1.3 Description

The CC115L is a cost optimized sub-1 GHz RF transmitter. The circuit is based on the popular CC1101 RF transceiver, and RF performance characteristics are identical. The CC115L value line transmitter together with the CC113L value line receiver enables a low-cost RF link.

The RF transmitter is integrated with a highly configurable baseband modulator. The modem supports various modulation formats and has a configurable data rates from 0.6 to 600 kbps.

The CC115L provides extensive hardware support for packet handling, data buffering, and burst transmissions.

The main operating parameters and the 64-byte transmit FIFO of CC115L can be controlled through a serial peripheral interface (SPI). In a typical system, the CC115L will be used together with a microcontroller and a few additional passive components.
