On-chip memory pairs 512 KB of flash with 128 KB of SRAM; the flash uses a 4-way set-associative prefetch buffer to keep the core fed at full clock speed without wait-state penalties on sequential code. The 42-channel 12-bit ADC bank samples simultaneously across up to three converters — useful for reading three-phase motor currents plus a DC-link voltage in one conversion cycle. The four 12-bit DAC channels output analog setpoints or reference voltages without external converters. ## Peripheral mix and connectivity for fieldbus and instrumentation Connectivity includes CANbus (two FD-capable controllers), QSPI for external flash or RAM expansion, SAI for digital audio, and a full-speed USB device/host/OTG interface — enough to build a CANopen fieldbus node that logs data to an external NOR flash and streams it over USB. The 107 general-purpose I/O pins are multiplexed across the 128-LQFP package; most are 5 V-tolerant, so level translation is optional when interfacing to legacy 5 V logic or sensor rails. On-chip brown-out detect, power-on reset, and a windowed watchdog reduce the external supervisor count to zero for most designs — the BOR threshold is programmable from the flash option bytes. The package ships in a tray — no reel or tape; plan for a tray feeder or manual placement in the pick-and-place setup.","metaTitle":"STM32G484QET6 STM32G4 MCU, 170 MHz Cortex-M4, 512 KB Flash","metaDescription":"STM32G484QET6 ARM Cortex-M4 MCU, 170 MHz, 512 KB flash, 128 KB SRAM, 42-ch ADC, 4-ch DAC, CANbus, QSPI, USB.
