GD32VW553 Series

The GD32VW553 series MCU supports Wi-Fi 6 and Bluetooth LE 5.2 wireless connectivity. To meet the requirements of real-time processing and efficient communication, the GD32VW553 series MCU incorporates an open-source instruction set architecture based on a RISC-V processor core, operating at a maximum clock frequency of 160 MHz. The integrated 2.4 GHz Wi-Fi 6 RF module complies with the IEEE 802.11ax standard and is backward compatible with IEEE 802.11b/g/n standards, ensuring compatibility across different network environments. It supports Orthogonal Frequency Division Multiple Access (OFDMA), enabling multiple devices to share channel resources and delivering up to 60% higher data transmission rates compared to Wi-Fi 4. It also supports Multi-User Multiple-Input Multiple-Output (MU-MIMO), allowing multiple devices to operate simultaneously without interference, enabling high-efficiency, low-latency communication in high-density multi-device scenarios.

The integrated Bluetooth LE 5.2 RF module extends communication range, increases throughput, enhances security, and improves power efficiency in accordance with the latest Bluetooth specifications. It provides a 2 Mbps high-speed data mode and multiple data rates of 125 kbps and 500 kbps, effectively reducing transmission time and improving sensitivity. It enables stable and high-speed wireless connectivity even in complex multi-device environments.

The GD32VW553 series integrates up to 4 MB Flash, 320 KB SRAM, and 32 KB configurable instruction cache (I-Cache), significantly improving CPU processing efficiency. While delivering strong wireless performance, the GD32VW553 also integrates a rich set of general-purpose wired interfaces. The power supply voltage ranges from 1.8 V to 3.6 V, and the device supports an operating temperature of up to 105 °C, making it suitable for applications such as industrial interconnect systems, lighting equipment, and smart socket panels.
