YQ8025T | High-Accuracy RTC with Integrated DTCXO
Product Introduction
The YQ8025T is a high-accuracy calendar RTC with an integrated digitally temperature-compensated crystal oscillator (DTCXO) — a domestic replacement for the EPSON RX8025T. Because the 32.768kHz temperature-compensated oscillator is integrated, no external crystal and no load-capacitor matching are required, simplifying PCB layout. The I²C interface, wide 1.6~5.5V supply and low power consumption suit long-term coin-cell timekeeping and high accuracy across the full industrial temperature range.
Core Advantages
- RX8025T replacement: I²C interface, domestic alternative to the EPSON RX8025T.
- DTCXO integrated: no external 32.768kHz crystal — simplified PCB, no crystal load-capacitor matching.
- High accuracy across temperature: the integrated temperature-compensated oscillator keeps calendar accuracy over the full industrial temperature range.
- Wide supply voltage: 1.6~5.5V, low power consumption for long-term coin-cell timekeeping.
- Supply: YQM ELECTRONICS supplies YQ8025T with fast samples, competitive pricing and FAE support for volume programs.

FAQ
Q: What is the difference between the YQ8025T and the YQ8563?
A: The YQ8025T integrates a DTCXO — no external crystal is required — while the YQ8563 uses an external 32.768kHz crystal. This is the key difference between the two.
Q: Does the YQ8025T need an external crystal?
A: No — the digitally temperature-compensated oscillator (DTCXO) is integrated, simplifying PCB layout and removing crystal load-capacitor matching.
Q: What supply voltage does the YQ8025T support?
A: 1.6~5.5V with low power consumption, suitable for long-term coin-cell timekeeping.
Q: Which products does the YQ8025T replace?
A: The YQ8025T is a domestic replacement for the EPSON RX8025T.
