GD32VW553 series MCU

Leading RF computing performance

To fulfill the requirements of real-time processing and efficient communication, the GD32VW553 series MCU incorporates a new open-source instruction set architecture with the RISC-V processor core, boasting a maximum clock frequency of 160 MHz. Additionally, it incorporates advanced DSP hardware acceleration, a double-precision floating-point unit (FPU), instruction expansion interfaces, and various other resources. Through excellent microarchitecture design, this combination results in outstanding energy efficiency, while providing flexibility for scalability.

The integrated 2.4 GHz Wi-Fi 6 RF module follows the IEEE 802.11ax standard and is backward compatible with the IEEE 802.11b/g/n standard, ensuring its suitability for different network environments. It supports Orthogonal Frequency Division Multiple Access (OFDMA) enabling multiple devices to share channel resources, resulting in 60% higher data transmission rate compared to Wi-Fi 4. Additionally, it offers support for Multi-User Multiple-Input Multiple-Output (MU-MIMO), enabling multiple devices to work simultaneously without interfering with each other, thus achieving high-efficiency and low-latency communication in multi-device high-density access scenarios.

The integrated Bluetooth LE 5.2 RF module extends the communication distance, increases throughput, enhances security, and saves power following the latest Bluetooth specifications. It provides 2 Mbps high-speed data mode and multiple rates of 125K/500Kbps to effectively reduce transmission time and improve sensitivity. It facilitates the establishment and configuration of stable and high-speed wireless networks even in the case of multiple devices and complex environments.

The new Combo Wireless MCU offers advanced baseband and RF performance with a variety of additional features. It supports the wireless coexistence protocol based on the Package Traffic Arbitration (PTA) mechanism, significantly reducing same-frequency interference caused by Wi-Fi and Bluetooth; thereby enhancing the stability of signal reception. Additionally, it is equipped with Automatic Gain Control (AGC) in a high dynamic range to effectively enhance signal quality. Thanks to the Target Wake Time (TWT) of Wi-Fi 6, GD32VW553 can flexibly schedule the sleep and wake-up time, improving energy-saving efficiency and meeting the access requirements of wireless devices with low power consumption and long battery life.

High integration and security

The new GD32VW553 series integrates up to 4MB Flash, 320KB SRAM, and 32KB configurable Instruction Cache (I-Cache) to greatly improve CPU processing efficiency. The GD32VW553, delivering excellent wireless performance, is also equipped with rich universal wired interfaces, including three U(S)ART, two I2C, one SPI, one four-wire QSPI, and up to 29 programmable GPIO pins. Its built-in components include two 32-bit general-purpose timers, two 16-bit general-purpose timers, four 16-bit basic timers, one PWM advanced timer, and one 12-bit ADC. The power supply voltage ranges from 1.8 V to 3.6 V and it offers high temperature up to 105℃ to meet the application scenarios such as industrial control interconnection, lighting equipment, and socket panels.

The GD32VW553 series also provides multiple security features to streamline secure connection and management of high-performance wireless devices. It supports the Wi-Fi Protected Access (WPA) security feature, incorporating new WPA3 encryption technologies for both personal and corporate networks. The hardware encryption and decryption engine support DES, triple DES, AES, and Hash algorithms. It also supports Public Key Cryptographic Acceleration Unit (PKCAU) to ensure confidentiality and data integrity during wireless communication. The True Random Number Generator (TRNG) can provide unpredictable data for key generation across a variety of security protocols, further enhancing the system’s security capabilities.
