RA8900CE Description

Short technical summary and product information.

The Epson RA8900CE is a Real-Time Clock (RTC) module designed for applications requiring accurate timekeeping. It is equipped with a high-precision Digital Temperature Compensated Crystal Oscillator (DTCXO) and a built-in 32.768 kHz crystal unit.

 

The module utilizes an I2C-Bus interface, supporting a 400 kHz communication speed. The interface voltage range is from 2.5 V to 5.5 V, with a temperature-compensated voltage range of 2.0 V to 5.5 V and a timekeeping voltage range of 1.6 V to 5.5 V. It provides selectable clock outputs at 32.768 kHz, 1024 Hz, and 1 Hz.

 

Key functions include a full calendar, alarm, timer, and an integrated temperature sensor. These features make the RA8900CE suitable for automotive applications such as car audio and car navigation systems, as well as other clock-related functions.

 

The RA8900CE is AEC-Q200 compliant, indicating its suitability for demanding automotive environments. Further technical details, application manuals, and packing information are available from Epson.
