Ambiq launches nanoampere RTC chips
The chips are intended to help control power-sensitive applications such as real-time backup, wireless sensors, tags, smart cards and security tokens, utility meters, dataloggers and handsets.
The AM08XX product family is a functionally diverse RTC family that replaces existing, more power-hungry RTC products. Variants of the AM08XX product family are footprint compatible with popular RTC products currently on the market and cover SOIC-8 and QFN-16 package types and I2C and SPI serial communications options and varieties of on-chip SRAM up to 256-bytes. The AM18XX product family includes all functions in the AM08XX family but also includes power management functionality that enables system-level power savings.
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 did not provide a price for the ICs or the evaluation kit or state whether it is able to supply in volume.
