V850 MCU platform for Continua-certified blood glucose meter agent

August 21, 2011

Julien Happich-August 21, 2011

Renesas Electronics launched a Continua demonstration platform based on the its V850 energy-efficient microcontroller (MCU) with certified Continua Blood Glucose agent software. Implementing a blood glucose meter as defined by the Continua Health Alliance, the platform shows how the V850 MCUs implement complete software functionality at a level of power efficiency that ensures long battery life.

The energy-efficient V850 MCUs, at about 350uA/DMIPS with up to 1 megabyte (MB) of Flash memory and integrated USB function support, make it possible to handle the added software load without sacrificing the long battery life that end users have come to expect.

The Renesas Electronics V850 Continua demonstration platform implements a set of guidelines for blood glucose meters developed by the Continua Health Alliance. Alliance guidelines use key industry standards to ensure an end-to-end architecture from personal medical devices to hospital information systems. One such standard is ISO/IEEE 11073, which defines a medical device, the measurements that it makes, and a protocol for communicating the measurement data. For the underlying communication transmission method, the Continua guidelines specify open standards such as USB, Bluetooth and ZigBee.

While the Continua demonstration platform uses USB, the V850ES/Jx3-L MCUs can also support Bluetooth and ZigBee functionality. Further, the demonstration platform implements an optional persistent metric store (PM Store) to support off-line storage of measurement data. This PM Store enables a medical device to save measurement data until the device can connect to a network and automatically send the data.
