GigaDevice Launches 1st Gen Wi-Fi MCUs to Enhance Wireless Security in AIoT

Written by Stephen Vicinanza

GigaDevice launches 1st Gen Wi-Fi Microcontrollers (MCUs) to enhance wireless security in Artificial Intelligence of Things (AIoT). This is the latest launch of a member of the Arm Cortex-M33 core MCU portfolio. The MCU family is the GD32W515 series.

These new MCUs have a higher baseband and RF performance, and built-in Trustzone architecture, for extended reliability in hardware execution environments for secure data storage. This continues a high standard for the GD32 MCU family with solid compatibility between software and hardware. The GD32W515 products offer wireless connectivity development options for a variety of applications in smart homes.

Additionally, the GD32W515 is suited for industrial IoT and consumer electronics. The company feels that with enhanced processing capabilities and features that offer rich integration options, designs for those applications can be simplified.

The GD32W515 continues the GD32 series use of the Arm Cortex M-33 core, integrated with a 2.4GHz single-stream IEEE 802.11b/g/n MAC/Baseband/RF radio frequency module on-chip. The Arm Cortex M-33 core is based on the latest Arm v8-M ISA and supports DSP instruction extension as well as single-precision floating-point arithmetic unit (FPU).

The GD32W515 series provides up to 180MHz frequency, with as high as 2048KB of on-chip Flash, 448KB SRAM, and can carry up to 32MB external Flash. The Power supply voltage is 1.6V – 3.6V, and the I/Os can take up to 5V voltage levels.

The operating temperature is -40℃ to +85℃, complementing an industrial challenging environment design and development. The maximum transmit power is 21 dBm, and there is a signal receiving sensitivity of -97.6 dBm, along with a total link budget of 118.6 dBm. The provides a great deal of frequency and baseband performance.

The adjacent channel rejection (ACR) value can run as high as 48 dB, which effectively prevents strong signal interference while improving the stability of overall signal reception. The series also supports high transmission rates with an Iperf throughput of up to 50Mbps. In the laboratory setting that throughput reached 80 Mbps.

To further simplify the design and development of products the radio frequency (RF) module is on-chip, reducing the Bill-of-Materials and the need for external components.

One of the main attributes of the GD32W515 series is backed by an SDK that in addition to the hardware drivers, the software protocol stacks and cloud connections, and other functionally dedicated systems related to Wi-Fi modules are available.

There are a number of development environments and tools such as Keil MDK, GCC, and IAR EWARM, which are all fully supported. The operating systems cover a wide range of industrial and consumer applications all are embedded and include, FreeRTOS, uCOS, RT-Thread, and AIiOS Things have all been ported and additionally available Wi-Fi reference design solutions can be provided.

Mr. Eric Jin, Product Marketing Director of GigaDevice, said, “We will expand a wider variety of wireless MCU product portfolios to provide innovative shortcuts for the endless development needs in the AIoT era. With the excellent processing performance and accelerator of the Cortex®-M33 core, the new Wi-Fi MCU can support edge computing such as local voice recognition, keyword wake-up, and artificial intelligence algorithms such as TinyML. The TrustZone security architecture can also greatly improve the information security design of IoT devices, escorting users’ privacy and security in the era of big data with Internet of Everything.”
