TLE98442QXXUMA1

Overview

The TLE98442QXXUMA1 is a 32-bit embedded power system-on-chip (SoC) from Infineon's MOTIX™ family, designed for automotive applications. It integrates an Arm® Cortex®-M0 microcontroller with high-side and low-side switches, relay drivers, and a LIN transceiver. The device operates on a supply voltage range of 5.5 V to 28 V and features 64 kByte of flash memory, 4 kByte of RAM, and 18 GPIOs. It supports a system clock frequency up to 40 MHz and includes interfaces such as PWM and LIN. The component is housed in a PG-VQFN-48 package and is qualified for automotive use within a temperature range of -40 °C to 150 °C.

Procurement Notes

Verify the specific ordering suffix 'UMA1' against the manufacturer's current datasheet to confirm pinout and functional compatibility. Ensure the procurement channel provides original packaging documentation to validate authenticity. Check for any recent errata sheets related to the TLE984xQX family before finalizing orders.

Selection Notes

Select this model when a complete SoC solution is required for motor control or relay switching in automotive environments. It is suitable for designs needing integrated power management and LIN communication without external discrete components. Compare flash and RAM requirements against other variants in the TLE984x series if cost optimization is necessary.

Part Context

This part belongs to the MOTIX™ motor control SoCs family, specifically the TLE984xQX series. It shares architectural similarities with the TLE9844-2QX and TLE9842QX but offers distinct memory configurations. The TLE98442QXXUMA1 represents a specific tape-and-reel variant of the TLE98442QXX chip, optimized for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes within the same package include the TLE98442QXXUMA2. For pin-compatible alternatives with different memory sizes, consider the TLE9844QX or TLE9842QX, provided software adaptation is feasible.
