power microcontrollers designed for automotive environments. It shares architectural similarities with the TLE9843QX series but offers increased Flash memory and higher clock speeds. The QXX designation indicates specific internal configuration variations within the product line.

Replacement Considerations

The TLE9843QXXUMA1 serves as a higher-performance alternative to the TLE9843QXXUMA1, offering 52 kB Flash versus 48 kB and 40 MHz versus 25 MHz clock speeds. Both share the same VQFN-48 package and pinout compatibility.
