RV-4162-C7
Real Time Clock Module with I2C Bus
DIMENSIONS
Package:
Recommended Solder Pad:
100% leadfree, RoHS - compliant
All dimensions in mm typical
DESCRIPTION:
Ultra small SMT ceramic package
with integrated 32.768kHz Crystal
Automotive qualified, according to
AEC-Q200 Rev. C
I2C Interface Address: D0h
Frequency-Offset Trimming Register
Programmable Alarm and Interrupt
Oscillator Fail Detection
This ultra small RTC Module has been specially designed for miniature
and cost sensitive high volume applications.
The very small SMT ceramic package combines the 32.768 kHz crystal
unit with the CMOS-based oscillator and real-time-clock circuitry. The
clock function provides tenths/hundredths of seconds, seconds, minutes
and hours. The calendar function tracks date, month, year and century
with automatic leap year compensation. Programmable CLKOUT
frequencies, alarm settings and watchdog function increase flexibility
using this device.
Watchdog Timer
Programmable Clock-Output
Time keeping mode down to 1.0 V
For pick-and-place equipment, the parts are available in 12 mm tape:
7” (178 mm) reel with 1'000 parts
7” (178 mm) reel with 3'000 parts
