Description
A range of miniature single in line (SIL) hybrid modules providing complete four channel Radio
Receiver/Decoder systems available in either AM or FM. When used with the 110-AM or 120-FM series
pocket keyfobs a complete remote telemetry system is obtained with up to 150 metres range.
The module consists of a front end super-heterodyne or super-regen RF receiver with an embedded
microcontroller decoding a highly secure Keeloq protocol signal.
The module has an easy-to-use 'LEARN' facility, and is capable of learning up to 50 unique keyfob encoders.
The module requires a 5V power supply and provides a direct LED drive showing data reception and four
digital data outputs. The outputs may be programmed for momentary or latching configuration.
The modules have flash re-programmability feature to enable field re-programming of the controller.

HiR6 Versions
HIRK-315
HIRK-433
HIR6-433
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
