Ambiq Micro, the US-based semiconductor developer backed by semiconductor technology producer Arm and IT equipment provider Fujitsu, has raised $29.1m in a round that included the Singapore state-owned EDBI according to DealStreetAsia.
The round, which has not been officially confirmed by Ambiq, reached an $11.4m first close in June this year and includes 29 investors according to a regulatory filing that also revealed its size.
Founded in 2010, Ambiq provides low-power semiconductors including ultra low-power microcontrollers which are based on a technology platform that allows chips to operate at very low voltages despite temperature and noise sensitivity.
The company has now raised a total of $135m according to press releases and securities filings, including a $34m round closed in January 2018 that was backed by unnamed investors. Fujitsu became an investor through a distribution partnership deal in 2015.
Arm took part in Ambiq’s $15m series C round in 2014, which was led by Kleiner Perkins Caufield & Byers (KPCB) and backed by Austin Ventures and Mercury Fund. The latter two had joined Arm, Huron River Ventures and undisclosed other investors for a $10m series B the year before.
