170 MHz Cortex-M4 with analog-rich peripheral set
The STM32G441RBT6 is a 32-bit ARM Cortex-M4 MCU from STMicroelectronics, clocked at 170 MHz, with 128 KB Flash and 32K x 8 RAM. It integrates a 23-channel 12-bit ADC and four 12-bit DACs, making it a fit for mixed-signal control loops in motor drives, digital power supplies, and industrial sensors. The -40°C to 85°C operating range suits factory-floor and outdoor telecom enclosures.
Lifecycle and sourcing reality
Peripheral set and connectivity
On-chip peripherals include brown-out detect, reset, DMA, I²S, POR, PWM, and watchdog timer. Connectivity covers CANbus, I²C, IrDA, LINbus, SAI, SPI, UART/USART, and USB. With 52 I/Os in a 64-LQFP package, the device can handle multiple serial buses alongside analog inputs and PWM outputs without external muxing.
