TLE98322QXXUMA1

Overview

The TLE9832-2 is an automotive microcontroller integrating an XC800 core with a LIN transceiver and power switches. It features a single supply voltage range of 3.0 V to 27 V, supporting up to 40 MHz clock frequency. The device includes 36 kByte Flash memory, 256 Byte RAM, and 3 kByte XRAM. Peripheral modules consist of two High Side Switches, two Low Side Switches, five High Voltage Monitor Inputs, an 8-channel 10-Bit ADC, and an 8-bit ADC. It operates within a junction temperature range of -40 °C to 150 °C.

Feature Summary

• XC800 Core: 8-bit architecture compatible with standard 8051, operating at up to 40 MHz with two clocks per machine cycle.
• Integrated Power Stage: Includes two High Side Switches with cyclic sense and two Low Side Switches with clamping capability.
• Communication Interface: Built-in LIN transceiver compliant with LIN 1.3, 2.0, and 2.1 standards alongside UART and SSC.
• Measurement Unit: Features an 8-channel 10-Bit ADC (ADC1) and an 8-bit ADC (ADC2) for battery and supply monitoring.

Applications

• Body electronics control units
• LIN bus node implementations
• LED driving applications
• Relay driver circuits

Procurement Notes

Verify the specific suffix (e.g., QV or QX) against the required package type, as the TLE9832-2 family utilizes VQFN-48-22 and VQFN-48-29 packages. Confirm RoHS compliance status through official Infineon documentation prior to integration.

Selection Notes

Select based on the required I/O count and memory size; both QV and QX variants offer identical 36 kByte Flash and peripheral configurations. Ensure the application voltage stays within the 3.0 V to 27 V functional range and consider the thermal resistance characteristics for the chosen package.

Part Context

This component belongs to the TLE983x product family designed for cost-effective automotive solutions. It integrates the MCU, power management, and communication interfaces into a single chip to reduce external component count and simplify circuit design.
