Applications
STM32F103C8T6 is a 32-bit Arm Cortex-M3 MCU widely used in industrial control, USB dongles, motor drivers, and the “Blue Pill” prototype boards. Confirm Flash (64 KB), SRAM, and LQFP-48 pinout before swapping nearby F103 suffixes.
Procurement notes
During ST shortages, check date-code, original vs pulled stock, and whether your firmware needs the on-chip USB bootloader. SJ Chip lists live STM32F103C8T6 inventory; send an RFQ for reel/tray quantities and lead time. Review the datasheet and pinout before using F103CBT6 or GD32F103C8T6 as an evaluation alternate.

FAQ
Is STM32F103C8T6 currently available?
Availability is shown on this product page from live inventory and changes as lots move. Submit an RFQ with quantity and required date so SJ Chip can confirm remaining stock, date code, and lead time before you issue a PO.
Can STM32F103C8T6 be replaced by GD32F103C8T6?
GD32F103C8T6 may be a potential alternative / requires engineering validation (pinout, firmware, clocks, power, and errata). It is not a direct replacement. Do not change the AVL until the customer's engineering team approves the evaluation.
Is this a drop-in replacement?
No. SJ Chip does not list parts as drop-in or direct replacements. Any nearby MPN is a potential alternative / requires engineering validation before production use.
How can I request a quotation?
Open https://www.sj-chip.com/rfq, enter the full part number, quantity, and required date. The sourcing team replies within 24 working hours with availability, condition, and lead time on the quotation.
Is STM32F103C8T6 pin-compatible with STM32F103CBT6?
Same LQFP-48 footprint in most designs, but Flash size and some peripheral options differ. Always compare the ST datasheet and your linker/memory map before substituting.
Can I use GigaDevice GD32F103C8T6 as an alternate?
Many boards boot GD32F103 in place of STM32F103, but clocks, USB, and errata are not identical. GD32F103C8T6 is a potential alternative / requires engineering validation — not a drop-in or direct replacement.
