Part Overview
Description
The DS1305 is an integrated serial alarm real-time clock (RTC) that manages all timekeeping functions. It counts seconds, minutes, hours, date of the month, month, day of the week, and year with leap-year compensation valid up to 2100. Additionally, it features a 96-byte, battery-backed NV RAM for data storage.
Features
Real-time clock with leap-year compensation
96-byte, battery-backed NV RAM
Two time-of-day alarms
Standard serial port interfaces (SPI or 3-wire)
Burst mode for reading/writing successive addresses
Multiple power supply pins for primary and backup power
Optional trickle charge output to backup supply
2.0V to 5.5V operation
20-pin TSSOP package
Optional industrial temperature range (-40°C to 85°C)
UL recognized
Applications
Timekeeping in embedded systems
Data logging
Alarm systems
Industrial control
Medical devices
