Replacing STM32F415 with GX32F415 32-bit MCU in Alarm Systems

Security alarm systems are safety and protection equipment used in industrial plants, buildings, and equipment protection. The core of the system lies in reliably extracting abnormal features from sensor signals within the power budget and completing the closed loop from detection to response within milliseconds. Traditional 8-bit or low-end 16-bit MCUs lack sufficient computing power, while application-processor-class chips consume too much power. The GX32F415 32-bit high-performance MCU precisely meets the alarm system‘s requirements for sufficient computing power and low power consumption.

The GX32F415 32-bit high-performance MCU chip is based on the Cortex-M4 core, with an ultra-high main frequency of 168MHz, and includes a floating-point unit (FPU). It also supports DSP instructions and memory protection (MPU) to enhance application security. Its excellent performance enables pin-to-pin compatibility with the STM32F415, allowing rapid board-level replacement without software or hardware modifications.

The GX32F415 integrates high-precision ADCs, CAN bus, multiple communication peripherals, and large-capacity storage resources. It features strong computing capability, high real-time performance, excellent anti-interference capability, and stable operation over a wide temperature range. It has built-in high-speed memory (up to 1MB of Flash and 320KB of SRAM), and up to 4KB of backup-domain SRAM. It offers abundant enhanced I/O ports and peripherals connected to two APB buses. The full 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.
