Description
The M48Z35/Y ZEROPOWER® RAM is a 32 K x 8, non-volatile static RAM that integrates powerfail deselect circuitry and battery control logic on a single die.
The monolithic chip is available in two special packages to provide a highly integrated battery-backed memory solution.
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).
- M48Z35: VCC = 4.75 to 5.5 V;
4.5 V ≤ VPFD ≤ 4.75 V.
- M48Z35Y: 4.5 to 5.5 V;
4.2 V ≤ VPFD ≤ 4.5 V.
- Self-contained battery in the CAPHAT™ DIP
package.
- Packaging includes a 28-lead SOIC and
SNAPHA.
