1.2 Analog and RF Pins
1.2.1 Supply and Ground Pins
EVDD, DEVDD
EVDD and DEVDD are analog and digital supply voltage pins of the Atmel® AT86RF232
radio transceiver.
AVDD, DVDD
AVDD and DVDD are outputs of the internal 1.8V voltage regulators. The voltage
regulators can be configured for external supply.
For details, refer to Section 9.4.
AVSS, DVSS
AVSS and DVSS are analog and digital ground pins respectively. The analog and
digital power domains should be separated on the PCB.
1.2.2 RF Pins
RFN, RFP
A differential RF port (RFP/RFN) provides common-mode rejection to suppress the
switching noise of the internal digital signal processing blocks. At board-level, the
differential RF layout ensures high receiver sensitivity by rejecting any spurious
emissions originated from other digital ICs such as a microcontroller.
A simplified schematic of the RF front end is shown in Figure 1-2.

The RF port is designed for a 100 differential load. A DC path between the RF pins is
allowed. A DC path to ground or supply voltage is not allowed.
The RF port DC values depend on the operating state, see Chapter 7. In TRX_OFF
state, when the analog front-end is disabled (see Section 7.1.2.3), the RF pins are
pulled to ground, preventing a floating voltage.

3 Overview
AT86RF232
Typical values contained in this datasheet are based on simulations and testing.
Minimum and maximum values are available when the radio transceiver has been fully
characterized.
The Atmel AT86RF232 is a low-power 2.4GHz radio transceiver designed for consumer
ZigBee/IEEE 802.15.4, RF4CE, 6LoWPAN, and 2.4GHz ISM band applications. The
radio transceiver is a true SPI-to-antenna solution. All RF-critical components except
the antenna, crystal and de-coupling capacitors are integrated on-chip. Therefore, the
AT86RF232 is particularly suitable for applications like:
2.4GHz IEEE 802.15.4 and ZigBee systems
RF4CE systems
6LoWPAN systems
Wireless sensor networks
Residential and commercial automation
Health care
Consumer electronics
PC peripherals
The AT86RF232 can be operated by using an external microcontroller like Atmel AVR®
microcontrollers. A comprehensive software programming description can be found in
reference [6], AT86RF232 Software Programming Model.
