STS3C2F100

Overview

The STM32F100C2T6 is a mainstream value line microcontroller from STMicroelectronics, based on the Arm Cortex-M3 core. It features 128 Kbytes of Flash memory and 16 Kbytes of SRAM. The device operates at a maximum frequency of 24 MHz and supports a supply voltage range of 2.0 V to 3.6 V. It includes standard communication interfaces such as I2C, SPI, USART, and UART, along with timers, ADCs, and DACs. Designed for cost-sensitive applications, it offers motor control capabilities and HDMI CEC functions within a compact LQFP-48 package.

Feature Summary

• Arm Cortex-M3 32-bit RISC core with single-cycle multiplication
• Integrated flexible static memory controller for external memory access
• Comprehensive set of power-saving modes for low-power designs
• Extensive peripheral range including multiple communication interfaces

Applications

• Motor drives and industrial control systems
• Medical equipment and handheld devices
• PC peripherals and gaming accessories
• GPS platforms and PLCs
• HVAC systems and alarm systems

Procurement Notes

Verify the specific suffix (e.g., T6 for tape and reel) against the required packaging format. Confirm the temperature grade matches the application environment, as the F100 family spans commercial and extended ranges. Ensure the pin count and package type align with the PCB layout requirements before finalizing the order.

Selection Notes

Select this model when 128 KB of Flash and 16 KB of RAM are sufficient for the application logic. It is suitable for designs requiring the Cortex-M3 architecture but needing fewer resources than high-density variants. Consider the 24 MHz speed limit and available GPIO count to ensure compatibility with system performance needs.

Part Context

This component belongs to the STM32F100xx Value Line family, which targets cost-effective embedded applications. It shares the same Cortex-M3 core as higher-end models but reduces memory size and peripheral counts to lower the overall bill of materials. It serves as an entry point into the STM32 ecosystem for basic control tasks.

Replacement Considerations

Direct replacements include other STM32F100xC devices with different memory sizes or packages, such as STM32F100C4T6 or STM32F100CBT6. Cross-family migration to STM32G0 or STM32L0 series may require software adaptation due to architectural differences.
