That means a four-layer board with microvias or at least a tight via-in-pad layout is the practical minimum, not a luxury. That means ST continues to manufacture and support it for new designs. The STM32F103R8H6TR integrates a 16-channel 12-bit ADC, DMA controller, motor-control PWM, and a full set of watchdog timers. Connectivity includes CAN, USB, SPI, I²C, UART/USART, IrDA, and LINbus. ## Sourcing posture No stock or lead-time number can be stated here, but the active status means supply is not constrained by a phase-out — the part is still in regular production at ST.","metaTitle":"ST STM32F103R8H6TR ARM Cortex-M3 MCU, 72MHz, 64KB Flash","metaDescription":"STM32F103R8H6TR 32-bit ARM Cortex-M3 MCU from STMicroelectronics. 72MHz core, 64KB Flash, 20K x 8 RAM, 51 I/O.

A direct pin-compatible alternative would be any STM32F103RxH6 device (same package, same pinout) with a different Flash/RAM combination — for example, the STM32F103RBT6H6 with 128 KB Flash. The base product number STM32F103 covers the family; the exact peripheral set and memory map are verified against the target variant's datasheet."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F103R8H6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F103R8H6TR when reusing this data.
