Ordering Code Difference
STM32F103C6T6ATR vs STM32F103C8T6TR: What Is the Difference?
STM32F103C8T6 and STM32F103C8T6TR are functionally equivalent STMicroelectronics STM32F103 32-bit Arm Cortex-M3 microcontrollers with 72MHz performance, 64KB Flash, 20KB SRAM, USB, CAN, ADCs, timers and serial communication interfaces in a 48-pin LQFP package. The main difference is the ordering and packaging format: STM32F103C8T6 is commonly used as the standard part number, while STM32F103C8T6TR specifies tape-and-reel packaging for SMT production.

STM32F103C8T6TR | Tape-and-reel version of STM32F103C8T6, intended for automated SMT assembly. Electrical specifications, pinout, package and MCU functions are the same as STM32F103C8T6. | Can usually replace STM32F103C8T6 when the same MCU specification is required and the only difference is packaging format. Confirm reel, cut-tape or tray supply before production purchase. |
STM32F103C8T6 and STM32F103C8T6TR are the same STM32F103C8 MCU specification, but they may be supplied in different packaging formats. STM32F103C8T6 is commonly used for tray or general distributor stock, while STM32F103C8T6TR indicates tape-and-reel packaging for automated SMT assembly. For prototyping, repair, or small-volume orders, confirm whether the stock is tray, cut tape, or reel. For mass production, STM32F103C8T6TR is usually preferred because tape-and-reel packaging is compatible with pick-and-place machines. Always verify the original manufacturer, lot/date code, package condition, RoHS status, and whether the device marking matches STMicroelectronics material before purchasing.

STM32F103C8T6 is a 48-pin, 64 KB Flash option in the STM32F103 performance line and is suitable for compact embedded designs that need Cortex-M3 performance, USB, CAN and common serial interfaces. STM32F103CBT6 is the closest upgrade when more Flash memory is required while keeping a similar 48-pin package. STM32F103C6T6 is a lower-memory alternative for simpler firmware. STM32F103R8T6 provides more pins in a 64-pin package while staying in the 64 KB Flash class. STM32F103RCT6 is a higher-density option with 256 KB Flash and more I/O resources, making it better suited for larger applications or designs with heavier peripheral requirements.
