That ADC count covers multi-phase current sensing in a three-phase motor drive plus a spare for a thermistor or DC-link voltage. The four DACs can generate independent reference or offset voltages, or drive analog set-points without external converters. For a mixed-signal control loop — digital power, field-oriented motor control, or sensor conditioning — this peripheral set reduces external component count and board area. ## Connectivity and debug in a 48-pin LQFP The CAN and LIN support is useful for automotive or industrial bus nodes. For debug and programming, the part works with ST-Link and J-Link probes over the standard SWD interface — no special adapter needed. ## Active lifecycle and tape-and-reel ordering The base part STM32G431CBT6 is the same silicon in a tray or tube; the only difference is the shipping medium. For a production BOM, the TR variant is the one that feeds the line directly.","metaTitle":"STM32G431CBT6TR, 32-bit ARM Cortex-M4 MCU, 170 MHz","metaDescription":"STMicroelectronics STM32G431CBT6TR: 32-bit ARM Cortex-M4 MCU at 170 MHz, 128 KB Flash, 32 KB SRAM, 17x12b ADC, 4x12b DAC, 48-LQFP.
