Product Description：

The GD32F505RET7 is a member of GigaDevice's GD32F505 series, a high-performance 32-bit general-purpose microcontroller unit (MCU) based on the Arm® Cortex®-M33 core.

Core and Performance: This chip adopts the Arm® v8-M architecture, with a main frequency of up to 280MHz. It features a built-in Double-Precision Floating-Point Unit (FPU) and DSP instructions, delivering a performance score of up to 1200+ CoreMark. It excels at handling complex algorithms and real-time control tasks.

Memory and Flexibility: The series offers up to 1024KB of on-chip Flash and 192KB of SRAM. It supports the "Scatter Loading" technique, allowing developers to flexibly allocate the capacity of code storage areas, data storage areas, and runtime memory according to application requirements.

High Real-Time Performance and Integration: The chip incorporates advanced technologies such as Event Links and Hardware Trigger Chains, enabling direct communication between peripherals without CPU intervention. This reduces event response latency to below 50ns, significantly enhancing system real-time performance. Simultaneously, it integrates a rich set of analog and digital peripherals.

Industrial-Grade Reliability and Security: Operating temperature range is -40°C to +105°C, and operating voltage is 2.6V to 3.6V. It features a built-in hardware encryption engine (supporting AES-256, SHA-256), a True Random Number Generator (TRNG), and a Memory Protection Unit (MPU), providing multi-layered security protection from hardware to firmware.
