Description

The MICRF002 is a single chip ASK/OOK (ON-OFF Keyed) RF receiver IC. This device is a true "antenna-in to data-out" monolithic device. All RF and IF tuning is accomplished automatically within the IC which eliminates manual tuning and reduces production costs. The result is a highly reliable yet low cost solution.

The MICRF002 is a fully featured part in 16-pin packaging, the MICRF022 is the same part packaged in 8-pin packaging with a reduced feature set (see "Ordering Information" for more information).

The MICRF002 is an enhanced version of the MICRF001 and MICRF011. The MICRF002 provides two additional functions over the MICRF001/011, (1) a Shutdown pin, which may be used to turn the device off for duty-cycled operation, and (2) a "Wake-up" output, which provides an output flag indicating when an RF signal is present. These features make the MICRF002 ideal for low and ultra-low power applications, such as RKE and remote controls.

All IF filtering and post-detection (demodulator) data filtering of MICRF002/022 is provided within the MICRF002, so no external filters are necessary. One of four demodulator filter bandwidths may be selected externally by the user.

The MICRF002 offer two modes of operation; fixed-mode (FIX) and sweep-mode (SWP). In fixed mode the MICRF002 functions as a conventional superhet receiver. In sweep mode the MICRF002 employs a patented sweeping function to sweep a wider RF spectrum. Fixed-mode of MICRF002/022 provides better selectivity and sensitivity performance and sweep mode enables the MICRF002 to be used with low cost, imprecise transmitters.
