Datasheet

Order Number: 306666, Revision: 001

To read data from the device (other than an erase-suspended block), the Read Array command must

be issued. During Erase Suspend, a Program command can be issued to any block other than the

erase-suspended block. Block erase cannot resume until program operations initiated during erase

suspend complete. Read Array, Read Status Register, Read Device Identifier, CFI Query, and Erase

Resume are valid commands during Erase Suspend. Additionally, Clear Status Register, Program,

Program Suspend, Block Lock, Block Unlock, and Block Lock-Down are valid commands during

Erase Suspend.

During an erase suspend, deasserting CE# places the device in standby, reducing active current.

VPP must remain at a valid level, and WP# must remain unchanged while in erase suspend. If

RST# is asserted, the device is reset.

12.3

Erase Resume

The Erase Resume command instructs the device to continue erasing, and automatically clears

status register bits SR[7,6]. This command can be written to any address. If status register error bits

are set, the Status Register should be cleared before issuing the next instruction. RST# must remain

deasserted (see Figure 41, “Program Suspend/Resume Flowchart” on page 86).

12.4

Erase Protection

When VPP = VIL, absolute hardware erase protection is provided for all device blocks. If VPP is

below VPPLK, erase operations halt and SR[3] is set indicating a VPP-level error.
