Note: This product is non-returnable.

The STM32F103C8T6 Microcontroller with LQFP48 Package is one of the most advanced and widely used ICs in the STM32 family, designed for industrial projects and embedded systems. This STM32F103C8T6 Microcontroller features an ARM 32-bit Cortex-M3 core, operates at a maximum frequency of 72 MHz, and delivers 1.25 DMIPS/MHz at zero-wait memory access. It supports single-cycle multiplication and hardware division, making complex computational tasks fast and efficient.

The internal memory includes 64 KB of Flash and 20 KB of SRAM, providing ample space for diverse programs and necessary data. For clock and power management, the STM32F103C8T6 IC operates with a supply voltage of 2.0–3.6 V and includes POR, PDR, and a programmable voltage detection (PVD) system. Clock sources include a 4–16 MHz crystal oscillator, an 8 MHz factory-trimmed internal RC, and a 40 kHz internal RC, along with a PLL for CPU clocking and a 32 kHz oscillator for RTC with calibration support.

These features, combined with low-power modes such as Sleep, Stop, and Standby, allow for the design of energy-efficient and portable projects. VBAT support for RTC and backup registers is also provided. One of the key advantages of the Programmable STM32F103C8T6 IC is that engineers and developers can easily upload and execute their programs on the microcontroller.
