The X1226S8 is a real-time clock (RTC) designed for applications in the computer and consumer clock/timing markets. This high performance device is manufactured using an advanced CMOS process, and is designed to interface with an external real-time clock crystal oscillator in order to keep accurate time and date information. The device also features a battery backup input that allows it to retain the time and date information when not powered.

The X1226S8 provides applications with accurate date and time information, enabling them to be aware of the current date and time, even when the power is turned off. This is beneficial for applications such as security systems, which require an accurate timestamp to identify when an event occurred. The device also has an alarm feature, which can be used to alert an application when an alarm is triggered.

The X1226S8 is available in multiple package options, including a 28-pin QFN package, a 14-pin SOIC package, a 16-pin TSSOP package, and an 8-pin TSSOP package. It is designed to operate with an external 32.768 KHz real-time clock crystal oscillator. The device has an internal reference voltage of 2.5V, and can operate with a supply voltage between 1.8V and 5.5V.

The X1226S8 contains several features that ensure accurate real-time clock operation and high accuracy timekeeping over a wide range of operating temperatures and supply voltages. The device features an internal power-on reset circuit, which ensures that the device resets when power is cycled. This helps to prevent the clock from slowing down or losing accuracy over time. The device has an internal trimming capacitor, which helps to maintain accuracy by trimming the clock frequency to match the external crystal oscillator.

The X1226S8 also includes a number of flexible time and event control functions, including a time of day (24-hour) function, an event timer function, and an interrupt output. The time of day function can be used to generate an interrupt when the clock reaches a specified time. The event timer function can be used to generate an interrupt when a specified amount of time has elapsed. The interrupt output can be used to trigger a power-down sequence, or to indicate when a specified event has occurred.

The X1226S8 includes several power management features, including a low power-consumption mode, which can reduce power consumption to just 10 µA. The device can also support advanced battery saving features, such as automatically powering down to minimize battery drain. In addition, the X1226S8 has a power fail indicator that can be used to inform the application when the power is failing.

The X1226S8 real-time clock is a versatile device that can provide accurate timekeeping in a wide variety of applications, including security systems, network products, and industrial applications. Its small size and low power consumption make it an ideal choice for battery powered applications such as wearable devices. It is also easy to integrate, with minimal external components required for operation.
