OVERVIEW
Circuit Description
AXâSFEU and AXâSFEUâAPI are ultraâlow power
single chip solutions for a node on the Sigfox network with
both upâ and downâlink functionality. The AXâSFEU chip
is delivered fully ready for operation and contains all the
necessary firmware to transmit and receive data from the
Sigfox network in Europe. It connects to the customer
product using a logic level RS232 UART. AT commands are
used to send frames and configure radio parameters.
The AXâSFEUâAPI variant is intended for customers
wishing to write their own application software based on the
AXâSFâLIBâ1âGEVK library.
Features
Functionality and Ecosystem
⢠Sigfox upâlink and downâlink functionality controlled
by AT commands or API
⢠The AXâSFEU and AXâSFâAPI ICs are part of a
whole development and product ecosystem available
from ON Semiconductor for any Sigfox requirement.
