Features
1. Timekeeping: It tracks seconds, minutes, hours, day, date, month, and year with leap year compensation up to 2099.
2. Alarm Functionality: Offers two programmable time-of-day alarms with calendar alarm capabilities.
3. Oscillator: Equipped with a temperature-compensated crystal oscillator, ensuring precise timekeeping.
4. Power Management: Low-power operation supports battery backup, maintaining timekeeping during power failures.
5. I2C Interface: Communicates via a 2-wire I2C bus, making it easy to integrate into various systems.
6. Voltage: Operates at a supply voltage range of 2.97V to 3.63V (hence the -33+ designation for 3.3V).
7. Additional Features: Includes programmable square-wave output and a power-fail detection circuit.
These features make the DS1388Z-33+ suitable for applications requiring reliable timekeeping and low power consumption, such as data loggers, time-stamping devices, and various embedded systems.
Pinout
1. VCC: Main power supply input.
2. VBAT: Backup battery input for RTC operation when VCC is not present.
3. GND: Ground reference for the device.
4. SCL: Serial Clock input for I2C communication.
5. SDA: Serial Data input/output for I2C communication.
6. RST: Active-low reset input; resets the I2C interface.
7. SQW/INT: Square wave/Interrupt output; can be programmed to output a square wave or used as an interrupt signal.
8. X1, X2 (or sometimes unused in SOIC): Connections for an external 32.768 kHz crystal to provide a time base for the RTC (in some configurations, these pins might be internally connected or not accessible in the SOIC version).
Please verify these details with the specific datasheet of the DS1388Z-33+ to ensure accuracy for your application.
