MCUs pair high flash capacity with security
The GD32F5HC series of 32-bit general-purpose MCUs from GigaDevice features a 200-MHz Arm Cortex-M33 core with DSP and FPU capabilities. Hardware-based security, ample on-chip memory, and integrated peripherals target both consumer and industrial designs.
On-chip memory includes 2 MB of flash, 320 KB of SRAM, and 32 KB of instruction cache. Multichannel DMA controllers handle complex algorithms, graphics frameworks, and high-speed data flows. QSPI and SPI interfaces enable external PSRAM and flash expansion at up to 45 MHz.
Peripherals include a 12-bit ADC with an integrated temperature sensor and an infrared interface for analog signal processing. Multiple 16-bit and 32-bit timers, along with a real-time clock, enable waveform generation, motor control, and synchronized multi-axis operation.
Security features combine Arm TrustZone with a 2-kbit eFuse for key storage and hardware cryptographic accelerators. Secure boot, storage, debugging, and firmware updates help maintain system integrity across the device lifecycle.
The MCUs operate from a 3.3-V supply and offer four power-saving modes: sleep, deep sleep, standby, and SRAM sleep. Devices are available in BGA64 and QFN56 packages with up to 54 GPIOs.
