Abstract: This application note describes how to use the extended RAM that is available in some multiplexed-bus real-time clocks (RTCs). General OverviewThe DS1685/87 and DS17x85/87 include an additional block ...

Abstract: Dallas Semiconductor offers two real-time clocks (RTCs), the DS1371 and DS1374, that utilize a 32-bit counter to maintain time. Both devices also provide a 24-bit count down watchdog/alarm counter that can provide one of three fu...

Abstract: This application note discusses various contributors to battery capacity consumption in a battery-backed application, and how to predict battery lifetime in a system. A designer should be able to use this application note to dete...

Abstract: This application note describes how to interface the DS32x35 real-time clock with an 8051-type microcontroller. It also provides a schematic of the application circuit and example software code for implementing basic operating ro...

Abstract: This application note is intended to demonstrate an application using the DS1307 Real-Time Clock with a Microchip PIC microcontroller. The software example includes basic operating routines, and a schematic of the application cir...

Abstract: Recent U.S. legislation increased the daylight saving time (DST) period by four weeks. This change will affect systems that adjust for DST by using real-time clocks (RTCs) with an integrated DST adjustment. This note discusses is...
