In-System Sector Protect/Unprotect Algorithms

Sector Protect:

Write 60h to sector

address with

A6 = 0, A1 = 1,

A0 = 0

Set up sector

address

Wait 150 µs

Verify Sector

Protect: Write 40h

to sector address

with A6 = 0,

A1 = 1, A0 = 0

Read from

sector address

with A6 = 0,

A1 = 1, A0 = 0

START

PLSCNT = 1

RESET# = VID

Wait 1

µs

First Write

Cycle = 60h?

Data = 01h?

Remove VID

from RESET#

Write reset

command

Sector Protect

complete

Yes

No

PLSCNT

= 25?

Yes

Device failed

Increment

PLSCNT

Temporary Sector

Unprotect Mode

No

Sector Unprotect:

Write 60h to sector

address with

A6 = 1, A1 = 1,

A0 = 0

Set up first sector

address

Wait 15 ms

Verify Sector

Unprotect: Write

40h to sector

address with

A6 = 1, A1 = 1,

A0 = 0

Read from

sector address

with A6 = 1,

A1 = 1, A0 = 0

START

PLSCNT = 1

RESET# = VID

Wait 1

µs

Data = 00h?

Last sector

verified?

Remove VID

from RESET#

Write reset

command

Sector Unprotect

complete

Yes

No

PLSCNT

= 1000?

Yes

Device failed

Increment

PLSCNT

Temporary Sector

Unprotect Mode

No

All sectors

protected?

Yes

Protect all sectors:

The indicated portion

of the sector protect

algorithm must be

performed for all

unprotected sectors

prior to issuing the

first sector

unprotect address

Set up

next sector

address

No

Yes

No

Yes

No

Yes

No

Sector Protect

Algorithm

Sector Unprotect

Algorithm

First Write

Cycle = 60h?

Protect another

sector?

Reset

PLSCNT = 1
