概述
Description
The DS1339C-33# is a low-power, I²C real-time clock (RTC) with a built-in temperature-compensated crystal oscillator (TCXO) and 56-byte NV RAM. It maintains accurate timekeeping with minimal power consumption, making it ideal for battery-backed applications.
Key features:
- I²C interface (up to 400 kHz)
- ±2ppm accuracy (0°C to +40°C)
- Battery backup (operates down to 1.8V)
- 56-byte user RAM (non-volatile)
- Alarms & timer functions
Commonly used in embedded systems, IoT devices, and data loggers where precise timekeeping is critical. The "33" denotes a 3.3V operating voltage, while "#" indicates a tape-and-reel packaging option.
For detailed specs, refer to the datasheet.
