Real-time clock (RTCs)

High Accuracy Timekeeping Module PT7C4025T
Pericoms highly accurate RTC module maintains precise time across a broad
temperature range. This RTC module integrates crystal and temperature compensation
circuit into one unit, which provides enhanced reliability and ruggedness as well as less
susceptibility to aging, EMI, and vibration. It also provides low-current operation and
high accuracy comparable to other crystal-based solutions.
RTC with Integrated Crystal PT7C4337C
Pericoms high accuracy RTC with integrated crystal could help designers to reduce
development and testing time, and simplify testing process. It meets low timekeeping
voltage 1.2V with SOIC-16 standard package.
I2C Interface RTC
Pericoms I2C interface RTCs are all the lowest cost timekeeping options due to their
simple, small circuit and reduced pin count. They are offered in various package types
including SOP, DIP, MSOP, TSSOP and the smallest package DFN.
3-Wire Interface RTC
Many timekeeping applications require the use of either square wave or interrupt
function. If only one pin is available, the designer must choose the function to invoke. REAL TIME CLOCKS
