Values contained in this datasheet are based on simulations and characterization of

other transceivers manufactured on a similar process technology. Final values will be

available after the device is characterized.

1 Overview

The AT86RF212 is a low-power, low-voltage 800/900 MHz transceiver specially

designed for low-cost IEEE 802.15.4, ZigBee

TM, and high data rate ISM applications.

For the sub-1 GHz bands, it supports low data rates (20 and 40 kbit/s) of the IEEE

802.15.4-2003 standard [2] and provides optional data rates (100 and 250 kbit/s) using

O-QPSK, according to IEEE 802.15.4-2006 [1]. Furthermore, proprietary High Data

Rates Modes up to 1000 kbit/s can be employed.

The AT86RF212 is a true SPI-to-antenna solution. RF-critical components except the

antenna, crystal, and de-coupling capacitors are integrated on-chip. MAC and AES

hardware accelerators improve overall system power efficiency and timing.

1.1 General Circuit Description

The AT86RF212 single-chip RF transceiver provides a complete radio interface

between the antenna and the microcontroller. It comprises the analog radio part, digital

modulation and demodulation including time and frequency synchronization, as well as

data buffering. The number of external components is minimized so that only the

antenna, a filter (at high output power levels), the crystal, and four bypass capacitors

are required. The bidirectional differential antenna pins are used in common for RX and

TX, i.e. no external antenna switch is needed. Control of an external power amplifier is

supported by two digital control signals (differential operation). The transceiver block

diagram is shown in Figure 1-1.
