Working Principle

The KR3225Y32768EAW30TAA RTC works by keeping track of the time with its built-in oscillator, which keeps a steady frequency of 32.768kHz, which is then regulated by the external crystal to keep a very precise frequency. The internal oscillator counts the approximately 32,768 cycles of the frequency, operating at 1Hz, while the external temperature-compensating crystal ensures an extremely accurate reliability. The frequency accuracy of this device is ±3ppm +2.5Hz, up to 20ppm. The device also offers a timer/alarm function with a 1-second resolution and memory backup operations.

The device is easily programmable for low-power operation and is capable of setting the second, hour, minute, month and day. This device also offers extended temperature range and an accurate time setting, temperature compensation feature and on-chip EEPROM voltage retention. In addition, the device supports enabling an internal 32.768kHz oscillator, powered by an on-chip battery, ensuring precise timekeeping and automatically resetting when there is a power failure.

The KR3225Y32768EAW30TAA RTC is an excellent choice for precise timekeeping, offering superior accuracy and extended temperature range. Its features, low power and easy programming make it an ideal solution for a vast range of applications. This device is highly recommended for applications requiring precise clock synchronization, accurate timekeeping and providing time information within systems.
