InnoPhase - ULP smart Wi-Fi module HW Reference Design

InnoPhase has taken the ULP Talaria ONE radio and has coupled it with the industry leading low power Ambiq Micro Apollo Cortex M4F MCU and a high efficiency Skyworks FEM to create the world’s lowest power Wi-Fi module reference design.  Not only does the module require very little power, it is also “extremely smart” with the ability to run complex user apps that take full advantage of the wide range of I/O capability brought out to an easy-to-use edge connector.

The innovative software stack is written to exploit the Talaria ONE 802.11b hardware performance enhancements that enables ultra-low power, full spec Tx/Rx distance and high throughput along with minimal impact to overall performance when connected very high speed networks.

Coupled with this innovative module hardware design is a power and memory footprint optimized software stack. The full featured driver and complete TCP/IP stack have been developed from the ground up to take full advantage of the ULP Talaria ONE and Ambiq Apollo MCU components for maximum battery life, high Wi-Fi throughput and minimal MCU memory requirements. Completely configurable for user application requirements, the system software enables the absolute lowest power intelligent node for demanding battery based IoT applications.
