Power-on Reset
The M48T201Y/V 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 to VCC should be chosen to
control rise time.
Reset Inputs (RSTIN1 & RSTIN2)
The M48T201Y/V 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. Figure 12 and
Table 13 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 13. Reset AC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = 0 to 70°C or –40 to 85°C; VCC = 4.5 to 5.5V or 3.0 to 3.6V (except where noted).
3. tR1HRZ or tR2HRZ = 20ms for industrial temperature Grade 6 device.
