RX-8025NBAC PURE SN

Real Time Clock Overview

The RX-8025NB:AC PURE SN is a Real Time Clock (RTC) IC manufactured by Epson Timing. It provides clock/calendar functions via an I2C, 2-wire serial interface. The device operates within a supply voltage range of 1.7V to 5.5V and features low current consumption, typically between 1.2µA and 1.8µA at 3V to 5V. It supports date formats including YY-MM-DD-dd and time formats in HH:MM:SS (12/24 hour). The component is housed in a 14-SOP package with a width of 5.00mm. It includes alarm functions and leap year compensation capabilities.

Real Time Clock Procurement Notes

This specific part number, RX-8025NB:AC PURE SN, is listed as End-of-Life (EOL) or discontinued by the manufacturer. Distribution channels indicate restricted availability or lack of stock. Verification of current lifecycle status and alternative sourcing through authorized distributors is required before procurement planning.

Real Time Clock Selection Notes

Designers should verify the compatibility of the 14-SOP footprint and I2C protocol with their system architecture. Given the EOL status, replacement strategies involving pin-compatible alternatives from the same family or cross-manufacturer equivalents like the PCF2127AT/2Y should be evaluated for long-term supply stability.

Real Time Clock Part Context

The RX-8025NB series belongs to Epson's line of RTC modules designed for low power and high accuracy applications. Variants such as RX-8025SA and RX-8025NB share similar functional characteristics but may differ in packaging, accuracy specifications, or suffix designations related to compliance or tape/reel configurations.
