Information

History

1. Initial issue

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

2. Unified access timing parameter definition for multiple operating modes

- Changed AC characteristics (Before)

- AC characteristics (After)

. Deleted tCR,tRSTO, tCSTO and tREADID / Added tCEA
