General Description
AI7931HD is a highly integrated stamp module that features an ARM® Cortex-M33 application processor,
a low power 1x1 802.11a/b/g/n/ax dual-band Wi-Fi subsystem, a Bluetooth v5.0 subsystem and a Power
Management Unit (PMU). The Wi-Fi subsystem and a Bluetooth v5.0 subsystem offer feature-rich
wireless connectivity at high standards, and deliver reliable, cost-effective throughput from an extended
distance.
Optimized RF architecture and baseband algorithms provide superb performance and low power
consumption.
AI7931HD is designed to support standard based features in the areas of security, quality of service and
international regulations, giving end users the greatest performance any time and in any circumstance.
The AI7931HD is based on ARM® Cortex-M33 with floating point microcontroller (MCU) including
SRAM/ROM memory. The chip also supports rich peripheral interfaces, including UART, SDIO, I2C, SPI, I2S,
and auxiliary ADC. These features are used to download and debug a project on EK-AI7931HD.
