Product details
Overview
TLE9832QVXUMA1 from Infineon Technologies is an automotive-qualified 8-bit microcontroller integrating LIN transceiver, high-side and dual low-side power switches, 32 kB Flash + 4 kB emulated EEPROM, XC800 core (40 MHz), and on-chip 1.5 V/5.0 V regulators - designed for body control modules, seat/mirror actuators, and LIN-connected smart sensors in 12 V vehicle systems.
For engineers reviewing the TLE9832QVXUMA1 datasheet, TLE9832QVXUMA1 pinout, TLE9832QVXUMA1 application, or TLE9832QVXUMA1 equivalent, this device delivers integrated power switching, LIN physical layer compliance (LIN 1.3/2.0/2.1), real-time PWM generation via CCU6, and fail-safe clock monitoring - critical for cost-sensitive, space-constrained automotive subsystems requiring functional safety awareness.
Technical Context
The TLE9832QVXUMA1 implements a two-clocks-per-machine-cycle XC800 core derived from the 8051 architecture, with dedicated multiplication/division unit (MDU) and five 16-bit timers including Timer 12/13 within the Capture/Compare Unit 6 (CCU6) for precise motor control PWM. Its system clock derives from an internal oscillator with PLL multiplication and loss-of-clock detection triggering fail-safe shutdown of power switches.
Power management integrates three regulated supplies: 1.5 V core (VDDC), 5.0 V I/O (VDDP), and external 5.0 V support (VDDEXT), each with defined functional ranges and blocking capacitor requirements. The LIN transceiver meets ISO 17987-4 electrical specs and supports LIN Bootstrap Loader (LIN BSL) for in-vehicle firmware updates without external programming hardware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | XC800 (8051-compatible), 40 MHz max frequency - enables deterministic real-time control with 2-cycle instruction execution. |
| Memory | 32 kB Flash + 4 kB emulated EEPROM, 512 B OTP, 512 B 100TP, 256 B RAM, 3 kB XRAM - supports secure boot, field firmware updates, and parameter storage without external memory. |
| LIN Compliance | LIN 1.3 / 2.0 / 2.1 transceiver integrated - eliminates need for discrete LIN PHY, reduces BOM count and PCB area in node-level modules. |
| Power Switches | 1 high-side switch (1.2 A continuous, 2.5 A peak), 2 low-side switches (1.5 A each, clamped, PWM-capable) - drives relays, solenoids, and small motors directly from MCU pins. |
| Analog Peripherals | 10-bit ADC (8 channels), 8-bit ADC (2 channels), temperature sensor, VBAT sense attenuator - enables battery monitoring, thermal protection, and analog sensor interfacing without external signal conditioning. |
| Debug & Boot | 2-wire Device Access Port (DAP), LIN Bootstrap Loader (LIN BSL) - allows full debug access and firmware updates over existing LIN bus, eliminating dedicated debug headers. |
| Supply Regulation | On-chip 1.5 V (VDDC) core regulator and 5.0 V (VDDP) I/O regulator - simplifies power design by reducing external LDO count in 12 V automotive systems. |
Pinout & Package
Package: QFN-48 (7 mm × 7 mm, 0.5 mm pitch), thermally enhanced with exposed pad for improved heat dissipation in automotive under-hood environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP | I/O Supply Voltage | 5.0 V regulated supply input for GPIO, LIN transceiver, and digital peripherals - requires local 100 nF ceramic decoupling. |
| VDDC | Core Supply Voltage | 1.5 V regulated supply for XC800 core - generated internally from VDDP; bypassed externally with 10 µF tantalum + 100 nF ceramic. |
| HSW | High-Side Switch Output | Drives load between battery (VBAT) and HSW pin - supports 1.2 A continuous current with current-sense feedback for diagnostics. |
| LSW1, LSW2 | Low-Side Switch Outputs | Ground-switching outputs with active clamping and PWM capability - drive relays or lamps with built-in overcurrent protection. |
| LIN | LIN Bus Interface | Dedicated bidirectional LIN physical layer pin compliant to ISO 17987-4 - connects directly to LIN bus with no external transceiver required. |
| XTAL1/XTAL2 | Crystal Oscillator Inputs | Supports 1–20 MHz crystal for primary clock source; internal oscillator provides fallback if crystal fails. |
| ADCGND | Analog Ground Reference | Separate analog ground pin for ADC and measurement unit - must be connected to clean ground plane to ensure <±1 LSB ADC accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LIN Transceiver | Fully compliant with LIN 1.3/2.0/2.1 standards and ISO 17987-4, enabling direct connection to LIN bus without external PHY components. |
| Fail-Safe Clock Monitoring | Loss-of-clock detection triggers automatic shutdown of high/low-side switches - prevents uncontrolled actuator behavior during clock failure. |
| Embedded Power Switches | Single high-side (1.2 A) and dual low-side (1.5 A each) drivers with current sensing and PWM control reduce external MOSFETs and gate drivers. |
| LIN Bootstrap Loader (LIN BSL) | Enables firmware updates over LIN bus using standard LIN protocol frames - eliminates need for dedicated programming interface in production or service. |
| Thermally Optimized QFN-48 | Exposed pad package with RthJA = 40 K/W - sustains continuous operation at junction temperatures up to 150°C in engine bay applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive LIN-node microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLF35584ESV50 | Dedicated system basis chip (SBC) with LIN transceiver and watchdog - no MCU core or flash memory. | Requires external microcontroller; used where higher compute capability or larger memory is needed beyond TLE9832's scope. | Select when separating power management and computation improves functional safety partitioning (e.g., ASIL-D systems). |
| SPC560B50L5 | 32-bit Power Architecture MCU with CAN, no integrated LIN transceiver or power switches - requires external LIN PHY and drivers. | Targeted at higher-performance body domain controllers needing CAN connectivity and larger code footprint. | Choose when CAN bus integration and >128 kB Flash are mandatory, and BOM cost sensitivity is secondary to scalability. |
Compared with TLF35584ESV50 and SPC560B50L5, the TLE9832QVXUMA1 uniquely combines MCU, LIN PHY, and power switches in one QFN-48 package - delivering lowest component count and smallest PCB footprint for cost-driven LIN-actuated nodes below 40 MIPS compute demand.

FAQ
Does TLE9832QVXUMA1 support LIN 2.2 or later revisions?
No. The TLE9832QVXUMA1 implements LIN transceiver functionality compliant only with LIN 1.3, LIN 2.0, and LIN 2.1 specifications per its 2012 datasheet. It does not support LIN 2.2 or LIN 2.2a features such as configurable baud rate or enhanced checksum modes. For LIN 2.2+ compatibility, consider Infineon's newer TLE987x series.
What is the maximum ambient temperature rating for continuous operation?
The TLE9832QVXUMA1 is qualified for operation from −40 °C to +125 °C ambient temperature. Its thermal resistance (RthJA = 40 K/W) and exposed-pad QFN-48 package allow sustained 150 °C junction temperature under typical board layout conditions - meeting AEC-Q100 Grade 1 requirements for under-hood use.
Can the high-side switch be used in parallel with low-side switches for H-bridge motor control?
No. The TLE9832QVXUMA1 does not support simultaneous activation of HSW and LSW1/LSW2 in complementary mode for H-bridge operation. Its power switches are independently controlled and lack shoot-through protection logic. H-bridge control requires external half-bridge drivers or a dedicated motor control IC.
Is the 4 kB emulated EEPROM wear-leveled and certified for automotive endurance?
Yes. The 4 kB emulated EEPROM uses Infineon's proprietary wear-leveling algorithm across Flash sectors and is rated for ≥100,000 write cycles and 10-year data retention at 125 °C - validated per AEC-Q100 stress test conditions and documented in the TLE9832 qualification report.
