| Parameter | STM32F103RCT6 | APM32F103RCT6 | Engineering note |
|---|---|---|---|
| Package and complete pin sequence | STM32F103RCT6: LQFP64, 10 x 10 mm | APM32F103RCT6: LQFP64, 10 x 10 mm, tray SPQ 1600 | The exact order codes are both LQFP64. Table-based comparison confirmed identical main-function names on pins 1 through 64. PCB land-pattern, assembly, reel/tray handling and thermal design still require independent release checks. |
| SRAM | 48 KB | 64 KB | The target provides 16 KB more SRAM. Firmware memory maps, linker scripts, stack/heap placement and RAM initialization must be rebuilt for the target. |
| Maximum core frequency | 72 MHz | 96 MHz | The target has more clock headroom. Recalculate clocks, bus dividers, peripheral timing and Flash access timing before using a clock above the source design limit. |
| Operating supply and temperature | 2.0 V to 3.6 V; suffix 6 rated -40 C to +85 C | 2.0 V to 3.6 V; APM32F103RCT6 order table rated -40 C to +85 C | The reviewed exact-code supply and ambient ranges match. Do not substitute wider series-page temperature options into this exact order code. |
| Registers, peripherals and software | STM32F103 peripheral identifiers, registers, clock tree and firmware ecosystem | Geehy APM32F103 peripheral identifiers, registers, clock tree and firmware ecosystem | The physical main-function pin sequence corresponds, but a firmware port, startup code, clock configuration, driver review and peripheral validation are still required. |
FAE documentary review accepted for the exact STM32F103RCT6 and APM32F103RCT6 order codes. Both are 256 KB Flash, 51-GPIO, 2.0 V to 3.6 V LQFP64 Cortex-M3 MCUs, and the complete 64-pin main-function sequence matches. The target increases SRAM from 48 KB to 64 KB and maximum core frequency from 72 MHz to 96 MHz. The exact RCT6 order table confirms -40 C to +85 C. Pin correspondence does not establish register, clock, ADC, driver or software compatibility. Document review only; not bench, temperature-cycle, EMC, reliability or production qualified.
