The CC113L is a cost optimized sub-1 GHz RF receiver for the 300–348 MHz, 387–464 MHz, and 779–928 MHz frequency bands. The circuit is based on the popular CC1101 RF transceiver, and RF performance characteristics are identical. The CC115L transmitter together with the CC113L receiver enable a low-cost RF link. The RF receiver is integrated with a highly configurable baseband demodulator. The modem supports various modulation formats and has a configurable data rate up to 600 kbps. The CC113L provides extensive hardware support for packet handling, data buffering, and burst transmissions. The main operating parameters and the 64-byte receive FIFO of CC113L can be controlled through a serial peripheral interface (SPI). In a typical system, the CC113L will be used together with a microcontroller and a few additional passive components.
