Table 2. Absolute Maximum Ratings (1)
Note: 1. Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational section
of this specification is not implied. Exposure to the absolute maximum rating conditions for extended periods of time may affect
reliability.
2. Soldering temperature not to exceed 260°C for 10 seconds (total thermal budget not to exceed 150°C for longer than 30 seconds).
CAUTION: Negative undershoots below –0.3V are not allowed on any pin while in the Battery Back-up mode.

Figure 3 illustrates the static memory array and the
quartz controlled clock oscillator. The clock loca-
tions contain the century, year, month, date, day,
hour, minute, and second in 24 hour BCD format.
Corrections for 28, 29 (leap year), 30, and 31 day
months are made automatically. The nine clock
bytes (7FFFFh-7FFF9h and 7FFF1h) are not the
actual clock counters, they are memory locations
consisting of BiPORT read/write memory cells
within the static RAM array.
