SINGAPORE--(BUSINESS WIRE)-- GigaDevice, a global semiconductor solutions provider, has officially introduced the new GD32F5HC Series 32-bit general-purpose microcontroller lineup. The new MCU family is designed to deliver high performance, compact integration, enhanced security, ultra-low power consumption, and rich peripheral support for next-generation Human-Machine Interface (HMI) and IoT Edge applications.
The GD32F5HC series expands GigaDevice’s Arm® Cortex®-M33 portfolio and is now available with samples, development boards, and complete technical documentation to support rapid evaluation and mass-production deployment.
Built on the Arm® Cortex®-M33 core, the GD32F5HC series operates at speeds up to 200 MHz and utilizes the efficient Arm®v8-M architecture. The chips integrate an advanced DSP hardware accelerator along with a single-precision floating-point unit (FPU), enabling faster real-time processing, control systems, and algorithm-driven applications.
Compared with similar products in the market, the series offers expanded memory capacity, including:
This large memory configuration allows developers to implement complex graphics frameworks, sophisticated algorithms, and high-speed data processing pipelines more efficiently.
The GD32F5HC series also includes a comprehensive hardware-based security architecture. TrustZone® technology provides core-level hardware security protection, while MPU and SAU support dual-layer access control mechanisms.
Additional security features include:
These capabilities help ensure firmware integrity and lifecycle-level device protection, which are becoming increasingly important under modern cybersecurity regulations.
The GD32F5HC series integrates a broad range of communication and interface options to support diverse embedded applications. The platform includes:
The QSPI and SQPI interfaces support external PSRAM and Flash memory with operating frequencies up to 45MHz, allowing expanded storage capabilities for demanding applications.
For analog functionality, the MCU includes a 12-bit ADC, integrated temperature sensor, and IFRP support for accurate signal acquisition and processing.
The timing subsystem features:
These components support precision waveform generation, motor control systems, and synchronized multi-axis operations.
System performance is further improved through DMA0/DMA1 with eight channels and a DMAMUX module, reducing CPU workload and improving data transfer efficiency.
The GD32F5HC series is engineered for both high-performance industrial applications and battery-powered consumer devices. The MCU supports multiple low-power operating modes, including run mode, sleep, deep sleep, and standby mode.
Key power specifications include:
The devices also integrate power management features such as POR/PDR, LVD, and BOR for improved operational stability.
Available package options include compact BGA64 and QFN56 configurations, including a highly compact 4×4mm design with up to 54 GPIO pins and eight wakeup IOs, making the series suitable for space-constrained industrial and consumer products.
To accelerate product development, GigaDevice provides full ecosystem support for the GD32F5HC series. The platform supports mainstream GUI frameworks with QSPI-driven display resolutions up to 400×400, enabling smooth and responsive HMI experiences for display-focused products.
Developers also gain access to:
In addition, the MCU series is compatible with major development toolchains including Arm® KEIL, IAR, and SEGGER, helping streamline development workflows and reduce time-to-market.
