64 Megabit CMOS 3.0 Volt Flash Memory with 50MHz SPI (Serial Peripheral Interface) Bus

Spansion Inc. 

Data Sheet (Preliminary)

No Write Status Register, program, or erase command should be sent to the device until VCC rises to the VCC

min, plus a delay of tPU. At power-up, the device is in standby mode (not Deep Power Down mode) and the

WEL bit is reset (0).

Each device in the host system should have the VCC rail decoupled by a suitable capacitor close to the

package pins (this capacitor is generally of the order of 0.1 µF), as a precaution to stabilizing the VCC feed.

When VCC drops from the operating voltage to below the minimum VCC threshold at power-down, all

operations are disabled and the device does not respond to any commands. Note that data corruption may

result if a power-down occurs while a Write Register, program, or erase operation is in progress.

11. Initial Delivery State

The device is delivered with all bits set to 1 (each byte contains FFh) upon initial factory shipment. The Status

Register contains 00h (all Status Register bits are 0).

12. Absolute Maximum Ratings

Do not stress the device beyond the ratings listed in this section, or serious, permanent damage to the device

may result. These are stress ratings only and device operation at these or any other conditions beyond those

indicated in this section and in the Operating Ranges section of this document is not implied. Device

operation for extended periods at the limits listed in this section may affect device reliability.
