The GD32W515 series of MCUs continue to use the latest Arm® Cortex®-M33 core, integrated with a 2.4GHz single-stream IEEE802.11b/g/n MAC/Baseband/RF radio frequency module on-chip.
The Cortex®-M33 core is based on the new Armv8-M instruction set architecture and supports the DSP instruction extension and single-precision floating-point arithmetic unit (FPU).
The included optional TrustZone hardware security mechanism supports independent storage access space, enhancing the security and flexibility of such applications.
The wireless GD32W515 series has a maximum transmit power of 21 dBm, a signal receiving sensitivity of -97.6 dBm, and a total link budget of 118.6 dBm to provide leading class baseband and radio frequency performance.
It also has a superior anti-interference ability. The adjacent channel rejection (ACR) value is as high as 48 dB, which can effectively prevent strong signal interference and improve the stability of signal reception.
This series of MCU supports high transmission rates with Iperf throughput of up to 50 Mbps, and in laboratory test conditions, the throughput reached up to 80 Mbps.
The radiofrequency (RF) module is fully integrated on-chip to simplify designs, effectively reducing the number of external components and thus saving BOM costs.
The GD32W515 series MCU provides a maximum frequency of 180MHz, up to 2048KB of on-chip Flash, 448KB of SRAM, and supports up to 32MB of external Flash.
The power supply voltage is 1.6-3.6V, while the I/O ports can withstand 5V voltage levels. The standard industrial temperature range of –40 to +85°C is supported as well.
The chip has built-in rich peripheral resources including:
one 12-bit ADC
four general-purpose 16-bit timers
two general-purpose 32-bit timers
one basic timer
one PWM advanced timer
two SPIs
one SDIO
two I2Cs
three USARTs
one I2S
one USB2.0 FS
one Wi-Fi wireless interface
Other peripherals include TrustZone control unit (TZPCU), digital camera interface (DCI), touch sensing interface (TSI), Quad SPI Flash Interface (QSPI), and a new High-performance Digital Filter (HPDF). It can be used for external Σ-Δ modulation to achieve high-precision audio signal processing.
The GD32W515 series of MCUs is supported by a complete set of development kits. In addition to the documentation and firmware library, the software development kit (SDK), which includes hardware drivers, software protocol stacks, cloud connections, and other functions dedicated to Wi-Fi modules, is also available.
Various development environments and tools such as Keil MDK, IAR EWARM, and GCC are fully supported.
Embedded operating systems such as FreeRTOS, µCOS, RT-Thread, and AliOS Things have been ported, and available Wi-Fi reference design solutions can be provided as well.
GD32W515 is PSA certified, for more info see here.
The GD32W515P-EVAL full-featured evaluation board, which is based on the QFN56 package, supports development, debugging, and complete function demonstration. The GD32W515T-START entry-level kit, which is based on the QFN36 package, can be used to evaluate Wi-Fi-related development. For further information, please contact Special-IND.
