PRODUCT SPECIFICATION
nRF9E5 Single Chip Transceiver with Embedded Microcontroller and ADC
9 TRANSCEIVER SUBSYSTEM (nRF905)
9.1
The Transceiver has two active (RX/TX) modes and one power-saving mode when the
microcontroller is running.
9.1.1 Active Modes
9.1.2 Power Saving Mode
The transceiver mode is decided by the settings of TRX_CE, TX_EN
9.2
The nRF9E5 uses the Nordic Semiconductor ShockBurst™ feature. ShockBurst
makes it possible to use the high data rate offered by the nRF905. By embedding all
high speed signal processing related to RF protocol in the transceiver, the nRF905 offers
the micro controller a simple SPI interface. Data rate is decided by the interface-speed
the micro controller itself sets up. By allowing the digital part of the application to run at
low speed, while maximizing the data rate on the RF link, the nRF905 ShockBurst™
mode reduces the average current consumption in applications. In ShockBurst
Address Match (AM) and Data Ready (DR) notifies the MCU when a valid address and
payload is received respectively. In ShockBurst
generates preamble and CRC. Data Ready (DR) notifies the MCU that the transmission
is completed. All together, this means reduced memory demand and more available
resources in the MCU, as well as reduced software development time.
