GD32F303RCT6

GD32F303RCT6 is the LQFP-64 ordering code for the GigaDevice GD32F303 microcontroller, carried word-for-word in the maker’s 2025 selection guide: an Arm Cortex-M4 core at 120 MHz, 256 KB of Flash, 48 KB of SRAM and up to 51 GPIOs in the 64-pin package. GigaDevice publishes no per-code lifecycle grading in the captured material; the code stands in the maker’s current selection guide, and the status is stated in those neutral terms. The selection point is the 256 KB step of the GD32F303 line in the larger package: the same core and memory as the LQFP-48 family step carried on this site, with more pins brought out for designs that run out of I/O before they run out of compute. Selection advice: pin count is the difference here, not performance - confirm your pin multiplexing against the LQFP-64 assignment in the GigaDevice datasheet, and validate firmware on the GD32 device itself rather than assuming register-level identity with another vendor’s Cortex-M4 part. Parameters verified against the GigaDevice 2025 selection guide (GD32F303 line) and the GD32F30x family documentation.
