Device Overview

Summary

Low-power, low-voltage 700/800/900MHz transceiver designed for low-cost IEEE 802.15.4-2011, ZigBee Pro, 6LoWPAN, and high data rate ISM applications available in China, Europe, North America, and Japan. The transceiver offers an extreme 120 dB link budget (-110 dBm receiver sensitivity / +10 dBm transmit power). It is a true SPI-to-antenna solution providing a complete radio transceiver interface between the antenna and the microcontroller. MAC and AES hardware accelerators improve overall system power efficiency and timing.

It comprises the analog radio transceiver and the digital demodulation including time and frequency synchronization, and data buffering. All RF-critical components are integrated on a single chip minimizing the number of required external components to the antenna, crystal and decoupling capacitors. The bidirectional differential antenna pins, used for transmission and reception, eliminate the need for an external antenna switch.

An internal 128 byte RAM buffers transmit and receive data. Two on chip low dropout (LDO) voltage regulators provide the internal analog and digital 1.8V supply.
