M48Z58
M48Z58Y
5 V, 64 Kbit (8 Kbit x 8) ZEROPOWER® SRAM
Features
â Integrated, ultra low power SRAM, power-fail
control circuit, and battery
â READ cycle time equals WRITE cycle time
â Automatic power-fail chip deselect and WRITE
protection
â WRITE protect voltages:
(VPFD = Power-fail deselect voltage)
â M48Z58: VCC = 4.75 to 5.5 V
4.5 V ⤠VPFD ⤠4.75 V
â M48Z58Y: VCC = 4.5 to 5.5 V
4.2 V ⤠VPFD ⤠4.5 V
â Self-contained battery in the CAPHAT⢠DIP
package
â Packaging includes a 28-lead SOIC and
SNAPHAT® top (to be ordered separately)
â SOIC package provides direct connection for a
SNAPHAT® top which contains the battery
â Pin and function compatible with JEDEC
standard 8 Kbit x 8 SRAMs
â RoHS compliant
â Lead-free second level interconnect
