This part is aimed at mixed-signal control applications — think motor drives, digital power conversion, and sensor fusion — where you need fast loop closure and a lot of analog inputs without adding external converters. The 100-TFBGA (8x8 mm) package keeps the footprint small, but the BGA pitch means the PCB layout needs careful fanout planning. ## Analog channel count and peripheral set With 42 analog inputs on the 12-bit ADC and 7 DAC outputs, this MCU can handle multi-phase current sensing, voltage monitoring, and waveform generation on a single chip. The connectivity list includes CANbus, I²C, SPI, QSPI, SAI, UART/USART, USB, and IrDA — enough for industrial fieldbus and sensor interfaces. ## Lifecycle and sourcing posture The base product number is STM32G473, so future die revisions or package variants will carry the same base.","metaTitle":"STM32G473VBH3 STM32G4 ARM Cortex-M4 MCU, 170 MHz","metaDescription":"STM32G473VBH3 32-bit MCU with ARM Cortex-M4 at 170 MHz, 128 KB Flash, 128K x 8 RAM, 42x12b ADC, 7x12b DAC, 100-TFBGA, -40 to 105°C.

At that speed the flash wait states need to be configured correctly in the clock tree — the datasheet's reference table gives the settings for zero-wait vs one-wait operation."},{"question":"How does STM32G473VBH3 compare to STM32G474?","answer":"The STM32G474 is a close sibling in the same G4 family. The main difference is that the G474 typically offers higher-resolution timers (HRTIM) for advanced power conversion, while the G473 focuses on the analog channel count. Both share the same 170 MHz Cortex-M4 core, 128 KB Flash option, and 100-TFBGA package — pin-compatible across the series, so a board swap is possible if the timer peripheral matches your need."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32G473VBH3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32G473VBH3 when reusing this data.
