Silicon Labs completes acquisition of energy micro

Based in Oslo, Norway, Energy Micro offers the industry's most energy-efficient portfolio of 32-bit microcontrollers based on the industry-leading ARM Cortex-M architecture and is developing multi-protocol wireless RF solutions also based on ARM architecture.

Energy Micro's ultra-low-power portfolio complements Silicon Labs' existing 32-bit Precision32(TM) mixed-signal MCUs and sub-GHz and ZigBee® wireless RF products and targets a rapidly growing embedded market. The acquisition greatly expands Silicon Labs' 32-bit MCU and wireless SoC portfolio, adding nearly 250 energy-friendly MCUs and new low-power wireless protocols such as Bluetooth LE.

Under the agreement, the shareholders of Energy Micro will receive an up-front payment of $115 million in cash, plus approximately $55 million in deferred and earn-out consideration. Energy Micro is expected to contribute approximately $7 million in revenue in the second half of 2013. Anticipated growth is expected to allow the transaction to be accretive on a non-GAAP basis by the end of 2014.
