Notes:
1. READ DATA BYTES at HIGHER SPEED, PAGE PROGRAM, SECTOR ERASE, BLOCK ERASE,
DEEP POWER-DOWN, READ ELECTRONIC SIGNATURE, WRITE ENABLE/DISABLE, READ ID,
READ/WRITE STATUS REGISTER
2. The tCH and tCL signals must be greater than or equal to 1/fC.
3. The tCLCH, tCHCL, tSHQZ, tHHQX, tHLQZ, tDP, tRES1, and tRES2 signal values are guaranteed by
characterization, not 100% tested in production.
4. The tCLCH and tCHCLsignals clock rise and fall time values are expressed as a slew-rate.
5. The tWHSL and tSHWLsignals are only applicable as a constraint for a WRITE STATUS REGIS-
TER command when SRWD bit is set at 1.
