General Description  

The MICRF009 is a single chip, ASK/OOK (ON-OFF Keyed) RF receiverIC. It provides thesamefunction but with performance enhancements over earlier QwikRadio® receivers. Two key improvements are: higher sensitivity

(typically 6dBhigher than the MICRF002)  andfaster recoveryfromshutdown (typically 1ms). Just like all other

members ofthe QwikRadio® family, the MICRF009 achieves low power operation, a very high level of integration, and it is particularly easy to use.

Features

•  High sensitivity (–104dBm)

•  Fast recoveryfrom shutdown (1ms)

•  300MHz to 440MHz frequency range

•  Data-rate upto 2.0kbps (fixed-mode, Manchesterencoding)

•  Low power consumption

–  2.9mA fully operational (315MHz)

–  0.15µA in shutdown

–  290µA in polled mode (10:1 duty-cycle)

•  Shutdown input

•  Automatic tuning, no manual adjustment

•  Very low RF re-radiation at the antenna

•  Highly integrated with extremely low external part count

•  1ms time to good data

Applications

•  Automotive remote keylessentry (RKE)

•  Long range RF identification

•  Remote fan and light control

•  Garage door and gate openers
