AB0815中文资料AB0815 - 芯片, 实时时钟, RC/晶振模式, 256B RAM, VBAT, 16QFN数据手册ABRACON规格书

描述 Description

The AB0815 is a Real Time Clock provides a ground-breaking combination of ultra-low power coupled with a highly sophisticated feature set. With power requirements significantly lower than any other industry RTC (as low as 15nA), these are the first semiconductor products based on Abracon Corporation's innovative SPOT (Sub threshold Power Optimized Technology by Ambiq Micro) CMOS platform. The AB08XX 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. It serves as a full function RTC for host processors such as microcontrollers. The Power management features built into the AB08XX enables it to operate as a backup device in both line-powered and battery powered systems.
