SST25WF040B-40I/SN Memory by Microchip Technology
4Mb 1.65-1.95V SPI Serial Flash
| Status: | Active |
|---|---|
| Series: | SST25WF040B |
| RoHS: | Compliant |
This Serial Flash significantly improve performance and reliability, while lowering power consumption. The device writes (Program or Erase) with a single power supply of 1.65-1.95V. The total energy consumed is a function of the applied voltage, current, and time of application. Since for any given voltage range, the SuperFlash technology uses less current to program and has a shorter erase time, the total energy consumed during any Erase or Program operation is less than alternative flash memory technologies.
