Electrical Characteristics

A.7.1.1 Erase Verify All Blocks (Blank Check) (FCMD=0x01)

The time required to perform a blank check on all blocks is dependent on the location of the ï¬rst non-blank

word starting at relative address zero. It takes one bus cycle per phrase to verify plus a setup of the

command. Assuming that no non-blank location is found, then the time to erase verify all blocks is given

by:

FTMRG240K2, FTMRG192K2:

tcheck = 64400 â f--N----V---M-1---B---U---S-

FTMRG128K1,FTMRG96K1:

tcheck = 33600 â f--N----V---M-1---B---U---S-

FTMRG64K1, FTMRG48K1:

tcheck = 18000 â f--N----V---M-1---B---U---S-

FTMRG32K1,FTMRG16K1:

tcheck = 9300 â f--N----V---M-1---B---U---S-

A.7.1.2 Erase Verify Block (Blank Check) (FCMD=0x02)

The time required to perform a blank check is dependent on the location of the ï¬rst non-blank word starting

at relative address zero. It takes one bus cycle per phrase to verify plus a setup of the command.

Assuming that no non-blank location is found, then the time to erase verify a P-Flash block is given by:

FTMRG240K2, FTMRG192K2:

tpcheck = 62200 â -f-N----V---M-1---B---U---S-

FTMRG128K1, FTMRG96K1:

tpcheck = 33400 â -f-N----V---M-1---B---U---S-
