Description

The ABRACON AB08X5 Real-Time Clock family

provides a groundbreaking 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 14 nA), these are

- Programmable low battery detection threshold

- Programmable analog voltage comparator

the first semiconductors based on

innovative

SPOT

(Subthreshold

Power

Optimized

• I C (up to 400 kHz) and 3-wire or 4-wire SPI (up

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

to 2 MHz) serial interfaces available

• Operating voltage 1.5-3.6 V

• Clock and RAM retention voltage 1.5-3.6 V

• Operating temperature –40 to 85 °C

• All inputs include Schmitt Triggers

• 3x3 mm QFN-16 package

timer and watchdog functions, and either an I C 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.
