STEVAL-IFS010V1 STR9 ZigBee demonstration board for SN260 network processor
Introduction
This user manual describes the STEVAL-IFS010V1 STR9 ZigBee demonstration board hardware. As well as the block diagram and schematics of the demonstration board, a bill of materials and assembly instructions are also included. The STR9 ZigBee demonstration board provides SN260 ZigBee with interface to an application running on host processor. Please note that the demonstration board cannot be used in standalone mode without a host processor. The SN260 integrates a 2.4 GHz, IEEE 802.15.4-compliant transceiver with a 16-bit network processor (XAP2b core) to run EmberZNetTM, the ZigBee-compliant network stack. The SN260 accesses the EmberZNet API across a standard SPI module, allowing application development on a host processor. This means that the SN260 can be viewed as a ZigBee peripheral connected over a SPI. The XAP2b microprocessor is a power-optimized core integrated in the SN260. It contains integrated Flash and RAM memory along with an optimized peripheral set to enhance the operation of the network stack. Refer to STMicroelectronicsTM SN260 datasheet for additional information. This user manual must be read in conjunction with user manual UM0282 describing the STR9 dongle. These documents are available on www.st.com. Figure 1. STR9 ZigBee demonstration board

Connection of STR9 ZigBee demonstration board to STR9 dongle
This section provides additional information on how to connect the STR9 ZigBee demonstration board to the STR9 dongle (see Figure 3).
SPI chip select inputs (active low) There are 3 SPI chip select inputs: SPI_SEL0: this input is used to select the ZigBee module. It is connected to P80 pin of the STR9 dongle. SPI_SEL1: this inputs is used to select the MEMS. It is connected to P81 pin of the STR9 dongle. SPI_SEL2: this input is used to select the external device if any. It is connected to P82 pin of the STR9 dongle.
HOST_INT output (active low) The SN260 ZigBee processor generates an interrupt to the host processor (STR912xx) on the falling edge of HOST_INT. This signal is connected to P45 pin on the STR9 dongle which must be configured as an input with interrupt capability.
WAKE_UP input (active low) This input performs the wake up of the SN260 ZigBee processor. It is connected both to P55 pin of the STR9 dongle and to B22 button. If P55 is configured as an output, the ZigBee device can be woken up either by a falling edge on the signal connected to P55 pin or by pressing B22 button. If P55 is configured as an input with interrupt capability, a falling edge on the signal connected to P55 wakes up the ZigBee device and an interrupt to the STR9 dongle is generated by pressing B22 button.
