Product details
Overview
CC2500RGPR from Texas Instruments is a 2.4 GHz RF transceiver IC designed for low-power ISM band wireless systems. It integrates a configurable baseband modem supporting GFSK/FSK/MSK/OOK modulation, programmable data rates up to 500 kBaud, and on-chip 64-byte TX/RX FIFOs. Its primary circuit role is bidirectional RF signal transmission and reception in battery-powered remote control and human interface devices.
For engineers reviewing the CC2500RGPR datasheet, CC2500RGPR pinout, CC2500RGPR application, or CC2500RGPR equivalent, key selection considerations include its –104 dBm sensitivity at 2.4 kBaud, 13.3 mA RX current (250 kBaud), +1 dBm max output power, and QLP 4×4 mm 20-pin package compatibility with EN 300 328/FCC Part 15-compliant designs.
Technical Context
The CC2500RGPR implements a fully integrated RF front-end with a fast-settling PLL-based frequency synthesizer (90 µs settling time) and digital demodulator supporting multiple modulation schemes. Its analog baseband includes automatic frequency compensation (AFC), programmable channel filter bandwidth (58–812 kHz), and integrated temperature sensing.
Digital subsystem features hardware-accelerated packet handling-including sync word detection, address filtering, CRC generation/verification, and link quality indication (LQI)-all controlled via a 4-wire SPI interface. Wake-on-radio (WOR) enables ultra-low-power polling with 400 nA SLEEP mode current.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2.4 GHz RF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Si4432-B1B-FM | Sub-GHz only (433/868/915 MHz); higher output power (+20 dBm); no 2.4 GHz support. | Designed for long-range SRD applications (smart metering, industrial sensors); incompatible with ISM 2.4 GHz band. | Select only for sub-GHz regulatory requirements; not a functional substitute for CC2500RGPR's 2.4 GHz operation. |
| nRF24L01+ | Integrated MCU-less 2.4 GHz transceiver; same 20-pin QFN package; lower sensitivity (–80 dBm at 1 Mbps); no AFC or analog temperature sensor. | Optimized for Nordic's proprietary protocol stack; lacks hardware packet filtering flexibility and regulatory compliance features (e.g., EN 300 328 test modes). | Choose for cost-sensitive, high-volume consumer remotes where simplified firmware and lower BOM count outweigh sensitivity and compliance needs. |
Compared with Si4432-B1B-FM and nRF24L01+, the CC2500RGPR uniquely balances 2.4 GHz ISM band compliance, –104 dBm sensitivity, and hardware-assisted packet handling-making it suitable for applications demanding regulatory certification, low-SNR robustness, and flexible protocol implementation without MCU overhead.

FAQ
What is the operating voltage range for the CC2500RGPR?
The CC2500RGPR operates from 1.8 V to 3.6 V across all supply pins (VDD), with stable performance across this range. It integrates an internal voltage regulator that separates analog and digital domains, ensuring consistent RF performance even with varying battery voltage-critical for maintaining link reliability in CC2500RGPR-based wireless peripherals throughout discharge cycles.
Does the CC2500RGPR support FCC Part 15 and ETSI EN 300 328 compliance out of the box?
Yes, the CC2500RGPR is designed to meet FCC CFR47 Part 15 (US), ETSI EN 300 328 and EN 300 440 Class 2 (Europe), and ARIB STD-T66 (Japan) requirements. Its integrated features-including programmable channel filter bandwidth, automatic clear channel assessment (CCA), and spurious emission suppression-enable certified system-level compliance when implemented per TI's reference design and PCB layout guidelines for CC2500RGPR.
How does the CC2500RGPR achieve ultra-low-power operation in battery-powered devices?
The CC2500RGPR achieves ultra-low-power operation via multiple hardware features: 400 nA SLEEP mode with register retention, wake-on-radio (WOR) for autonomous polling, and current-optimized RX modes (e.g., 13.3 mA at 250 kBaud). Its integrated low-power RC oscillator eliminates crystal startup delay, enabling rapid transitions from sleep to active RX/TX-key for extending CR2032 battery life beyond 2 years in CC2500RGPR-based wireless keyboards.
What modulation schemes does the CC2500RGPR support, and how are they selected?
The CC2500RGPR supports OOK, 2-FSK, GFSK, and MSK modulation, selected via configuration registers (MDMCFG2.MOD_FORMAT). Each scheme offers distinct trade-offs: GFSK provides best spectral efficiency for dense 2.4 GHz environments, while OOK simplifies TX-only remote designs. All modulations are implemented in hardware, eliminating MCU-based waveform generation and reducing CC2500RGPR system latency and power consumption.
Can the CC2500RGPR interface directly with a microcontroller without external level-shifting?
Yes, the CC2500RGPR's digital I/O pins (SCLK, MOSI, MISO, CSn, GDOx) are fully 1.8–3.6 V tolerant and compatible with standard 3.3 V or 1.8 V microcontrollers. Its SPI interface requires no external level shifters, and the GDO pins can drive MCU interrupts directly. This simplifies board design and reduces BOM cost in CC2500RGPR-based systems such as wireless mice and game controllers.
