M48Z08
M48Z18
5 V, 64 Kbit (8 Kb x 8) ZEROPOWER^® SRAM
Features
■ Integrated, ultra low power SRAM and power-
fail control circuit
■ Unlimited WRITE cycles
■ READ cycle time equals WRITE cycle time
■ Automatic power-fail chip deselect and WRITE
protection
■ WRITE protect voltages
(V_PFD = power-fail deselect voltage):
– M48Z08: V_CC = 4.75 to 5.5 V
4.5 V ≤ V_PFD ≤ 4.75 V
– M48Z18: V_CC = 4.5 to 5.5 V
4.2 V ≤ V_PFD ≤ 4.5 V
■ Self-contained battery in the CAPHAT™ DIP
package
■ Pin and function compatible with JEDEC
standard 8 K x 8 SRAMs
■ RoHS compliant
– Lead-free second level interconnect
