GigaDevice GD32F503/505 — High‑Performance Arm Cortex‑M33 MCUs for Industrial AI & Motor Control

GigaDevice's new GD32F503 and GD32F505 series bring industry‑leading performance to embedded AI and industrial control. Based on the Arm® Cortex®‑M33 (Arm v8‑M), these MCUs deliver up to 280MHz, DSP acceleration, and an FPU for demanding signal processing and control tasks.

Performance, memory and peripheral flexibility

Key highlights optimized for AI, motor control and industrial automation:

• CPU: Cortex‑M33 up to 280MHz (GD32F505) and 252MHz (GD32F503).
• Compute: Up to 4.10 CoreMark/MHz and 1.51 DMIPS/MHz; built‑in DSP and single‑precision FPU.
• Memory: Up to 1MB Flash and 192KB SRAM with flexible Code‑Flash / Data‑Flash / SRAM partitioning.
• Peripherals: Multiple ADCs (3× 3Msps), DAC, comparator, up to 3 USART, 2 UART, 2 I2C, 3 SPI, 2 I2S, 2 CAN‑FD and USBFS.
• Timers: Rich timing system with 32‑bit and multiple 16‑bit timers plus PWM advanced timers for precise motor and power control.
• Power & temp: 2.6V–3.6V operation and industrial temperature range (‑40°C to +105°C) with three low‑power modes.

Security, reliability and ecosystem

GD32F503/505 integrate chip‑level security and industrial reliability features that matter for connected devices:

• Secure boot and secure firmware update (SBSFU) with anti‑rollback and integrity/authenticity checks.
• Hardware security engine: SHA‑256, AES‑128/256, TRNG and unique UID for device identity.
• Robust reliability: enhanced EMC, high ESD protection (contact 8kV / air 15kV) and HBM/CDM resilience across zap tests.
• Functional safety support: STL test library and Safety Package with TÜV IEC 61508 SC3 (SIL2/SIL3) artifacts, FMEDA and safety self‑test libraries.

These features make the GD32F503/505 ideal for digital power, BMS, motor drives, industrial automation, robotics and autonomous cleaning robots where performance, safety and longevity are essential.

Developer support is comprehensive: multiple packages (LQFP, QFN, BGA), datasheets, software libraries, GD32 Embedded Builder IDE, GD‑link debug tools, GD32 All‑In‑One Programmer, plus support from Arm KEIL, IAR and SEGGER toolchains.

Samples and development boards are available now; mass production begins in December. Request samples, secure evaluation boards, and start prototyping today to accelerate your embedded AI and motor control projects.
