Infineon Technologies TLE9877QXA20XUMA2

Overview

TLE9877QXA20XUMA2 from Infineon is a 32-bit automotive-grade microcontroller integrating Arm® Cortex®-M3 core, 64 KB flash, 6 KB RAM, LIN 2.2 transceiver, and integrated BLDC MOSFET driver with charge pump. It operates from 5.5 V to 27 V supply and supports junction temperature up to +150°C, targeting motor control in wiper, fan, and window lift systems.

For engineers reviewing the TLE9877QXA20XUMA2 datasheet, TLE9877QXA20XUMA2 pinout, TLE9877QXA20XUMA2 application, or TLE9877QXA20XUMA2 equivalent, key selection criteria include single-supply operation, on-chip clock generation (OSC + PLL), high-speed op-amp for shunt-based current sensing, AEC-Q100 qualification, and VQFN-48 package thermal performance.

Technical Context

The TLE9877QXA20XUMA2 implements a tightly coupled system-on-chip architecture where the Cortex-M3 core executes motor control algorithms while dedicated hardware modules handle real-time tasks: CCU6 provides six-channel PWM with dead-time insertion for BLDC commutation, GPT12 timers support precise timing for sensorless FOC, and the integrated LIN transceiver enables direct communication with body control modules without external level-shifting.

Its power management unit integrates three regulated supplies: 5.0 V (VDDP) for digital logic, 1.5 V (VDDC) for core voltage, and an external 5.0 V regulator interface (VDDEXT) for peripheral rail flexibility. The on-die high-precision oscillator (OSC_HP) supports both crystal and external clock input modes, enabling ±1% frequency stability over temperature for timing-critical motor control loops.

FAQ

What is the maximum operating frequency of the Cortex-M3 core in the TLE9877QXA20XUMA2?

The Arm Cortex-M3 core operates at up to 40 MHz, derived from the on-chip PLL locked to either the internal oscillator or external crystal. This frequency is fixed in hardware and cannot be overclocked; it provides deterministic timing for motor control loops with worst-case interrupt latency under 12 cycles.

Does the TLE9877QXA20XUMA2 support sensorless BLDC commutation out of the box?

Yes - the device includes dedicated hardware blocks (CCU6, GPT12, and ADC with fast conversion mode) that enable sensorless commutation using back-EMF zero-crossing detection. Reference firmware examples for trapezoidal and FOC control are provided in Infineon's AURIX™ and TLE987x SDKs.

Can the integrated LIN transceiver interface directly with a 12 V automotive battery without level shifting?

No - the LIN transceiver operates from the internal 5.0 V VDDP rail and interfaces directly with the LIN bus via TXD_LIN/RXD_LIN pins. It meets ISO 17987-4 physical layer requirements and includes bus fault protection up to ±40 V, eliminating need for external level shifters or protection diodes.

Is the VQFN-48-31 package RoHS and REACH compliant?

Yes - the TLE9877QXA20XUMA2 uses a lead-free, halogen-free VQFN-48-31 package qualified to JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and fully compliant with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006.
