On-chip memory is 128 KB of flash and 128 KB of SRAM (128K x 8) — enough for a real-time operating system, a communication stack, and a moderate application buffer without external memory. The flash is single-bank, so simultaneous read-while-write is not supported; plan firmware updates around a bootloader in the first sector. ## Analog integration and connectivity The ADC subsystem provides 26 channels of 12-bit resolution, and the DAC offers 4 channels at 12 bits. For a three-phase current-sense application, the 26-channel count leaves headroom for voltage and temperature monitoring on the same die — no external multiplexer needed. The QSPI interface can drive an external serial flash for data logging without bit-banging. ## Package and board integration 52 GPIOs are available in the 64-pin package — a high pin-to-package ratio that suits mixed I/O designs where you need parallel data buses alongside analog inputs.","metaTitle":"STM32G473RBT6 STM32G4 MCU, 170 MHz Cortex-M4, 128 KB Flash","metaDescription":"STM32G473RBT6: ARM Cortex-M4 at 170 MHz, 128 KB flash, 128 KB SRAM, 26x12-bit ADC, 4x12-bit DAC.
