GXSC MCU Replacement Solution for the STM32F417 Series in Industrial PLCs

Programmable Logic Controllers (PLCs) serve as control terminals in the field of industrial automation, performing functions such as equipment start/stop, logic interlocks, analog control, and data exchange, thereby ensuring the continuous, safe, and stable operation of industrial production lines. These functions require a 32-bit MCU with high real-time processing and floating-point capabilities.

GXSC’s industrial-grade MCUs are based on the Cortex-M4 core and feature a hardware FPU (floating-point unit). With a clock speed of up to 168 MHz, they integrate a rich set of industry-specific peripherals and natively support parallel communication via multiple interfaces, including Ethernet, CAN, USB, USART, SPI, and I2C. Their core advantages include wide operating temperature range, high immunity to interference, strong real-time performance, abundant resources, and outstanding cost-effectiveness. They provide a one-stop solution for the comprehensive requirements of embedded PLCs, including logical operations, high-speed I/O control, analog data acquisition, multi-bus networking, and edge data processing, making them ideally suited for the development and design of small- and medium-sized industrial PLCs and customized industrial control PLCs.

The full GXSC MCU series includes 3 12-bit ADCs, 2 DACs, 1 low-power RTC, 12 16-bit timers (2 of which can be used for motor control), 2 32-bit timers, and 1 true random number generator. It also provides a variety of standard and advanced communication interfaces: 3 I2C, 3 SPI (including 2 I2S), 4 USART, 2 UART, 1 full-speed USB OTG and 1 high-speed USB OTG interface, 2 CAN channels, 1 SDIO/MMC interface, 1 Ethernet interface, and 1 digital camera interface.

Furthermore, the GXSC MCU operates at temperatures ranging from -40 to +105°C, with a supply voltage of 1.8 to 3.6 V. Thanks to a series of power-saving modes, this MCU is suitable for low-power applications.

Conclusion: Industrial PLC control systems built on Guoxin Sichen’s 32-bit MCUs can comprehensively achieve on-site industrial logic control, precise analog signal regulation, and high-speed motion control, significantly enhancing the real-time performance and reliability of industrial control systems. With a mature hardware and software ecosystem, outstanding cost-effectiveness, and high mass-production stability, this solution is the preferred control solution for small and medium-sized embedded industrial PLCs.
