SRW1042 5000m Wireless Transmission Module
SRW1042 highly integrated, low cost TRx module which was covered from 240MHz to 930MHz ISM band. The extremely low receive sensitivity couple with industry leading +30dBm output power ensures the extended range and improved link performance. Lowest BOM cost
and smallest PCB size 30mm×20mm. The module comply with RoHs standard, -40℃~+85℃ temperature range, it was also integrated wakeup timer, temperature sensor, FIFO, power-on- reset, GPIOs, high-performance ADC and DSP based modem. The modem performs demodulation, filtering, packet handling for increasing flexibility and performance which could make the design simplest and allow couple with the lower-end MCUs. We supply the RF design so that the customer could use it simply. It is not necessary for the customer to debug the module when they use it.

23· SPI Interface
The module communicates with the external MCUs via the standard 4-wire SPI (NSEL, SCLK, SDI and SDO). Through SPI, the MCUs write/read the content of register to/out of the module. A SPI transaction is a 16-bits sequence, MSB is the symbol of write and read (read”0”, write”1”), followed by a 7-bits address field, and then 8-bits data field. The following graphic is the SPI timing; the detailed infos please refer to the datasheet.
Besides the byte read/write mode, the SPI interface contains a burst read/write mode which allows for reading/writing sequential registers without having to re-send the SPI address. You can refer to the datasheet for the burst mode timing.
You can use the SPI peripheral of the MCU to communicate with the RF module. If the MCU you use do not has SPI peripheral, you can also use the I/O ports of the MCU to simulate the SPI protocol and use them to communicate with the RF module. At this time, only 4 I/Os are used. So you can choose the cheapest MCU to design your product with our RF module.
