What distinguishes this part from a plain Cortex-M4 is the analog peripheral set: 20 channels of 12-bit ADC and four 12-bit DAC channels, letting it sample multiple phase currents and output analog references without external converters. The connectivity block includes CANbus, I²C, SPI, QSPI, UART/USART, USB, and SAI for audio or serial-interface peripherals, making it a single-chip controller for inverter stages that also talk to a host or fieldbus. The 170 MHz core speed is the headline number that drives the control-loop budget. For a 20 kHz current-control loop with sensorless observer, each microsecond of margin matters — the 170 MHz clock gives roughly 170 instruction cycles per microsecond, enough to run a full FOC transform, PI regulators, and SVPWM update within a 50 µs PWM cycle. The Cortex-M4 FPU handles the trig and matrix math in hardware, so the firmware team does not need to hand-optimise fixed-point routines. If the application needs an OTA staging area, the 512 KB leaves room for a dual-bank scheme without external memory. ## 48-LQFP — pinout and board integration The 48-LQFP package with a 7x7 mm body exposes 38 I/O lines. That is enough for a three-phase inverter with Hall/encoder feedback, a CAN transceiver interface, a UART debug port, and a few spare GPIOs for fault indicators or auxiliary relays. The LQFP footprint is hand-solderable for prototypes and reflow-friendly for production. If the design needs 125°C junction capability, the STM32G4 family offers a 105°C variant in the same pinout; check the base number suffix. ## Active lifecycle — no near-term LTB risk STMicroelectronics lists the STM32G484CET6 as Active. There is no announced last-time-buy or end-of-life notice on this base product number. The STM32G4 series is a relatively recent addition to ST's portfolio, so roadmap support for new designs is solid — no need to qualify a second source for lifecycle reasons alone.","metaTitle":"STM32G484CET6 STMicroelectronics ARM Cortex-M4 MCU, 170MHz","metaDescription":"STM32G484CET6 32-bit MCU with ARM Cortex-M4 at 170MHz, 512KB Flash, 128KB SRAM, 48-LQFP.
