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. The integrated Bluetooth LE 5.2 RF module extends the communication distance, increases throughput, enhances security, and saves power following the latest Bluetooth specifications. The 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.
The 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 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.
