AX-SFJK, AX-SFJK-API Ultra-Low Power, AT Command / API Controlled, Sigfox) Compliant Transceiver IC for Up-Link and Down-Link www.onsemi.com OVERVIEW Circuit Description AX−SFJK and AX−SFJK−API are ultra−low power single chip solutions for a node on the Sigfox network with both up− and down−link functionality. The AX−SFJK chip is delivered fully ready for operation and contains all the necessary firmware to transmit and receive data from the Sigfox network in Japan (SIGFOX RCZ3a region). It connects to the customer product using a logic level RS232 UART. AT commands are used to send frames and configure radio parameters. The AX−SFJK−API variant is intended for customers wishing to write their own application software based on the AX−SF−LIB−1−GEVK library.
