The RX-8581JE:B0 is a Real Time Clock (RTC) from Seiko Epson that provides a low-cost, low-power solution for accurate timekeeping applications. The device features an on-board programmable timer, alarm and calendar, as well as time/date transfers between multiple time zones with redundancy features.

The RX-8581JE:B0 is suitable for a broad range of applications such as embedded systems, automotive, telecommunications and datacenter applications. It is a single-chip device that requires no external components other than a small external crystal and backup power. This makes it an ideal solution for applications that require small form factor, low power and long battery life.

The RX-8581JE:B0 is a conventional quartz oscillator-based RTC. It operates from a small external quartz crystal resonator and uses a 32.768KHz frequency as its time base. The chip includes a 32-bit RTC control IC, built-in programmable timer and 14-bit counter, and an on-chip power supply. It also includes an alarm, calendar and a time/date transfer function.

The chip is designed to maintain an accurate timekeeping reference for system applications, even in the event of power failure. It includes multiple statuses such as Date Count EN, Alarm1EN and Alarm2EN, which indicate its active or inactive state. The status of the chip can be read or programmed by means of several I/O ports.

The RX-8581JE:B0 is capable of time/date transfer between multiple time zones with redundancy features. It can be used to transfer data between multiple time zones with different time formats. The time/date transfers are done with a serial port and a simple command structure. The on-chip power supply enables the chip to operate even in the event of power failure.

The RX-8581JE:B0 is a reliable, low-cost and low-power solution for accurate timekeeping applications. Its numerous features such as alarm, calendar and time/date transfer make it an ideal solution for embedded systems, automotive, telecommunications and datacenter applications. Its on-chip power supply ensures that the chip operates even in the event of power failure. Its small size and low power requirements make it a perfect fit for applications that require small form factors and long battery life.
