M48Z512AY General Description
With valid VCC applied, the M48Z512A/Y/V operates as a conventional BYTEWIDETM static RAM. Should the supply voltage decay, the RAM will automatically power-fail deselect, write protecting itself tWP after VCC falls below VPFD. All outputs become high impedance, and all inputs are treated as "don't care."
If power fail detection occurs during a valid access, the memory cycle continues to completion. If the memory cycle fails to terminate within the time tWP, write protection takes place. When VCC drops below VSO, the control circuit switches power to the internal energy source which preserves data.
The internal coin cell will maintain data in the M48Z512A/Y/V after the initial application of VCC for an accumulated period of at least 10 years when VCC is less than VSO. As system power returns and VCC rises above VSO, the battery is disconnected, and the power supply is switched to external VCC. Write protection continues for tER after VCC reaches VPFD to allow for processor stabilization. After tER, normal RAM operation can resume.
For more information on Battery Storage Life refer to the Application Note AN1012.
M48Z512AY Maximum Ratings
Stressing the device above the rating listed in the "Absolute Maximum Ratings" table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents.
