The 5-channel 10-bit sigma-delta ADC samples phase currents and rotor position at the PWM rate. The peripheral set includes a PWM unit with dead-time generation, a DMA controller for ADC-to-memory transfers without CPU intervention, and a watchdog timer for IEC 60730 safety compliance. Connectivity covers LIN 2.x for body-network bus communication and SPI for an external sensor hub. ## Supply and package — direct battery connection The 5.5 V to 27 V supply range lets the MCU connect directly to a 12 V automotive battery without a pre-regulator — the internal voltage regulator drops the rail to the core supply. The 10 GPIOs are enough for three hall-sensor inputs, a fault output, and a LIN transceiver enable — no port expansion needed for a basic brushless-DC pump or fan.","metaTitle":"Infineon TLE9879QTW40XUMA1 ARM Cortex-M3 MCU, 40 MHz","metaDescription":"Infineon TLE9879QTW40XUMA1 32-bit MCU, 128 KB flash, 6 KB RAM, 5.5-27 V supply, -40 to 175°C, AEC-Q100.
