M41ST95Y*, M41ST95W
Power-on Reset
The M41ST95Y/W continuously monitors V
CC
.
When V
CC
falls to the power fail detect trip point,
the RST pulls low (open drain) and remains low on
power-up for t
REC
after V
CC
passes V
PFD
(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 t
RLRH1
and t
RLRH2
will not generate a reset condition. RSTIN1
and
RSTIN2 are each internally pulled up to V
CC
through a 100k
resistor.

Note: 1. Valid for Ambient Operating Temperature: T
A
= –40 to 85°C; V
CC
= 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).
