The 24 MHz Cortex-M3 handles moderate-speed control loops and sensor polling. The 24K x 8 RAM limits firmware complexity.
The 256 KB Flash fits a bootloader and protocol stack. The 24K x 8 SRAM is adequate for moderate data buffering.
STMicroelectronics has marked the STM32F100RCT6TR as NRND.
ST does not list a single pin-compatible direct replacement for the STM32F100RCT6TR. For new designs, ST recommends migrating to the STM32F0 or STM32G0 series (Cortex-M0+) or the STM32F3 series (Cortex-M4) for a feature upgrade. For existing BOMs, the STM32F100RBT6 (128 KB Flash) is pin-compatible if the Flash budget allows.
The STM32F100RCT6TR is supplied in a 64-pin LQFP package (10 mm x 10 mm body, 0.5 mm pitch). It is a surface-mount device.
The STM32F100RCT6TR is the Tape & Reel (TR) packaging variant of the base STM32F100RCT6. The silicon is identical; the only difference is the shipping format (Tape & Reel vs. tray or tube). They are functionally and pin-compatible.
The STM32F100RCT6TR is rated for -40°C to 85°C ambient operating temperature, making it suitable for industrial environments.
