Real Time Clock Modules

Epson

Low-power consumption real-time clock module

RX-4035SAThis real-time clock module series is engineered to contribute significantly to lowering power consumption in electrical devices, while ensuring highly accurate time information.
RX-4035LCThe RTCs are designed to be compatible with primary and secondary batteries, capacitors (one type of storage cell) and various other power sources.

 

Economical real-time clock with calendar, timer & interrupt functions

RX-4571LCThe RX-4571 work with low back-up voltages up to 1V. The 32.768kHz quartz is already integrated.
RX-4571NBThis real time clock offers a calendar with automatic leap year correction, CMOS output with 32.768 kHz, timer, alarm and interrupt.
RX-4571SAApplications can be heating cost allocators, metering, building and access control, home appliances and entertainment equipment, and point-of-sales terminals.

 

High stability serial interface real-time clock

RX-4803SAThis module is an serial interface RTC with a 32.768kHz DTCXO. In addition to a calendar and a clock counter function, this module provides other features including alarm function, fixed-cycle timer, time update and 32.768kHz output function.
