Product details

170 MHz Cortex-M4 in a 5x5 mm footprint

It integrates 11 analog-to-digital converters (12-bit) and 4 digital-to-analog converters (12-bit), plus a full set of connectivity: CANbus, I²C, IrDA, LINbus, SAI, SPI, UART/USART, and USB. 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.

Frequently asked questions

How does STM32G441KBU6 compare to STM32L151CBU6A?

The STM32L151CBU6A runs a Cortex-M3 at 32 MHz with 37 I/O and 2 DAC channels, versus the STM32G441KBU6's Cortex-M4 at 170 MHz with 26 I/O and 4 DAC channels. 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.
