8. Onboard transceiver
USB radio sticks deRFusb
The main difference between the deRFusb-23E00/06/JTAG
and the deRFusb-
13E00/06/JTAG USB radio sticks is the built-in 2.4GHz or alternatively Sub-GHz transceiver
in combination with the appropriate onboard chip antenna.
deRFusb-23E00/06/JTAG - AT86RF231 transceiver
The low-power 2.4GHz transceiver is designed for industrial and consumer IEEE 802.15.4,
ZigBee ? , RF4CE, SP100 and high data rate ISM applications.
deRFusb-13E00/06/JTAG - AT86RF212 transceiver
The low-power, low-voltage 800/900MHz transceiver is designed for low-cost IEEE 802.15.4,
ZigBee ? and high data rate ISM applications available Europe and North America.
General transceiver description
These single-chip radio transceivers provide a complete radio transceiver interface between
an antenna and a microcontroller.
They comprise the analog radio transceiver and the digital modulation and demodulation in-
cluding time and frequency synchronization and data buffering. The number of external com-
ponents is minimized such that only the antenna, the crystal and decoupling capacitors are
required. The bidirectional differential antenna pins are used for transmission and reception,
thus no external antenna switch is needed.
An internal 128 byte RAM for RX and TX buffers the data to be transmitted or the received
data. Two on chip low dropout voltage regulators provide the internal analog and digital 1.8V
supply.
The transceivers further contain comprehensive hardware-MAC support (Extended Operat-
ing Mode) and a security engine (AES) to improve the overall system power efficiency and
timing.
9. Onboard flash (option)
A 2 GByte flash memory to store user defined data is optionally available using the deRFusb-
23E06/JTAG and deRFusb-13E06/JTAG USB radio sticks.
This flash memory is typically applied as mass storage device for user data. It works like a
Multimedia Card (MMC). Possible data bit modes are 1bit (default) and 4bit.
The flash is equipped with a memory controller and has a NAND flash architecture. It com-
plies with eMMC Specification Version 4.4. The temperature range for safe operation is from
- 25C° to +85C°.
