With power requirements significantly lower than any other industry RTC (as low as 14 nA), these are the first semiconductors based on innovative SPOTTM (Subthreshold Power Optimized Technology) CMOS platform. The AB08X5 includes on-chip oscillators to provide minimum power consumption, full RTC functions including battery backup and programmable counters and alarms for timer and watchdog functions, and either an I2C or SPI serial interface for communication with a host controller. Disclaimer: AB08X5 series of devices are based on innovative SPOT technology, proprietary to Ambiq Micro. |
