M41ST95Y*, M41ST95W
Power-on Reset
The M41ST95Y/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 (max).
The RST pin is an open drain output and an appro-
priate pull-up resistor should be chosen to control
rise time.
Reset Input (RSTIN1 and RSTIN2)
The M41ST95Y/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 7 and Fig-
ure 16 illustrate the AC reset characteristics of this
function. Pulses shorter than tRLRH1 and tRLRH2
will not generate a reset condition. RSTIN1 and
RSTIN2 are each internally pulled up to VCC
through a 100k
resistor.

Note: 1. Open Drain Output
Table 7. Reset AC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 4.5 to 5.5V or 2.7 to 3.6V (except where noted).
2. Pulse width less than 50ns will result in no RESET (for noise immunity).
3. Pulse width less than 20ms will result in no RESET (for noise immunity).
4. Programmable (see Table 8., page 23)
5. After crystal oscillator has started
