It packs 16 KB of Flash and 6K x 8 of SRAM — enough for a single control loop or a sensor-fusion task, but tight for a full protocol stack. The 64-TFBGA (5x5 mm) footprint squeezes 51 I/O into a BGA that demands a multi-layer PCB and careful routing. Peripheral set includes CAN, USB, SPI, I²C, and motor-control PWM with a dedicated DMA engine, making it a fit for compact drives, industrial I/O nodes, or CAN-bus gateways where board space is the constraint. The STM32F103R4H6A carries an EOL hot lifecycle status. For existing designs, we source this part through independent distribution against an RFQ. Suitable for factory automation, outdoor telecom enclosures, and engine-bay-adjacent electronics where the ambient stays below 85°C. Not qualified to AEC-Q100, so avoid automotive safety-critical paths without additional qualification data.","metaTitle":"ST STM32F103R4H6A ARM Cortex-M3 MCU, 72 MHz, 16 KB Flash","metaDescription":"STM32F103R4H6A 32-bit MCU with 72 MHz Cortex-M3 core, 16 KB Flash, 6K x 8 RAM, CAN/USB/SPI, 51 I/O in 64-TFBGA.
