M48Z58Y

5V, 64Kbit (8Kbit x 8) ZEROPOWER ® SRAM

Features

■ Integrated, ultra low power SRAM, power-fail

control circuit, and battery

■ READ cycle time equals WRITE cycle time

■ Automatic power-fail chip deselect and WRITE

protection

■ WRITE protect voltages:

(VPFD = Power-fail deselect voltage)

– M48Z58: VCC = 4.75 to 5.5V

4.5V ≤ VPFD ≤ 4.75V

– M48Z58Y: VCC = 4.5 to 5.5V

4.2V ≤ VPFD ≤ 4.5V

■ Self-contained battery in the CAPHAT™ DIP

package

■ Packaging includes a 28-lead SOIC and

SNAPHAT® top (to be ordered separately)

■ SOIC package provides direct connection for a

SNAPHAT top which contains the battery

■ Pin and function compatible with JEDEC

standard 8Kbit x 8 SRAMs

■ RoHS compliant

– Lead-free second level interconnect
