With a 32-bit CPU and a clock speed of up to 48 MHz, it can be used for a variety of activities, from straightforward control to more intricate embedded systems.

Technical Specifications

● Operating Temperature Range

From -40 °C to 85 °C, the STM32F030RCT6 microcontroller is built to tolerate a wide working temperature range. It is suitable for use in tough climatic circumstances due to its wide temperature range.

● Maximum Clock Speed

The STM32F030RCT6 can easily handle real-time workloads with a maximum clock speed of 48 MHz and effectively execute instructions.

● ADC Resolution

The STM32F030RCT6’s integrated Analog-to-Digital Converter (ADC) has a resolution of 12 bits. This high-resolution ADC is perfect for sensor interface and data acquisition applications because it enables precise and accurate analog signal readings.

● Flash Program Memory

The microcontroller has 256KB of Flash program memory built in. Because this memory is non-volatile, you can keep your computer code there even if the power is turned off. A large amount of program memory gives room for complicated applications and makes firmware updates simple.

● Operating Supply Voltage

The STM32F030RCT6’s usual operational supply voltage ranges from 2.5V to 3.3V. This range allows for freedom in the design of power-efficient devices and provides compatibility with diverse power sources.

● Minimum and Maximum Operating Supply Voltage

The microcontroller’s operational supply voltage ranges from 2.4V to 3.6V at its maximum. In order to guarantee the device will operate steadily and dependably, adherence to these voltage restrictions is essential.

Features and Capabilities

● ARM Cortex-M0 Core

The ARM Cortex-M0 core, known for striking a balance between performance and power economy, serves as the foundation of the STM32F030RCT6. Tasks may be handled effectively by the Cortex-M0 core, making it suited for applications where power consumption is essential.

● GPIO and Peripheral Support

The General-Purpose Input/Output (GPIO) pins on the microcontroller provide flexible interaction with numerous external components. Additionally, it offers seamless communication and control capabilities by supporting a broad variety of peripherals, including UART, SPI, I2C, timers, and more.

● Analog Capabilities

An internal 12-bit Analog-to-Digital Converter (ADC) is a feature of the STM32F030RCT6. The ADC is an essential part of microcontrollers because it enables the device to transform analog signals, like voltage levels from sensors, into digital data that the microcontroller can handle. Applications that call for accurate measurements or sensor interfaces might benefit from the 12-bit resolution of the ADC’s exceptional accuracy and precision in translating analog signals.

The microcontroller can be utilized in many different applications, such as data acquisition systems, environmental monitoring, and analog signal processing, thanks to its analog capabilities.

● Low Power Modes

The STM32F030RCT6 microcontroller’s versatility in terms of low-power operation is one of its key benefits. It is ideal for battery-powered and energy-efficient applications because these low-power modes are made to save energy when the device is not in use.

Typically, the microcontroller supports a variety of low-power modes, including Sleep, Stop, and Standby. The CPU is suspended in sleep mode, although peripherals and interrupts continue functioning. The CPU and the majority of the peripheral devices are disabled in Stop mode, enabling the microcontroller to swiftly wake up when required. Almost all internal circuits are shut off in standby mode, which has the lowest power usage but a longer wake-up time. These low-power settings are essential for applications that need longer battery life and less energy usage.

● Connectivity

The microcontroller has a number of interfaces for communication, including UART, SPI, and I2C, making it simple to connect to peripherals and other devices. As a result, it is possible to integrate devices seamlessly into larger communication networks or IoT (Internet of Things) systems.
