The MM6104 from Morse Micro is a Wi-Fi HaLow (IEEE 802.11ah) Wireless SoC that supports sub-1 GHz frequency bands from 750 to 950 MHz. It delivers a data rate of up to 43.3 Mbps and features an ultra-high linearity LNA and Power Management Unit (PMU) that supports ultra-low-power operation modes for extended sleep times and lower power consumption of battery-operated STA client devices. This SoC has an on-chip power amplifier (PA) for typical low-power, low-cost devices and also supports an external PCB-mount PA or front-end module (FEM) for ultra-long-reach applications. It is available in a QFN48 package that measures 6 x 6 mm and can be controlled via GPIO, UART, I2C, PWM, SDIO 2.0, and SPI host interfaces. The SoC is ideal for low-power, long-reach IoT applications.
