AX-SFEU-API-1-01-TB05 ON Semiconductor

AX-SFEU, AX-SFEU-API Ultra-Low Power, AT Command / API Controlled, Sigfox Compliant Transceiver IC for Up-Link www.onsemi.com and Down-Link OVERVIEW 10 GPIO pins 4 GPIO pins with selectable voltage measure Circuit Description functionality, differential (1 V or 10 V range) or AXSFEU and AX SFEU API are ultralow power single ended (1 V range) with 10 bit resolution single chip solutions for a node on the Sigfox network with 2 GPIO pins with selectable sigma delta DAC both up and downlink functionality. The AXSFEU chip output functionality is delivered fully ready for operation and contains all the 2 GPIO pins with selectable output clock necessary firmware to transmit and receive data from the 3 GPIO pins selectable as SPI master interface Sigfox network in Europe. It connects to the customer Integrated RX/TX switching with differential product using a logic level RS232 UART. AT commands are antenna pins used to send frames and configure radio parameters. The AXSFEU API variant is intended for customers Power Consumption wishing to write their own application software based on the Ultralow Power Consumption: AXSFLIB1GEVK library.
