Overview
The RX8025T-UC is a compact real-time clock (RTC) module designed for applications requiring precise timekeeping. It integrates a quartz crystal oscillator and CMOS IC to deliver accuracy within ±5 parts per million (ppm). Commonly used in embedded systems, the module supports I2C communication and operates across a wide temperature range (-40°C to +85°C), making it suitable for industrial and automotive environments. Its low power consumption ensures longevity in battery-backed applications.
Structure and Working Principle
The module consists of a 32.768 kHz tuning-fork quartz crystal oscillator and a dedicated RTC IC. The oscillator generates a stable frequency, which the IC processes to track time, date, and alarms. An onboard backup battery (optional) maintains timekeeping during power outages. The I2C interface allows seamless integration with microcontrollers, enabling read/write operations for time adjustment and data retrieval.
Key Features
The RX8025T-UC stands out for its high accuracy (±5 ppm), equivalent to a deviation of just ±0.43 seconds per day. This precision is critical for applications like data loggers and medical devices. Other features include a wide operating voltage range (1.6V to 5.5V) and minimal standby current (~0.35 µA), ensuring energy efficiency. Its small form factor (e.g., 3.2 x 1.5 mm) saves PCB space in compact designs.
Application Areas
Industrial automation systems rely on the RX8025T-UC for synchronized operations, such as event timestamping in PLCs. It’s also prevalent in smart meters and IoT edge devices. Consumer electronics, including digital cameras and wearables, use the module for clock functions. Automotive applications include infotainment systems and black boxes, where reliability under extreme conditions is essential.
Maintenance and Precautions
To ensure longevity, avoid exposing the module to mechanical vibrations or temperatures beyond its specified range. ESD protection measures (e.g., grounded workstations) are recommended during installation. For battery-backed units, periodic checks of the backup battery’s voltage are advised. Storage in anti-static bags with desiccants prevents moisture damage.
B2B Procurement Guide
Bulk buyers should prioritize suppliers with ISO-certified manufacturing facilities to guarantee quality. Lead times typically range from 4–8 weeks, so plan inventory accordingly. Request samples to validate performance in your specific application. Negotiate pricing for orders exceeding 1,000 units; tiered discounts often apply. Confirm RoHS and REACH compliance for international shipments.
