The DS1338Z-33+T&R is an integrated circuit (IC) component developed by Maxim Integrated. It is a low power, Real-Time Clock (RTC) IC that provides accurate timekeeping functionality. Below is an overview of its key features:
1. Real-Time Clock (RTC): The DS1338Z-33+T&R enables accurate timekeeping with seconds, minutes, hours, day, date, month, and year information. It supports leap year compensation up to the year 2100.
2. 56-Byte Nonvolatile RAM: It includes 56 bytes of nonvolatile RAM (NV RAM) for storing various data, such as user information, alarms, and control registers.
3. I2C Interface: The IC uses the I2C (Inter-Integrated Circuit) interface for communication with the microcontroller or other devices. It supports both standard-mode (up to 100 kHz) and fast-mode (up to 400 kHz) I2C communication.
4. Low Power Consumption: With a low operating current of 400 μA (typical), the DS1338Z-33+T&R is designed to minimize power consumption, making it suitable for battery-operated devices requiring long-lasting performance.
5. Oscillator and Battery Backup: It features an integrated crystal oscillator circuit that allows it to maintain accurate timekeeping even in the absence of a power supply. It can be powered by either a coin cell battery or an external power source
