ST STM32F100C4T6A High-Performance Mainstream Arm Cortex-M3 32-Bit MCU

Shenzhen Mingjiada Electronics Co., Ltd., as a seasoned supplier in the electronic components industry, has been supplying the high-performance mainstream Arm Cortex-M3 32-bit microcontroller STM32F100C4T6A for an extended period.

STM32F100C4T6A Microcontroller Overview

The STM32F100C4T6A is a 32-bit microcontroller based on the Arm Cortex-M3 core. It is an entry-level product within the STM32F1 series, but its excellent performance-to-cost ratio has made it widely adopted in industrial control, consumer electronics, and other fields. The STM32F100C4T6A is packaged in an LQFP48 package and operates within a temperature range of -40°C to +85°C, meeting the requirements of most industrial environments.

STM32F100C4T6A microcontrollers incorporate the high-performance ARM®Cortex®-M3 32-bit RISC core operating at a 24 MHz frequency, high-speed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 8 Kbytes), and an extensive range of enhanced peripherals and I/Os connected to two APB buses. All devices offer standard communication interfaces (up to two I2Cs, two SPIs, one HDMI CEC, and up to three USARTs), one 12-bit ADC, two 12-bit DACs, up to six general-purpose 16-bit timers and an advanced-control PWM timer.

In terms of core performance parameters, the STM32F100C4T6A operates at a maximum frequency of 24MHz, features 16KB of Flash memory and 4KB of SRAM, and provides a rich set of peripheral interfaces, including:

Up to 37 high-speed I/O ports

16-bit timer (3 units)

12-bit ADC (1 unit, 10 channels)

SPI/I2C/USART communication interfaces (2 each)

USB 2.0 full-speed interface (1 unit)

As a member of the STM32F1 series, the STM32F100C4T6A inherits the series' high cost-effectiveness while maintaining the low-power characteristics of the STM32 product line, with power consumption as low as 150µA/MHz in run mode and as low as 2µA in standby mode, making it ideal for battery-powered devices.
