The MediaTek MT7933CT is a highly integrated single chip with an ARM® Cortex-M33 applications processor, a low-power 1x1 802.11a/b/g/n/ac/ax dual-band Wi-Fi subsystem, a Bluetooth v5.0 subsystem, an audio subsystem with a cadence® Tensilica® HIFI4 processor, and a power management unit (PMU). The Wi-Fi subsystem and the Bluetooth v5.0 subsystem provide feature-rich, high-standard wireless connectivity and reliable, cost-effective throughput over long distances. The optimized RF architecture and baseband algorithm provide superior performance and low power consumption. MT7933CT is designed to support standards-based functionality in the areas of safety, quality of service, and international regulations to deliver the best performance to end users at all times, in any situation. MT7933CT Based on the ARM® Cortex-M33 with a floating-point microcontroller (MCU), including SRAM/ROM memory. The chip also supports a rich set of peripheral interfaces, including USB2.0, SDIO, SPI master, SPI slave, I2C, I2S, IR input, UART, AUXADC, PWM, and GPIO.
