Product Description：

The GD32W515 series MCUs are built on the Arm® Cortex®-M33 core and integrate a single-stream 2.4GHz IEEE 802.11b/g/n MAC/Baseband/RF radio module on-chip. This series of Wi-Fi MCUs offers a maximum transmit power of 21dBm, a receiver sensitivity as high as -97.6dBm, and a total link budget of 118.1dBm, delivering excellent baseband and RF performance. It also features outstanding anti-interference capability with an Adjacent Channel Rejection (ACR) value up to 48dB, which effectively prevents strong signal interference and enhances signal reception stability.

Operating at a maximum frequency of 180MHz, the GD32W515 series MCUs are equipped with up to 2048KB of eFlash, 32MB of EXT Flash, and 448KB of SRAM, along with a wide range of enhanced I/Os and peripheral interfaces connected to two APB buses. They also include a 12-bit ADC, up to four general-purpose 16-bit timers, two general-purpose 32-bit timers, one basic timer, one PWM advanced timer, as well as standard and advanced communication interfaces. Additional peripherals comprise a TrustZone Control Unit (TZPCU), Digital Camera Interface (DCI), Touch Sensing Interface (TSI), a Quad-SPI Flash Interface (QSPI), and the newly added High-Performance Digital Filter (HPDF), specifically designed for external Sigma-Delta modulation, enabling high-precision audio signal processing.

The GD32W515 series MCUs support the TrustZone mechanism, providing chip-level hardware protection and offering users a robust and secure development platform. They have formally passed Arm's Platform Security Architecture (PSA) Level one and PSA Functional API certifications, as well as Wi-Fi certification authorized by the Wi-Fi Alliance (WFA), and RF FCC/CE compliance certifications. The GD32W515 series MCUs come with a complete set of development kits and a dedicated software development package for Wi-Fi modules, including hardware drivers, protocol stacks, and cloud connectivity. With these numerous excellent features, they offer versatile solutions for various application scenarios, particularly in fields such as smart homes, industrial IoT, and consumer electronics.
