Remark
Preliminary
0.1
1. Changed Input / Output Capacitance
- Input / Output Capacitance (Max.) : 20 pF --> 30pF
- Input Capacitance (Max.) : 20 pF --> 30pF
1. Changed SE pin description
- SE is recommended to coupled to GND or Vcc and should not be
toggled during reading or programming.
1. Changed don鈥?care mode in address cycles
t
- *X can be "High" or "Low" => *L must be set to "Low"
2. Explain how pointer operation works in detail.
3. 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.
4. Updated operation for tRST timing
- If reset command(FFh) is written at Ready state, the device goes into
Busy for maximum 5us.
