Sunnyvale, Calif. – Spansion Inc. debuts a new family of power management integrated circuits (PMICs) for energy harvesting that can enable a greener Internet of Things (IoT) by eliminating the need for or extending the life of batteries in many IoT devices, ranging from wearable electronics to the nodes in wireless sensor networks. “Natural resources such as solar, vibration, and thermal variations are inexhaustible, green sources of energy that can be harvested to fully power or extend battery life in embedded applications,” said Spansion.
The Spansion Energy Harvesting family includes the MB39C811, an ultra-low-power buck PMIC with dual input that enables efficient harvesting from both solar and vibration energy; and the MB39C831, an ultra-low-voltage boost PMIC for solar or thermal. These devices work with Spansion FM0+ microcontrollers (MCUs), ultra-low-power microcontrollers (based on the ARM Cortex®-M0+ core) for industrial and cost-sensitive applications with low-power requirements.
The Spansion Easy DesignSim, an online design support tool which is said to include the industry's only energy-budget calculator, simplifies application design by calculating the energy-budget balance while providing a recommended bill of materials (BOM) list that can be purchased online.
Availability: Evaluation boards for the MB39C811 and MB39C831 are available. A wireless sensor node starter kit also is available.
