Not For New Design

Features

■ 3.0V, 3.3V, or 5V operating voltage

■ Real-time clock keeps track of

tenths/hundredths of seconds, seconds,

minutes, hours, days, date of the month,

months, and years

■ Automatic leap year correction valid up to 2100

■ Automatic switch-over and deselect circuitry

■ Choice of power-fail deselect voltages:

SO16 (MQ)

= power-fail deselect voltage)

PFD

2.80V ≤ V

≤ 2.97V

PFD

– M41T315W: V = 2.7 to 3.3V

SNAPHAT (SH)

battery & crystal

2.60V ≤ V

≤ 2.70V

PFD

■ No address space required to communicate

with RTC

■ Provides nonvolatile supervisor functions for

battery backup of SRAM

■ Full 10% V operating range

■ Industrial operating temperature range (–40 to

+85°C)

■ Ultra-low battery supply current of 500nA (max)

■ Optional packaging includes A 28-lead SOIC

and SNAPHAT top (to be ordered separately)

SOH28 (MH)

■ SNAPHAT package provides direct connection

for a snaphat top, which contains the battery

and crystal

■ RoHS compliant

– Lead-free second level interconnect
