The Cordless Voice Module (CVM) Development Kit consist of two development boards with headsets, enabling voice connection setup. It enables the easy and cost-effective development of cordless applications and significantly reduces the time-to-market.

All the features of the module are accessible through the pins on the development board, while buttons and LED’s statuses can be changed and checked. The CVM kit comes with the Athena development environment, an Eclipse based IDE that provides a development environment for CR16C+ series of microcontrollers, and a GNU cross compiler/linker for CR16 – removing the need for an external µController.

All Dialog’s modules are fully encapsulated Systems in Package (SiP) ICs, which have their own protocol stacks and application interfaces already on board. Designers can therefore develop products without needing an in-depth understanding of the complex DECT, DECT 6.0 or JDECT protocols. The modules are also “type approved” for DECT, DECT 6.0 and JDECT. This significantly reduces R&D costs and the need for expensive RF testers can be virtually eliminated.
