Low-Energy Sensor Interface Accesses EFM32 MCUs

Electronica 2010 – Energy Micro now offers a generic low energy sensor interface to its EFM32 microcontroller (MCU) family. LESENSE function block enables autonomous monitoring of as many as 16 external sensors in the MCU’s sub-mA, deep-sleep mode. Able to run independently of the EFM32’s ARM Cortex-M3 core, LESENSE can help create integrated, ultra low power sensor designs. Suitable for battery-powered systems, the interface operates with virtually any type of analog sensor control scheme including capacitive, inductive, and resistive types. It is also configurable for use in autonomous capacitive touch pad- and slider based devices and gas and water metering products relying on inductive rotation sensors.
