LHF00L14 10 9. following the clear block lock bit command, block which is not locked-down is unlocked when wp#/acc is v il . when wp#/acc is v ih , lock-down bit is disabled and the selected block is unlocked regardless of lock-down configuration. 10. commands other than those shown above are reserved by sharp for future device implementations and should not be used. rev. 2.45
LHF00L14 11 notes: 1. dq 0 =1: a block is locked; dq 0 =0: a block is unlocked. dq 1 =1: a block is locked-down; dq 1 =0: a block is not locked-down. 2. erase and program are general terms, respectively, to express: block erase, full chip erase and program operations. 3. at power-up or device reset, all blocks default to locked state and are not locked-down, that is, [001] (wp#/acc=0) or [101] (wp#/acc=1), regardless of the states before power-off or reset operation. 4. when wp#/acc is driven to v il in [110] state, the state changes to [011] and the blocks are automatically locked. 5. otp (one time program) block has the lock function which is different from those described above. notes: 1. "set lock" means set block lock bit command, "clear lock" means clear block lock bit command and "set lock-down" means set block lock-down bit command. 2. when the set block lock-down bit command is written to the unlocked block (dq 0 =0), the corresponding block is locked-down and automatically locked at the same time. 3. "no change" means that the state remains unchanged after the command written. 4. in this state transitions table, assumes that wp#/acc is not changed and fixed v il or v ih . table 5. functions of block lock (5) and block lock-down current state erase/program allowed (2) state wp#/acc dq 1 (1) dq 0 (1) state name [000] 0 0 0 unlocked yes [001] (3) 001locked no [011] 0 1 1 locked-down no [100] 1 0 0 unlocked yes [101] (3) 101locked no [110] (4) 1 1 0 lock-down disable yes [111] 1 1 1 lock-down disable no table 6. block locking state transitions upon command write (4) current state result after lock command written (next state) state wp#/acc dq 1 dq 0 set lock (1) clear lock (1) set lock-down (1) [000] 0 0 0 [001] no change [011] (2) [001] 0 0 1 no change (3) [000] [011] [011] 0 1 1 no change no change no change [100] 1 0 0 [101] no change [111] (2) [101] 1 0 1 no change [100] [111] [110] 1 1 0 [111] no change [111] (2) [111] 1 1 1 no change [110] no change rev. 2.45
LHF00L14 12 notes: 1. "wp#/acc=0 1" means that wp#/acc is driven to v ih and "wp#/acc=1 0" means that wp#/acc is driven to v il . 2. state transition from the current state [011] to the next state depends on the previous state. 3. when wp#/acc is driven to v il in [110] state, the state changes to [011] and the blocks are automatically locked. 4. in this state transitions table, assumes that lock configuration commands are not written in previous, current and next state. table 7. block locking state transitions upon wp#/acc transition (4) previous state current state result after wp#/acc transition (next state) state wp#/acc dq 1 dq 0 wp#/acc=0 1 (1) wp#/acc=1 0 (1) - [000] 0 0 0 [100] - - [001] 0 0 1 [101] - [110] (2) [011] 0 1 1 [110] - other than [110] (2) [111] - - [100] 1 0 0 - [000] - [101] 1 0 1 - [001] -[110]110 - [011] (3) - [111] 1 1 1 - [011] rev. 2.45

LHF00L14 17 notes: 1. all currents are in rms unless otherwise noted. typical values are the reference values at v cc =3.0v and t a =+25 c unless v cc is specified. 2. i ccws and i cces are specified with the device de-selected. if read or program is executed while in block erase suspend mode, the device?s current draw is the sum of i cces and i ccr or i ccw . if read is executed while in program suspend mode, the device?s current draw is the sum of i ccws and i ccr . 3. the automatic power savings (aps) feature automatically places the device in power save mode after read cycle completion. standard address access timings (t avqv ) provide new data when addresses are changed. 4. sampled, not 100% tested. 5. applying 12.0v0.3v to wp#/acc provides fast erasing or fast programming mode. in this mode, wp#/acc is power supply pin and supplies the memory cell current for block erasing and programming. use similar power supply trace widths and layout considerations given to the v cc power bus. applying 12.0v0.3v to wp#/acc during erase/program can only be done for a maximum of 1,000 cycles on each block. wp#/acc may be connected to 12.0v0.3v for a total of 80 hours maximum. 6. for all pins other than those shown in test conditions, input level is v cc or gnd. 7. includes ry/by#. v il input low voltage 5 -0.4 0.4 v v ih input high voltage 4 2.4 v cc + 0.4 v v ol output low voltage 4,7 0.2 v v cc =v cc min., i ol =100 a v oh output high voltage 4 v cc -0.2 v v cc =v cc min., i oh =-100a v acch wp#/acc during block erase, full chip erase, program or otp program operations 5 11.7 12.0 12.3 v v lko v cc lockout voltage 1.5 v v cc =2.7v-3.6v symbol parameter notes min. typ. max. unit test conditions dc characteristics (continued) rev. 2.45
