Descriptions:

The DS1337C is a low-power, I²C-interfaced RTC with integrated crystal compensation, ensuring high accuracy. It includes battery backup support, allowing continuous timekeeping during power interruptions. The device features two alarms, a programmable square-wave output, and a 56-byte NV SRAM for data storage.

Features:

• Low Power Consumption: 500nA timekeeping current (typical)
• Wide Voltage Range: Operates from 2.97V to 5.5V
• I²C Interface: Supports standard (100kHz) and fast (400kHz) modes
• Battery Backup: Maintains timekeeping during power loss
• Two Time-of-Day Alarms: Programmable for interrupt generation
• Programmable Square-Wave Output: Configurable frequencies
• 56-Byte NV SRAM: Non-volatile storage for user data
• Automatic Power-Fail Detection: Switches to backup supply
