Lucida, Inversa and Pharaoh are all suitable as an on-board solution, and we also have FPC options available. If you need sub-791MHz Pharaoh may be best, though this would depend on how your device is configured mechanically.
I have passed your details to your regional representative who will be in touch, in case you would like to provide some more detail mechanical information (e.g. batteries, display, installation/use case configuration). We offer a free design review service, handled by one of our FAEs, in order the help you select the best part and integrate it for the best performance.
