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
