DS1236 FUNCTIONAL BLOCK DIAGRAM Figure 1
If the IN pin is connected to V CCO , the NMI output will pulse low as V CC decays to V CCTP in the NMOS
mode (RC=0). In the CMOS mode (RC=V CCO ) the power-down of V CC out-of-tolerance at V CCTP will not
produce a pulse on the NMI pin. Given that any NMI pulse has been completed by the time V CC decays
to V CCTP , the NMI pin will remain high. The NMI voltage will follow V CC down until V CC decays to
V BAT . Once V CC decays to V BAT , the NMI pin will either remain at V OHL or enter tri-state mode as
determined by the RC pin (see “Reset Control” section).
MEMORY BACKUP
The DS1236 provides all of the necessary functions required to battery back a static RAM. First, a switch
is provided to direct SRAM power from the incoming 5-volt supply (V CC ) or from an external battery
(V BAT ), whichever is greater. This switched supply (V CCO ) can also be used to battery back a CMOS
microprocessor. For more information about nonvolatile processor applications, review the “Reset
Control” and “Wake Control” sections. Second, the same power-fail detection described in the power
monitor section is used to hold the chip enable output ( CEO ) to within 0.3 volts of V CC or to within 0.7
volts of V BAT . This write protection mechanism occurs as V CC falls below V CCTP as specified. If CEI is
