170 MHz Cortex-M4F with FPU — real-time control loop headroom
The 11-channel 12-bit ADC and four 12-bit DAC channels reduce external analog front-end components in sensor and actuator designs.
Package and thermal management for space-constrained boards
Housed in a 32-UFQFN with exposed pad (5x5 mm body), the STM32G491KEU6 suits compact PCBs where board area is at a premium. Surface-mount assembly follows standard QFN reflow profiles; MSL rating should be verified from the latest STM datasheet revision before stencil design.
Peripheral set and connectivity for mixed-signal applications
The MCU integrates brown-out detect, POR, DMA, I²S, PWM, and a watchdog timer. Connectivity includes CANbus, I²C, IrDA, LINbus, SAI, SPI, UART/USART, and USB — enough to bridge fieldbus networks, sensor arrays, and human-machine interfaces without external protocol chips. The internal oscillator reduces external crystal count, though a precision external clock may be needed for USB or CAN timing compliance.
