Explanatory notes for Table 2

"X" signifies "don't care" (that is to say, any value may be input).

The "h" following each code indicates that the number given is in hexadecimal notation.

Addresses A23 to A20 for all commands are "Don't care".

In order for commands other than the read command to be recognized, CS must rise after all the bus cycle input.

*1. MD: mode register data. Various operation methods of the HD_READ mode such as the operation frequencies

and the clock latency. Please refer to Table 3 for details.

*2: "PD" stands for page program data. Any amount of data from 1 to 256 bytes in 1-byte unit is input.

*3: Of the two silicon ID commands, it is for the command with the 9Fh setting that the manufacturer code 62h is first

output. For as long as the clock input is continued, 20h of the device code is output continuously, followed by the

repeated output of 62h and 20h.

*4: Read ID2 (ABh) A7 to A1 are don't care. A read cycle from address A0=‘0’ outputs the manufacture code

(SANYO: 62h). A read cycle at address A0=‘1’ outputs the device code (20h).
