DS1554P-70规格书详情
DESCRIPTION
The DS1554 is a full function, year 2000-compliant (Y2KC), real-time clock/calendar (RTC) with a RTC alarm, watchdog timer, power-on reset, battery monitor, and 32k x 8 non-volatile static RAM. User access to all registers within the DS1554 is accomplished with a bytewide interface as shown in Figure 1. The RTC Registers contain century, year, month, date, day, hours, minutes, and seconds data in 24-hour BCD format. Corrections for day of month and leap year are made automatically.
FEATURES
■ Integrated NV SRAM, real time clock, crystal, power-fail control circuit and lithium energy source
■ Clock registers are accessed identically to the static RAM; these registers are resident in the 16 top RAM locations
■ Century byte register; i.e., Y2K complaint
■ Totally nonvolatile with over 10 years of operation in the absence of power
■ Precision power-on reset
■ Programmable watchdog timer and RTC alarm
■ BCD coded year, month, date, day, hours, minutes, and seconds with automatic leap year compensation valid up to the year 2100
■ Battery voltage level indicator flag
■ Power-fail write protection allows for ±10 VCC power supply tolerance
■ Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time
