It packs 51 GPIOs, a motor-control PWM timer, CANbus, USB, and dual 12-bit DACs into a 64-LQFP package. Typical applications include industrial drives, motor-control boards, and embedded control nodes that need a single 2 V to 3.6 V supply and operate from -40 °C to 85 °C. ## 256 KB Flash and 48 KB RAM — what the memory map buys you 256 KB of Flash and 48 KB of RAM support a moderate application firmware, bootloader, and small file system. ## EOL status — sourcing reality for this order code The STM32F103RCT6TR is recorded as end-of-life (EOL). Factory orders are no longer accepted; supply is through independent-distribution surplus and broker channels. ## Peripheral set and deployment context The motor-control PWM timer, CANbus interface, and dual 12-bit DACs target industrial motor-drive and control applications. The 51 GPIOs in a 64-LQFP give enough headroom for a keypad, a small character display, and a few encoder inputs. The internal oscillator and POR/PVD reduce external BOM count on a two-layer board.","metaTitle":"ST STM32F103RCT6TR ARM Cortex-M3 MCU, 72 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32F103RCT6TR 32-bit MCU, 72 MHz Cortex-M3, 256 KB Flash, 48 KB RAM, 64-LQFP.
