CC1070 CC1070 Single Chip Low Power RF Transmitter for Narrowband Systems Applications • Narrowband low power UHF wireless data transmitters • 402 / 424 / 426 / 429 / 433 / 447 / 449 / 469 / 868 and 915 MHz ISM/SRD band systems • TPMS – Tire Pressure Monitoring Systems • • • • AMR – Automatic Meter Reading Wireless alarm and security systems Home automation Low power telemetry Product Description CC1070 is a true single-chip UHF transmitter designed for very low power and very low voltage wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 402, 424, 426, 429, 433, 447, 449, 469, 868 and 915 MHz, but can easily be programmed for multi-channel operation at other frequencies in the 402 470 and 804 - 940 MHz range. CC1070 will be used together with a microcontroller and a few external passive components. The CC1070 is especially suited for narrowband systems with channel spacings of 12.5 or 25 kHz complying with ARIB STD T-67 and EN 300 220. The CC1070 main operating parameters can be programmed via a serial bus, thus making CC1070 a very flexible and easy to use transmitter. In a typical application Features • True single chip UHF RF transmitter • Frequency range 402 - 470 MHz and 804 - 940 MHz • Programmable output power • Low supply voltage (2.3 to 3.6 V) • Very few external components required • Small size (QFN 20 package) • Pb-free package • Data rate up to 153.6 kBaud • OOK, FSK and GFSK data modulation • Fully on-chip VCO SWRS043A • Programmable frequency makes crystal temperature drift compensation possible without TCXO • Suitable for frequency hopping systems • Suited for systems targeting compliance with EN 300 220, FCC CFR47 part 15 and ARIB STD T-67 • Development kit available • Easy-to-use software for generating the CC1070 configuration data Page 1 of 54 CC1070 Table of Contents 1
