AX−SFAZ/D

AX-SFAZ, AX-SFAZ-API

Ultra-Low Power,

AT Command / API Controlled,

Sigfox) Compliant

Transceiver IC for Up-Link

and Down-Link

OVERVIEW

Circuit Description

AX−SFAZ and AX−SFAZ−API are ultra−low power

single chip solutions for a node on the Sigfox network with

both up− and down−link functionality. The AX−SFAZ chip

is delivered fully ready for operation and contains all the

necessary firmware to transmit and receive data from the

Sigfox network in Australia/New Zealand (SIGFOX RCZ4

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−SFAZ−API variant is intended for customers

wishing to write their own application software based on the

AX−SF−LIB−1−GEVK library.

Features

Functionality and Ecosystem

• Sigfox up−link and down−link functionality controlled

by AT commands or API

• The AX−SFAZ and AX−SF−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−SFAZ−[API]−1−GEVK including a 2 year

Sigfox subscription

♦ Sigfox Ready® certified reference design for the

AX−SFAZ and AX−SFAZ−API ICs

General Features

• QFN40 5 mm x 7 mm package

• Supply range 2.7 V* − 3.6 V

• −40°C to 85°C

• Temperature sensor

• Supply voltage measurements

*Includes the RF frontend module, circuit as in Figure 5.

The AX−SFAZ chip alone is operational from 1.8 V to 3.6 V,

a supply voltage below 2.0 V is considered an extreme condition.

• 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

Power Consumption

• Ultra−low Power Consumption:

♦ Charge required to send a Sigfox OOB packet at

24 dBm output power: 0.28 C

♦ Deepsleep mode current: 100 nA

♦ Sleep mode current: 1.3

mA

♦ Standby mode current: 0.5 mA

♦ Continuous radio RX−mode at 922.3 MHz :

34 mA

♦ Continuous radio TX−mode at 920.8 MHz

230 mA @ 24 dBm

High Performance Narrow−band Sigfox RF Transceiver

• Receiver

♦ Carrier frequency 922.3 MHz

♦ Data−rate 600 bps FSK

♦ Sensitivity

−128 dBm @ 600 bps, 922.3 MHz, GFSK

♦ 0 dBm maximum input power

• Transmitter

♦ Carrier frequency 920.8 MHz

♦ Data−rate 600 bps PSK

♦ High efficiency, high linearity integrated power

amplifier

♦ Maximum output power 24 dBm

Applications

Sigfox networks up−link and down−link.
