It operates across 1.8–3.8 V supply and supports industrial applications up to +125°C ambient temperature.
For engineers reviewing the CC2520RHDR datasheet, CC2520RHDR pinout, CC2520RHDR application, or CC2520RHDR equivalent, key selection criteria include its QFN28 (RHD) package, 4-wire SPI interface, hardware-accelerated MAC functions (CRC, CCA, ACK), 768-byte on-chip RAM for frame processing, and compliance with FCC Part 15, ETSI EN 300 328, and ARIB STD-T66.
Technical Context
The CC2520RHDR implements a direct-conversion I/Q transceiver architecture with on-chip VCO, LNA, PA, and RF filters. Its DSSS O-QPSK modulation conforms to IEEE 802.15.4-2006 PHY layer specifications at 250 kbps and 2 MChip/s chip rate across 2394–2507 MHz.
Hardware-assisted MAC features include automatic preamble generation, synchronization word detection, CRC-16 computation/verification, frame filtering, pending-bit handling, and full CCM-mode encryption/authentication. The device integrates a random number generator and supports CC2420 register-level compatibility mode for migration.

FAQ
What is the primary function of the CC2520RHDR in a ZigBee® network?
The CC2520RHDR serves as a 2.4 GHz IEEE 802.15.4-compliant RF transceiver that handles physical layer (PHY) and medium access control (MAC) functions-including modulation/demodulation, packet framing, CRC, clear channel assessment, and AES-128 encryption-for ZigBee® end devices, routers, and coordinators. In a typical implementation, the CC2520RHDR interfaces with an external microcontroller via SPI to form a complete ZigBee® node.
Does the CC2520RHDR require an external crystal oscillator?
Yes, the CC2520RHDR requires a 32 MHz fundamental-mode crystal connected to XOSC32M_Q1 and XOSC32M_Q2 pins. The device includes on-chip tuning capacitors (±100 ppm adjustment range) to compensate for crystal tolerance and PCB parasitics, eliminating need for external load capacitors in most designs.
How does the CC2520RHDR manage power consumption in battery-operated devices?
The CC2520RHDR supports three flexible power modes: active RX/TX, idle, and power-down (<1 µA). Its 18.5 mA RX current at -50 dBm and 33.6 mA TX current at +5 dBm-combined with hardware-accelerated MAC tasks-minimize host MCU wake time. This enables multi-year operation on coin-cell batteries in sensor nodes when paired with duty-cycled sleep scheduling.
Is the CC2520RHDR pin-compatible with the CC2420?
No, the CC2520RHDR is not pin-compatible with the CC2420 due to different package footprints (QFN28 RHD vs. QFN32 RHB) and revised pin assignments. However, it offers CC2420 compatibility mode at the register and command-strobe level, allowing firmware reuse and simplified migration paths for existing CC2420-based designs with board layout revision.
What regulatory certifications does the CC2520RHDR support out of the box?
The CC2520RHDR is designed to meet key regional radio regulations when implemented per TI's reference design: FCC CFR47 Part 15 (USA), ETSI EN 300 328 and EN 300 440 Class 2 (Europe), and ARIB STD-T66 (Japan). Its integrated RF front-end, calibrated output power, and built-in spectral mask compliance features eliminate need for external filtering in certified system-level implementations.
