IR LRM2 Radio Module Features Summary
Document p/n: 9S02-9027-A002 Rev.A
2. Features Summary
The IR LRM2 is designed to replace Remtron products with less cost and improved performance. Its host interface
is compatible with previous LRM(2PCA-7954-xxxx) series.
• Direct electrical compatibility to LRM (2PCA-7954-xxxx) interface
• On-board wireless SoC– The interface is controlled by an on-board Silicon Labs EFR32FG13 SoC. The
EFR32FG13 Flex Gecko SoC includes both a high-performance radio transceiver and a high performance, low
power Micro-Controller.
• Minimum buffers/Minimum Delay – IR LRM2 firmware is implemented to provide a “almost transparent”
operation; transmission and reception delays are kept to a minimum
• Support for different Modulation modes– The IR LRM2 family is designed to support multiple different RF
Modulations (2FSK and 4FSK), which is transparent to Host firmware.
These different aspects are covered in the rest of this document.
