DS1643-100 is a serial real-time clock that can be used in a wide variety of applications. This clock is ideal for embedded systems where accurate timekeeping is important. The DS1643-100 features a three-channel direct-memory-access (DMA) controller and a battery-backup feature, enabling designers to maximize data-collection accuracy while minimizing power consumption. It is available in two package sizes: a 28-pin DIP package and a 16-pin SOIC package.

The DS1643-100 is one of the most versatile real-time clocks on the market today. It provides a wide range of features, including three-channel DMA controller, programmable clock output, battery-backup feature, watchdog timer, interrupt controller and a programmable clock divider. The clock can operate from a wide range of battery voltages and temperatures and can maintain time-keeping accuracy over a wide range of environmental conditions. The DS1643-100 can be used in a variety of applications, including automotive audio systems, home automation, industrial control systems, computer gaming systems and data acquisition systems.

The DS1643-100 uses a 32-bit RTC crystal oscillator to accurately keep track of time. The crystal oscillator is driven by a programmable output frequency that can be set anywhere between 1 Hz and 32 KHz. The RTC is also programmable, allowing users to adjust the periodic alert or interrupt timing to suit their needs. In addition, the RTC allows for time-stamping and alarm functions.

The DS1643-100 also features a battery-backup feature, which provides an uninterrupted time-keeping function even when power is lost. With the battery-backup feature, the DS1643-100 will continue to operate according to the programmed output frequency, even when the power supply is disconnected. This makes the DS1643-100 an ideal choice for embedded systems where reliable timekeeping is important.

The DS1643-100 also features a three-channel DMA controller that can support up to three data-collection modules simultaneously. This allows the DS1643-100 to perform multiple data-collection tasks simultaneously, such as collecting data from different sensors. The DS1643-100 also includes a watchdog timer and an interrupt controller, which can be used to monitor system activity and provide an alert when certain conditions are met. The interrupt controller can also be used to trigger other peripherals, such as power switching devices or serial interfaces.

The DS1643-100 is a highly featured real-time clock that can be used in a variety of applications. With its small size and versatile features, the DS1643-100 makes an excellent choice for many embedded systems. It is available in two packages: a 28-pin DIP package and a 16-pin SOIC package, making it easy to integrate into existing designs. With its combination of versatile features and reliable time-keeping, the DS1643-100 is an ideal choice for many real-time clock applications.
