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 configurable baseband modulator. The modem supports various modulation formats and has a configurable data rates from 0.6 to 600 kbps.
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 via an SPI interface. In a typical system, the CC115L will be used together with a microcontroller and a few additional passive components.

Texas Instruments has introduced a family of RF transceivers for sub-1GHz radio bands used for applications such as remote controls, toys, home and building automation, and security systems.
The CC115L transmitter, CC113L receiver and CC110L transceiver are intended
“They answer the market’s increasing need for simple, low-cost connectivity for applications that require both long battery life and long range wireless connection,” said Erling Simensen, product marketing manager at TI.
The CC11xLDK-868-915 and CC11xLEMK-433 development kits provide complete hardware performance testing and software development platforms for the new product family.
The kits also offer new low-cost reference designs, with a compact PCB antenna for 433, 868, 915MHz, featuring a reduced component count and complete design ready for FCC and ETSI certification.
Features include a startup-time of 0.24ms from power down to RX or TX.
