The 32-UFQFPN package with exposed pad (5x5 mm) suits space-constrained, mixed-signal control applications like motor drives, digital power conversion, and industrial sensors. ## What the 170 MHz and memory mean for your BOM If your algorithm needs more data memory, you will be looking at the larger RAM variants in the STM32G4 family. The 26 I/O lines include the analog inputs and DAC outputs, so plan the pin allocation early if you need all 11 ADC channels simultaneously.","metaTitle":"STM32G441KBU6 ARM Cortex-M4 MCU, 170MHz, 128KB Flash","metaDescription":"STMicroelectronics STM32G441KBU6 32-bit ARM Cortex-M4 MCU at 170MHz with 128KB Flash, 32K x 8 RAM, 11x12b ADC, 4x12b DAC.

The G4 part delivers over 5x the clock speed and more analog output channels, but the offers lower power and more I/O in a similar package. They are not pin-compatible; the choice depends on whether you need the M4 DSP/FPU throughput or the ultra-low-power profile."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32G441KBU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32G441KBU6 when reusing this data.
