Information

1. Renamed GND input (pin # 6) on behalf of SE (pin # 6)
- The SE input controls the access of the spare area. When SE is high,
the spare area is not accessible for reading or programming. SE is rec
ommended to be coupled to GND or Vcc and should not be toggled
during reading or programming.
=> Connect this input pin to GND or set to static low state unless the
sequential read mode excluding spare area is used.
2. Updated operation for tRST timing
- If reset command(FFh) is written at Ready state, the device goes into
Busy for maximum 5us.
1. Changed GND input (pin # 6) pin to N.C ( No Connection).
- The pin # 6 is don’t-cared regardless of external logic input level
and is fixed as low internally.
1. Changed plane address in Copy-Back Program
- A24 and A25 must be the same between source and target page
=> A14 and A15 must be the same between source and target page
1. Changed DC characteristics

History
1. Addition of new operation : Multi-Plane Copy-Back Program.
- Multi-Plane Copy-Back Program is extended operation of one-page
Copy-Back program.
=> After successive reading of multiple 528 byte data set at the source
planes, the above data are moved to internal page registers and same
procedure as Multi-Plane Page Programming is executed.
1.Powerup sequence is added
: Recovery time of minimum 1ms is required before internal circuit gets
ready for any command sequences

To clarify the meaning of parameter,
1. tRHZ is devide into tRHZ and tOH.(page 12)
- tRHZ : RE High to Output Hi-Z
- tOH : RE High to Output Hold
2. tCHZ is devide into tCHZ and tOH.(page 12)
- tCHZ : CE High to Output Hi-Z
- tOH : CE High to Output Hold
1. Pb-free Package is added.
K9F1208U0M-PCB0,PIB0
2. New definition of the number of invalid blocks is added.
(Minimum 1004 valid blocks are guaranteed for each contiguous 128Mb
memory space.)
3. Note is added.
(VIL can undershoot to -0.4V and VIH can overshoot to VCC +0.4V for
durations of 20 ns or less.)
