MediaTek MT5932 is a highly integrated chipset containing a microcontroller unit (MCU), a low power 1x1 11n single-band Wi-Fi subsystem and a power management unit (PMU). The MCU is an ARM Cortex-M4 processor with floating point unit.

Key features

  • Highly integrated with RF, MCU and memory
  • Low power mode with RTC
  • Target Applications: standalone SDIO module, single-cloud connectivity

( MT5932 Product Brief )

The Wi-Fi subsystem contains 802.11b/g/n radio, baseband and MAC designed for low power and high throughput application development. It also contains a 32-bit RISC CPU that could fully offload the application processor. MT5932 also supports interfaces including UART, I2C, SPI, I2S, PWM, SDIO and ADC.
