The part is aimed at applications that need a single-chip controller with substantial code space and a rich peripheral set: motor drives using the dedicated PWM timers, industrial fieldbus nodes with CAN and multiple UARTs, and human-machine interfaces with USB connectivity. ## Peripheral set and I/O — what fits on 51 pins With 51 general-purpose I/O lines, the STM32F103RGT7 balances pin count against peripheral multiplexing. The connectivity block covers CANbus, I²C, SPI, USART/UART, IrDA, LINbus, and USB — a typical industrial control node can handle a CANopen fieldbus, a UART for a display panel, and an I²C temperature sensor all on one die. DMA offloads the CPU for peripheral-to-memory transfers, and the motor-control PWM timers support six-step commutation for three-phase BLDC drives. ## Package and footprint — 64-LQFP, 10x10 mm, 0.5 mm pitch ## Lifecycle — active, no end-of-life signal ST continues to manufacture the STM32F1 series, and there is no published last-time-buy or obsolescence notice for this specific order code. The STM32F103RGT7 is a mainstream volume part with broad distribution coverage. Lead times have normalized from the 2021–2023 allocation period, and franchised distributors carry stock at the factory and regional hubs. Independent distribution also holds excess from over-ordered programs, so spot pricing is competitive for small-lot fills. The part is ROHS3 compliant. For a production BOM line, dual-sourcing through a franchised line card plus an independent channel is feasible — the part is not single-source constrained.","metaTitle":"STM32F103RGT7 STM32F1 ARM Cortex-M3 MCU, 72 MHz, 1 MB Flash","metaDescription":"STM32F103RGT7 32-bit MCU with 72 MHz ARM Cortex-M3 core, 1 MB Flash, 96 KB RAM, 51 I/O, CAN/USB, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":"STM32F1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F1","Package":"Tray","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, Motor Control PWM, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"51","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F103","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.9400","priceTiers":[{"qty":1,"price":"$12.94000","currency":"USD"},{"qty":10,"price":"$11.89000","currency":"USD"},{"qty":25,"price":"$11.39720","currency":"USD"},{"qty":160,"price":"$10.04175","currency":"USD"},{"qty":320,"price":"$9.54894","currency":"USD"},{"qty":480,"price":"$8.93285","currency":"USD"},{"qty":960,"price":"$8.19359","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1e0a2899638e8adeb34943c703bd9a9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103RGT7/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum operating frequency of STM32F103RGT7?","answer":"The core runs at 72 MHz, the maximum clock speed for the STM32F103 family.
