FEATURES SUMMARY

■

INTEGRATED, ULTRA LOW POWER SRAM,

REAL TIME CLOCK, POWER-FAIL

CONTROL CIRCUIT, BATTERY, AND

CRYSTAL

■

YEAR 2000 COMPLIANT

■

BCD CODED CENTURY, YEAR, MONTH,

DAY, DATE, HOURS, MINUTES, AND

SECONDS

■

BATTERY LOW WARNING FLAG

■

AUTOMATIC POWER-FAIL CHIP

DESELECT AND WRITE PROTECTION

■

TWO WRITE PROTECT VOLTAGES:

(VPFD = Power-fail Deselect Voltage)

–

M48T129Y: VCC = 4.5 to 5.5V

4.2V

≤ VPFD ≤ 4.5V

–

M48T129V: VCC = 3.0 to 3.6V

2.7V

≤ VPFD ≤ 3.0V

■

CONVENTIONAL SRAM OPERATION;

UNLIMITED WRITE CYCLES

■

SOFTWARE CONTROLLED CLOCK

CALIBRATION FOR HIGH ACCURACY

APPLICATIONS

■

10 YEARS OF DATA RETENTION AND

CLOCK OPERATION IN THE ABSENCE OF

POWER

■

SELF CONTAINED BATTERY AND

CRYSTAL IN DIP PACKAGE

■

MICROPROCESSOR POWER-ON RESET

(Valid even during battery back-up mode)

■

PROGRAMMABLE ALARM OUTPUT

ACTIVE IN BATTERY BACK-UP MODE

■

SOIC PACKAGE PROVIDES DIRECT

CONNECTION FOR A SNAPHAT TOP

WHICH CONTAINS THE BATTERY AND

CRYSTAL

■

SNAPHAT HOUSING (BATTERY/CRYSTAL)

IS REPLACEABLE

■

EQUIVALENT SURFACE-MOUNT (SMT)

SOLUTION REQUIRES A 44-PIN M48T201Y/

V AND A STAND-ALONE 128K x8 LPSRAM

(SNAPHAT® Top to be ordered separately)
