The 26-channel 12-bit ADC and 7-channel 12-bit DAC let it handle simultaneous current/voltage sensing and analog output in a single chip, which is the main draw over general-purpose MCUs in this footprint. ## Mixed-signal density: 26 ADC channels, 7 DAC channels The STM32G474RET6 carries 26 analog-to-digital converter channels (12-bit) and 7 digital-to-analog converter channels (12-bit) — a density unusual in a 64-pin LQFP. For a three-phase motor drive, you can sample all phase currents plus the DC-link voltage on dedicated ADC channels while the DACs generate reference voltages or analog setpoints. The date-code and marking consistency should trace cleanly back to ST's authorized chain — the laser etch on the 64-LQFP body is a straightforward authenticity check for incoming inspection.","metaTitle":"STM32G474RET6 ARM Cortex-M4F MCU, 170 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32G474RET6 32-bit MCU with 170 MHz Cortex-M4F, 512 KB Flash, 128 KB SRAM, 26x12b ADC, 7x12b DAC, CAN, QSPI, -40 to 85°C.

Both run at 170 MHz, share the same 64-LQFP package, peripheral set, and 128 KB SRAM. The RET6 is the higher-density option for firmware that exceeds the 256 KB threshold."},{"question":"Is there a replacement or equivalent for the STM32G474RET6?","answer":"The STM32G474RET6 is an active part with no official replacement. Within the STM32G4 family, the STM32G474RCT6 (256 KB Flash) is a lower-density alternative with the same package and pinout. The STM32L151CBU6A is a different-series MCU (Cortex-M3, 32 MHz, lower power) and is not a functional second-source — it lacks the 170 MHz performance and the 26-channel ADC / 7-channel DAC density of the G474."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32G474RET6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32G474RET6 when reusing this data.
