Ambiq Micro Inc. (Westlake Hills, Texas) has pushed the AM08XX and AM18XX real-time clock (RTC) chips which may be the world’s lowest power RTC chips. According to Ambiq, the typical active current of the AM08XX and AM18XX is between 15 and 55 nanoamperes.

The AM08XX and AM18XX chips are designed to help control power-sensitive applications such as smart cards, real-time backup, wireless sensors, tags and security tokens, utility meters, dataloggers and handsets.

The AM08XX product family is a functionally different RTC family that replaces existing, more power-hungry RTC products. The AM18XX product family includes all functions in the AM08XX family but also includes power management functionality that enables system-level power savings. Variants of the AM08XX product family are footprint compatible with popular RTC products currently on the market, and they are available in SOIC-8 and QFN-16 package types. The AM18XX-EVK evaluation kit, which provides access to all input and output signals on the RTC, comes in the form of a motherboard that connects to a PC through a USB cable.

Ambiq starts volume production, and the price of the ICs has not been set.
