M48Z2M1Y
M48Z2M1V
5V or 3.3V, 16 Mbit (2Mb x 8) ZEROPOWER^® SRAM
FEATURES SUMMARY
■ INTEGRATED, ULTRA LOW POWER SRAM,
POWER-FAIL CONTROL CIRCUIT, AND
BATTERIES
■ CONVENTIONAL SRAM OPERATION;
UNLIMITED WRITE CYCLES
■ 10 YEARS OF DATA RETENTION IN THE
ABSENCE OF POWER
■ AUTOMATIC POWER-FAIL CHIP
DESELECT AND WRITE PROTECTION
■ WRITE PROTECT VOLTAGES
(V_PFD = Power-fail Deselect Voltage):
– M48Z2M1Y: V_CC = 4.5 to 5.5V
4.2V ≤ V_PFD ≤ 4.5V
– M48Z2M1V: V_CC = 3.0 to 3.6V
2.8V ≤ V_PFD ≤ 3.0V
■ BATTERIES ARE INTERNALLY ISOLATED
UNTIL POWER IS APPLIED
■ PIN AND FUNCTION COMPATIBLE WITH
JEDEC STANDARD 2Mb x 8 SRAMs
