GD32W515TGQ6

General description

The GD32W515xx is a highly integrated 2.4GHz Wi-Fi System-on-Chip (SoC) that 

includes an ARM Cortex®-M33 processor with Trustzone, a single stream IEEE 

802.11b/g/n MAC/baseband/radio, a power amplifier (PA), and a receive low-noise 

amplifier (LNA). It is an optimized SoC designed for a broad array of smart devices for 

Internet of Things (IoT) applications. The Cortex®-M33 processor is a 32-bit processor 

that possesses low interrupt latency and low-cost debug. The Cortex®-M33 processor is 

a 32-bit processor that possesses low interrupt latency and low-cost debug. The 

characteristics of integrated and advanced make the Cortex®-M33 processor suitable for 

market products that require microcontrollers with high performance and low power 

consumption. The Cortex®-M33 processor is based on the ARMv8 architecture and 

supports a powerful and scalable instruction set including general data processing I/O 

control tasks, advanced data processing bit field manipulations and DSP.

The GD32W515xx device incorporates the Arm® Cortex®-M33 32-bit processor core 

operating at up to 180 MHz frequency to obtain maximum efficiency. It provides up to 

2048 KB on-chip Flash memory or support up to 32MB of EXT Flash memory and up to 

448 KB SRAM memory. An extensive range of enhanced I/Os and peripherals connected 

to two APB buses. The devices offer a 12-bit ADC, up to four general 16-bit timers, two

general 32-bit timers, one basic timer, one PWM advanced timer, as well as standard 

and advanced communication interfaces: up to two SPIs, a SQPI, a SDIO, two I2Cs, 

three USARTs, one I2S, an USBFS and a Wi-Fi. Additional peripherals as TrustZone 

protection controller union (TZPCU), digital camera interface (DCI), touch sensing 

interface (TSI), high-performance digital filter (HPDF), quad-SPI interface (QSPI) are 

included.

The device operates from a 1.62 to 3.63 V power supply and available in –40 to +85 °C 

temperature range. Several power saving modes provide the flexibility for maximum 

optimization between wakeup latency and power consumption, an especially important 

consideration in low power applications.

The above features make the GD32W515xx devices suitable for a wide range of 

applications, especially in areas such as industrial control, motor drives, user interface, 

power monitor and alarm systems, consumer and handheld equipment, gaming and GPS, 

E-bike, optical module and so on.
