CC1100RTKR

The Texas Instruments CC1100RTKR is a single-chip, low-cost, low-power RF transceiver IC. It is designed for low-power wireless applications and supports proprietary protocols. The device features a wide operating temperature range of -40 to 85 °C and is available in a VQFNP package.

Key electrical specifications include support for GMSK, 2(G)FSK, ASK, and OOK modulation schemes. It operates in the 300-348 MHz, 400-464 MHz, and 800-928 MHz frequency bands. The maximum transmit power is +10 dBm, with a best sensitivity of -111 dBm at 1.2 kBaud. The lowest receive current is 14.4 mA, and the maximum data rate is 0.5 Mbps. The transceiver also boasts a fast synthesizer settling time of 90 µs and a low sleep mode current consumption of 400 nA.

Digital features include on-chip support for sync word detection, address check, flexible packet length, and automatic CRC handling. An efficient SPI interface allows for programming all registers with a single burst transfer. The CC1100RTKR also offers a digital RSSI output, programmable channel filter bandwidth, and support for automatic Clear Channel Assessment (CCA).

This component is noted as 'NOT RECOMMENDED FOR NEW DESIGNS' by the manufacturer, though it remains available for existing customers. New designs should consider an alternate product like the CC1101.
