1.1 General Description
AI7933CLD is a highly integrated IoT module that features an ARM® Cortex-M33 application processor,
a low power 1x1 802.11a/b/g/n/ac/ax dual-band Wi-Fi subsystem, a Bluetooth v5.2 subsystem, an
Audio subsystem with Cadence Tensilica HiFi4 processor and a Power Management Unit (PMU). The
Wi-Fi subsystem and a Bluetooth v5.2 subsystem offer feature-rich wireless connectivity at high
standards, and deliver reliable, cost-effective throughput from an extended distance. The AI7933CLD
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 AI7933CLD is based on ARM® Cortex-M33 with floating point microcontroller (MCU) including
SRAM/ROM memory. The module also supports rich peripheral interfaces, including USB2.0, SDIO, SPI
master, I2C, I2S, IR input, UART, AUXADC, PWM, and GPIOs.
These features are used to download and debug a project on EK-AI7933CLD.
