High-precision temperature-compensated oscillator (DTCXO) equipped! RTC module suitable for automotive applications.
The "RA4000CE" is a real-time clock (RTC) module with a built-in crystal oscillator that features a high-precision temperature-compensated oscillator (DTCXO). In addition to enabling low-power operation, it complies with AEC-Q100, making it suitable for automotive applications. It is equipped with a rich set of features, including a time calendar circuit with automatic leap year correction from seconds to years, and a timestamp function that can record the occurrence of external or internal events and power detection status through self-monitoring, with the ability to record timestamps twice. 【Overview】 ■ Built-in 32.768 kHz crystal oscillator (frequency accuracy adjusted) ■ Wide operating temperature range: -40℃ to +125℃ ■ Interface method: SPI-Bus interface 3-wire, 4-wire ■ Low current consumption: 300nA Typ./3V ■ Timestamp: Timestamp recorded twice *For more details, please refer to the PDF document or feel free to contact us.
