LRM Radio Module – Host Interface Specification Document p/n: 9S02-7954-A001 Rev.A 1. 1.1 Introduction Introduction Purpose A new family of RF module, the LRM family, is being developed by Cattron. This family includes high-selectivity radios covering several RF bands used world-wide for remote control applications. They are built around a common architecture, and present a uniform host interface definition. The host interface is used for data communication and radio configuration. 1.
LRM Radio Module – Host Interface Specification Document p/n: 9S02-7954-A001 Rev.A 2. Features Summary Features Summary The LRM design addresses in first place Unity applications requirements. Its interface however is general enough to allow compatibility to other legacy Cattron products. • Direct electrical compatibility to Unity RF interface – The interface is defined for natural integration to Unity product line. • On-board CPU – The interface is controlled by an on-board Renesas CPU.
