The 42-channel 12-bit ADC array lets you sample all three phase currents plus the DC link in a single trigger event, and the seven 12-bit DAC channels can spit out analog set points or offset trim voltages without external converters. ## I/O and connectivity — 107 pins, CAN, QSPI With 107 I/O lines in a 128-LQFP package, this MCU can talk to a lot of the outside world directly — parallel LCDs, encoder interfaces, multiple UARTs for daisy-chained drives. The connectivity set includes CANbus, I²C, SPI, QSPI, UART/USART, IrDA, and LINbus, which covers industrial fieldbus bridging and sensor aggregation without extra transceivers on the same die. The QSPI interface is handy for memory-mapped external Flash or PSRAM if the 128 KB internal RAM runs short for a frame buffer or data logger. It is a current-production part in the STM32G4 series, so there is no end-of-life clock ticking on new designs.","metaTitle":"STM32G474QET6 ARM Cortex-M4F MCU, 170 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32G474QET6 32-bit MCU with ARM Cortex-M4F at 170 MHz, 512 KB Flash, 128 KB RAM, 42-ch 12-bit ADC, 128-LQFP.
