Technical Details & Description

2.4 GHz transceiver — what it is, what it does

The Texas Instruments CC2500-RTR1 is a low-power 2.4 GHz RF transceiver (TxRx Only) designed for the ISM band above 1 GHz. It handles modulation formats 2FSK, GFSK, MSK, and OOK, making it suitable for proprietary and standard protocols like Zigbee or BLE at data rates up to 500 kBaud. The part is controlled entirely through an SPI interface, so the host MCU handles the protocol stack — this is a radio front-end, not a full wireless SoC.

Receiver sensitivity and link budget

Sensitivity is -104 dBm at 2.4 GHz.

Current draw and power budget

Transmit current is 11.1 mA to 21.5 mA; receive current is 13.3 mA to 19.6 mA.

marks the CC2500-RTR1 as Active — no end-of-life or last-time-buy risk for current designs. The base part number CC2500 is a long-running TI product line, so supply continuity is stable.

Frequently asked questions

Is CC2500-RTR1 equivalent to CC2500?

Yes — the RTR1 suffix indicates tape-and-reel packaging; the base die and RF performance are identical to the CC2500. No functional difference.

What is CC2500-RTR1's listed type on this component line?

It is classified as TxRx Only — a pure RF transceiver without an integrated microcontroller. The host MCU communicates via SPI.
