Singapore (April 22, 2026) — GigaDevice, a leading global supplier of semiconductor devices, today announced the official launch of the GD32F5HC series 32‑bit general‑purpose microcontrollers. Designed with compact size, high frequency operation, large memory, and strong security, while also offering ultra‑low power consumption and rich peripheral configuration, the new series expands the GD32 Arm® Cortex®‑M33 portfolio and delivers a powerful platform for next‑generation HMI and IoT Edge solutions. Samples, development boards, and full technical documentation are now available to support rapid evaluation and mass‑production deployment.
High‑Efficiency, Advanced Compute Performance and Integrated Security Delivering a Powerful Competitive Edge
The GD32F5HC series, built on the Arm® Cortex®‑M33 core, operates at a main frequency of 200 MHz, leveraging the efficient Arm®v8-M architecture, these chips feature an advanced DSP hardware accelerator and a single-precision floating-point unit (FPU) to accelerate real‑time control, and algorithm‑driven application tasks. The series features ultra‑large capacity in comparison to similar products, featuring up to 2048KB Flash, 320KB SRAM, and 32KB I‑Cache, enabling developers with large program storage needs to implement complex algorithms, graphics frameworks, and high‑speed data pipelines with ease. The GD32F5HC series also incorporates a comprehensive set of built-in security mechanisms. Featuring a TrustZone®‑enabled architecture delivering hardware‑level security protection and supporting dual‑level access control through MPU and SAU to reinforce security at the core, the series further extends its protection with dedicated hardware security resources including 2k bits eFuse for security key storage and full suite of cryptographic accelerators including TRNG (true random number generator), SHA, DES/3DES, AES, RSA/DH, and ECC.
End‑to‑end protection is supported through secure boot, secure storage, secure debugging, and secure upgrades, ensuring firmware integrity and safeguarding devices throughout their lifecycle, offering an increasingly critical level of security as modern products strive to meet stringent requirements under emerging regulations.
Rich Peripheral Resources and High‑Speed Connectivity at the Heart of Application Versatility
To meet the demands of multi‑application scenarios, the GD32F5HC series integrates a rich set of high-speed peripherals and communications interfaces. It includes 2x SPI/1x I2S, 1x SQPI, 1x QSPI, 2x I2C, 3x USART, and 1x USB FS OTG. QSPI and SQPI interfaces support external PSRAM/Flash memory, with frequencies up to 45MHz for expanded storage capacity. Analog peripherals feature 1x 12‑bit ADC and integrated temperature sensor and IFRP for high‑precision analog signal collection and processing.
A robust timing subsystem provides 1x 16‑bit advanced timer, 2x 32‑bit general timers, 4x 16‑bit general timers, and 1x 16‑bit basic timer, supporting precise waveform generation, motor control, and synchronized multi‑axis operation. System throughput is further enhanced by 8‑channel DMA0/DMA1 and DMAMUX module, ensuring efficient data movement and reduced CPU load.
Low‑Power Design and Universal Adaptability
Engineered for both performance‑driven and battery‑powered applications, the GD32F5HC series integrates multi‑mode power optimization; run mode, 30.56mA; sleep; deep sleep; standby, 3.63uA. The chip operates within a voltage range of 2.7~3.63V and covers a temperature range of -40℃~+105℃ combined with power management features such as POR/PDR, LVD, and BOR. Available in highly compact BGA64, 4×4mm, and QFN56 packages with up to 54 GPIO pins and 8 wakeup IO. Perfectly fitting complex, compact and high-density industrial and consumer applications.
Comprehensive Ecosystem Support for Rapid Development
The GD32F5HC series provides full ecosystem support, including mainstream GUI frameworks with QSPI driven resolution up to 400×400, allowing developers to easily create smooth human‑machine interaction interfaces for display‑centric products.
GigaDevice offers the free GD32 Embedded Builder IDE, GD‑LINK debugging tools, and the GD32 All‑In‑One Programmer, with additional mainstream support from Arm® KEIL, IAR, and SEGGER toolchains to streamline development and accelerate time‑to‑market.
