RV-8564-C2

Real Time Clock Module with I

All dimensions in mm typical

DESCRIPTION:

This very small SMD ceramic package has been specially designed to

combine the 32.768 kHz crystal unit with the CMOS-based oscillator and

real-time-clock circuit.

The calendar function tracks year, month, date, and day-of-the-week with

built-in century and leap-year flags. The clock function tracks minute and

second in 24-hour format. Programmable alarm setting and universal

timer functions increase flexibility.

For pick-and-place equipment, the parts are available in 12 mm tape:

7” (178 mm) reel with 1'000 parts

10” (254 mm) reel with 2'500 parts

13” (330 mm) reel with 5'000 parts
