Features
1. RTC Functionality: Tracks seconds, minutes, hours, day, date, month, and year, with built-in leap year compensation up to 2100.
2. I2C Interface: Communicates through a 2-wire I2C interface, allowing for easy integration with microcontrollers and other I2C-enabled devices.
3. 32 kHz Output: Provides a square-wave output at 32.768 kHz for driving external clocking needs.
4. Battery Backup: Maintains timekeeping in the event of a power failure using an external battery.
5. Wide Voltage Range: Operates at supply voltages from 2.3V to 5.5V.
6. Low Power Consumption: Designed for low power applications, helping to extend battery life.
Overall, the DS1338Z-33+ is a versatile and reliable RTC solution for embedded systems requiring accurate timekeeping.
Pinout
1. VCC: Power supply pin (3.3V).
2. GND: Ground pin.
3. SDA: Serial Data Input/Output. Used for transferring data to and from the RTC over the I²C bus.
4. SCL: Serial Clock Input. Used to synchronize data movement on the I²C bus.
5. SQW/OUT: Square Wave/Output Driver. Programmable output that can be used for generating a square wave or as a simple output pin.
6. VBAT: Backup Battery Input. Provides power to the clock when the main supply is unavailable, maintaining timekeeping.
7. NC: No Connect. These pins are typically not connected internally and should be left unconnected on the board.
8. NC: No Connect. Another pin to be left unconnected.
These pins enable the DS1338Z-33+ to maintain accurate timekeeping and allow interfacing with other devices over the I²C bus.
