This range of modules provides a very low power SuperRegenerative receiver, combined with flash
programmable controller, supplied pre-programmed to operate with a suitable Keeloq Transmitter encoder.
The range from such a system can be up to 50 metres Line of Sight (LOS). The current consumption is
1.5mA however this may be reduced to only 1 – 2 uA by placing the device into sleep mode and turning off
the supply to the radio section. A supervisory processor can then wake the module from time to time to allow
it to check for the presence of radio data.
Custom versions of this product are available, please contact our sales department for further details
