The Cordless Voice Module (CVM) Development Kit consists 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 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.
