DS1558Y

The DS1558Y is one of the many Real Time Clocks (RTCs) available for use in electronics applications. This device, produced by Dallas Semiconductor, is a low power, battery backed SRAM that includes all of the essential functions of a standard RTC. It includes a crystal oscillator, 16-bit timer/counter, and battery options. With its integration into a single chip, the DS1558Y can provide a variety of applications in the field of timing, frequency, clock and timing generation, industrial and automotive data acquisition, calendar timekeeping, and control systems.

The DS1558Y works on a battery backup system in which it is powered by the primary battery and a smaller secondary battery which is used to maintain clock parameters and RAM data during periods of power failure. The RTC clock accuracy is 0.25% and the RTC has low static & dynamic power consumption of 22uA & 50uA respectively. It also features an automatic power fail warning and detection.

The DS1558Y offers many features which make it ideal for a variety of applications. It has two 16-bit timers/counters for frequency and timing generation, a 32-bit battery-backup real-time clock, an adjustable accuracy crystal oscillator, and a high-speed read/write SRAM memory that is accessed at 20MHz. These features make the DS1558Y suitable for applications such as frequency and timing generation, calendar timekeeping, industrial and automotive data acquisition, and control systems.

The DS1558Y\'s high-speed read and write SRAM memory can be accessed at 20MHz rates and can store up to 512 bytes of user data. This data can be used for a variety of applications such as storing configurable parameters for system operation, and for performing various software operations. The device also has complete calendar timekeeping capabilities for applications such as recording and tracking time-stamped events.

The DS1558Y\'s adjustable accuracy crystal oscillator provides an extremely accurate reference signal for frequency and timing generation. The device can also be synchronized with external clocks up to 40MHz. This means that the device can be incorporated into systems requiring synchronized clocks, such as cellular switches and communication systems.
