Otherwise, this chapter describes the MCU peripheral requirements and the resources

needed to control a SIGFOX device.

6.2.1 Peripheral requirements

Peripherals and resource requirements critical to the MCU's ability to handle a given part

are as follows:

• SPI module is required for communication (MISO, MOSI, SCK, CS)

• GPIO is required for an acknowledge pin (ACK)

• Supply and GND pins to power-on the OL2385

6.2.2 Supported devices

This section identifies the models supported by the driver and describes the capabilities

of each model. The SIGFOX software driver supports the following devices:

OL2385 (Available)

• RF transceiver

• Carrier frequency is 160 MHz to 960 MHz

• ETSI, FCC and Japanese compliant

• 2 antenna inputs

• Independent RF switch (TX/RX or RX/RX)

• Up to +14 dBm output power

• 26 Channel Filter BW Options (4 kHz to 360 kHz)

• Smart polling

• Excellent phase noise

• Ultra-low power in receive mode

OL2361 (Software to be updated on demand)

• RF transmitter

• Carrier frequency is 310 to 915 MHz

• ETSI, FCC and Japanese compliant

• Multichannel fractional-N PLL

• One reference frequency (XTAL) for all bands

• Programmable FSK/ASK/OOK modulation characteristics

• Improved programmable and stabilized output power

• Low power consumption

6.2.3 Supported MCUs

The SIGFOX software driver supports MCUs listed in Table 3. These MCUs are a subset

of the MCUs supported by the MCUXpresso Software Development Kit layer.

This software driver is built on the Analog Middleware Layer (AML), which creates an

API abstraction layer for the desired Software Development Kit (SDK). The current

implementation includes abstractions for MCUXpresso SDK 2.3 and S32 SDK 0.8.4 EAR.

This allows support to be added for additional layers, such as the MCUXpresso SDK,

without having to change the SIGFOX software driver itself.
