The QCC743/QCC744 is Wi-Fi 6 + BLE v5.4 +
                IEEE 802.15.4 (Thread and Zigbee-ready)  combo chipset for ultra low-power
            applications.

The QCC743/QCC744 includes two subsystems: 
- The wireless subsystem has 2.4 GHz radio, Wi-Fi 802.11b/g/n/ax, BLE v5.4, and 802.15.4 baseband/MAC designs.
- The microcontroller subsystem has a low-power 32‑bit RISC-V CPU with floating
                    point unit, DSP unit, high-speed cache, and memories. The embedded Power
                    Management Unit (PMU) controls the low-power modes. The microcontroller also
                    supports various security features.

The QCC743/QCC744 supports SDU,
            SD/MMC (SDH), SPI, UART, I^2^C, I^2^S, PWM, GPDAC, GPADC, ACOMP, and
            GPIO interfaces. QCC744 supports extra interfaces for camera, display,
            MJPEG, audio codec, and Ethernet.

- The QCC743 supports 19
                    GPIOs.
- The QCC744 supports 35 GPIOs.
