M48Z128
M48Z128Y, M48Z128V
5.0 V or 3.3 V, 1 Mbit (128 Kbit x 8) ZEROPOWER^® SRAM
Features
■ Integrated, ultra low power SRAM, power-fail
control circuit, and battery
■ Conventional SRAM operation; unlimited
WRITE cycles
■ 10 years of data retention in the absence of
power
■ Battery internally isolated until power is first
applied
■ Automatic power-fail chip deselect and WRITE
protection
■ WRITE protect voltages:
(V_PFD = power-fail deselect voltage)
– M48Z128: V_CC = 4.75 to 5.5 V
4.5 V ≤ V_PFD ≤ 4.75 V
– M48Z128Y: V_CC = 4.5 to 5.5 V
4.2 V ≤ V_PFD ≤ 4.5 V
– M48Z128V: V_CC = 3.0 to 3.6 V
2.8 V ≤ V_PFD ≤ 3.0 V
