SA8025A（SA8025ADK） SSOP20 IMAGE FOR REF

The SA8025A, also known as the SA8025ADK, is a highly integrated real-time clock (RTC) IC housed in a compact SSOP20 package. This device is engineered for applications requiring precise timekeeping, calendar functionality, and low power consumption. It's an ideal solution for embedded systems, portable devices, and any application where maintaining accurate time is critical even when the main power source is unavailable. The SA8025A features a built-in 32.768 kHz crystal oscillator, which provides a stable and accurate time base. This eliminates the need for an external crystal, simplifying the design and reducing the overall board space. The RTC core includes registers for seconds, minutes, hours, day of the week, date, month, and year, with automatic leap year compensation.

The device communicates with the host microcontroller via a simple I2C serial interface, making it easy to integrate into existing systems. Its low power design ensures long battery life when operating in backup mode, typically using a small coin cell battery. The SA8025A also includes programmable alarm functions, allowing the system to wake up at specific times or intervals. This feature is particularly useful for power-sensitive applications where the system needs to be in a low-power sleep state most of the time. Additional features include a programmable square wave output, which can be used as a clock source for other devices in the system, and a power-on reset function, which ensures that the RTC starts in a known state. The SSOP20 package provides a small footprint and is suitable for surface mount assembly.

Key applications for the SA8025A include industrial control systems, consumer electronics, point-of-sale terminals, and automotive applications. Its robust design and wide operating temperature range make it suitable for use in harsh environments. The SA8025A offers a reliable and cost-effective solution for real-time clock functionality. Whether you're designing a new product or upgrading an existing one, the SA8025A provides the accuracy and features you need. Don't compromise on timekeeping accuracy. Add the SA8025A to your design today and ensure reliable and precise time management for your application.
