DESCRIPTION
The DS1743 is a full-function, year-2000-compliant (Y2KC), real-time clock/calendar (RTC) and 8k x 8
nonvolatile static RAM. User access to all registers within the DS1743 is accomplished with a bytewide
interface as shown in Figure 1. The RTC information and control bits reside in the eight uppermost RAM
locations. The RTC registers contain century, year, month, date, day, hours, minutes, and seconds data in
24-hour binary-coded decimal (BCD) format. Corrections for the day of the month and leap year are made
automatically. The RTC clock registers are double buffered to avoid access of incorrect data that can occur
during clock update cycles. The double-buffered system also prevents time loss as the timekeeping
countdown continues unabated by access to time register data. The DS1743 also contains its own power-
fail circuitry, which deselects the device when the VCC supply is in an out-of-tolerance condition. When
VCC is above VPF, the device is fully accessible. When VCC is below VPF, the internal CE signal is forced
high, preventing any access. When VCC rises above VPF, access remains inhibited for TREC, allowing time
for the system to stabilize. These features prevent loss of data from unpredictable system operation brought
on by low VCC as errant access and update cycles are avoided.
