M41ST85Y, M41ST85W
Power-on Reset
The M41ST85Y/W continuously monitors VCC.
When VCC falls to the power fail detect trip point,
the RST pulls low (open drain) and remains low on
power-up for tREC after VCC passes VPFD. The
RST pin is an open drain output and an appropri-
ate pull-up resistor should be chosen to control
rise time.
Reset Inputs (RSTIN1 & RSTIN2)
The M41ST85Y/W provides two independent in-
puts which can generate an output reset. The du-
ration and function of these resets is identical to a
reset generated by a power cycle. Table 6 and Fig-
ure 16 illustrate the AC reset characteristics of this
function. Pulses shorter than tR1 and tR2 will not
generate a reset condition. RSTIN1 and RSTIN2
are each internally pulled up to VCC through a
100k
resistor.

Table 6. Reset AC Characteristics
Note: 1. Pulse width less than 50ns will result in no RESET (for noise immunity).
2. Pulse width less than 20ms will result in no RESET (for noise immunity).
3. CL = 5pF (see Figure 19, page 23).
