OVERVIEW
Circuit Description
www.onsemi.com
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.
Features
8 GPIO pins
2 GPIO pins with selectable voltage measure
functionality, differential (1 V or 10 V range) or
single ended (1 V range) with 10 bit resolution
2 GPIO pins with selectable sigma delta DAC
output functionality
2 GPIO pins with selectable output clock
3 GPIO pins selectable as SPI master interface
RX/TX switching Control
Functionality and Ecosystem
Sigfox up−link and down−link functionality controlled
by AT commands or API
The AX−SFJK and AX−SFJK−API ICs are part of a
whole development and product ecosystem available
from ON Semiconductor for any Sigfox requirement.
Other parts of the ecosystem include
Ready to go development kit
DVK−SFJK−[API]−1−GEVK including a 2 year
Sigfox subscription
Sigfox Ready
