Functional Introduction
Integrated 2.4 GHz IEEE 802.15.4 Compliant Radio
CC2520 features a Direct Conversion Transceiver operating in the 2.4 GHz band with excellent receiver
sensitivity and robustness to interferers. The CC2520 radio complies with the IEEE 802.15.4 PHY
specification. The radio has 250 kbps data rate, 2 Mchip/s chip rate, and is suitable for systems targeting
compliance with worldwide radio frequency regulations covered by ETSI EN 300 328 and EN 300 440 class
2 (Europe), FCC CFR47 Part 15 (US) and ARIB STD-T66 (Japan).

Command strobes and configuration
registers. All user control goes through the
SPI.

+5 dB
-98 dBm
Yes, configurable frequency 1-16MHz
Instruction set (which includes the command
strobes as a subset) and configuration
registers. Command strobes may be
triggered by GPIO pins, which gives
excellent timing control. Improved status
information.
Only possible when crystal oscillator is
running.
Schmitt triggers on all digital inputs.
Highly flexible and configurable
XOSC starts automatically after reset (by
reset_n pin). Manual start of XOSC after
SRES instruction.

Hardware support for non-intrusive sniffing
of both transmitted and received frames.
