Description

The CC1100E is a Sub-GHz high performance radio transceiver designed for very low power RF applications. It is intended for the Industrial, Scientific and Medical (ISM) and Short Range Device (SRD) frequency bands at 470-510 MHz and 950-960 MHz. The CC1100E is especially suited for wireless applications targeted at the Japanese ARIB STD-T96 and the Chinese Short Range Device Regulations at 470-510 MHz.

The CC1100E is code, package and pin out compatible with both the CC1101 [1] and CC1100 [2] RF transceivers. The CC1100E, CC1101 and CC1100 support complementary frequency bands and can be used to cover RF designs at the most commonly used sub-1 GHz license free frequencies around the world:

• CC1100E : 470-510 MHz and 950-960 MHz
• CC1101 : 300-348 MHz, 387-464 MHz and 779-928 MHz
• CC1100 : 300-348 MHz, 400-464 MHz and 800-928 MHz

The CC1100E RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate of up to 500 kBaud.

The CC1100E provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wakeon-radio.

The main operating parameters and the 64-byte transmit/receive FIFOs of the CC1100E can be controlled via an SPI interface. In a typical system, the CC1100E will be used with a microcontroller and a few additional passive components.
