Revision J

AT25FF321A

32-Mbit, 1.65 V - 3.6 V SPI Serial Flash Memory

with Multi-I/O Support

4.9.6 Terminate Command (F0h)

The Terminate (F0) command does not cause exit from DPD or UDPD modes. To exit DPD or UDPD mode still requires either

the ABh command, or resetting the device as described in the previous subsections.

4.9.7 Reset During Program and Erase Commands

The AT25FF321A device supports the following program and erase operations.

Program operations include:



Byte/Page Program (02h)



Sequential Program (AFh/ADh)



Dual Output Byte/Page Program (A2h)



Quad Output Byte/Page Program (32h)



Program Security Register (9Bh)

Erase operations include:



4 kB Block Erase (20h)



32 kB Block Erase (52h)



64 kB Block Erase (D8h)



Chip Erase (60h/C7h)

These commands are affected when resetting the device, as shown in Table 7. In this table, a ‘Y’ entry indicates that the device

is reset when that type of reset occurs during the corresponding command. A ‘N’ entry indicates that the operation is terminated,

but the device is not reset. For example, when the F0h command is executed during a program or erase operation, the operation

is halted, but the device is not reset.
