■
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
