Introduction
The Acsip AI917L represents our lowest power Wi-Fi 6 plus Bluetooth LE 5.4 solution, making it ideal for ultra-low power IoT wireless devices using Wi-Fi®, Bluetooth, Matter, and IP networking for secure cloud connectivity. These modules are optimal for developing battery-operated devices that need long battery life.
Both models share the same core architecture, including an ultra-low power Wi-Fi 6 plus Bluetooth Low Energy (LE) 5.4 wireless CPU subsystem, and an integrated microcontroller (MCU) application subsystem, security, peripherals, and power management subsystem.
The wireless subsystem consists of a multi-threaded Network Wireless Processor (NWP) running up to 160 MHz, baseband digital signal processing, analog front end, 2.4 GHz RF transceiver, and integrated power amplifier.
The application subsystem consists of an ARM® Cortex®-M4 running up to 180 MHz, embedded SRAM, FLASH, ultra-low power sensor hub, and matrix vector processor.
The ARM® Cortex®-M4 is dedicated for peripheral and application-related processing, while the NWP runs the wireless and networking stacks on independent threads, thus providing a fully integrated solution for a wide range of embedded wireless IoT applications.
