General 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 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

performance and sweep-mode enables the MICRF002 to

be used with low cost, imprecise transmitters.
