Notes: 1. Address bits A11 to A20 = X = “H” or “L” for all address commands except or Program Address (PA) and
Sector Address (SA).
2. Bus operations are defined in Table 2.
3. RA =Address of the memory location to be read.
PA =Address of the memory location to be programmed. Addresses are latched on the falling edge of
the WE pulse.
SA =Address of the sector to be erased. The combination of A20, A19, A18, A17, A16, A15, A14, and A13 will
uniquely select any sector.
4. RD =Data read from location RA during read operation.
PD =Data to be programmed at location PA. Data is latched on the rising edge of WE.
5. Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
Command Definitions
Device operations are selected by writing specific address and data sequences into the command register.
Writing incorrect address and data values or writing them in the improper sequence will reset the devices to
read mode. Table 6 defines the valid register command sequences. Note that the Erase Suspend (B0H) and
Erase Resume (30H) commands are valid only while the sector Erase operation is in progress. Moreover, both
Read/Reset commands are functionally equivalent, resetting the device to the read mode. Please note that
commands are always written at DQ0 to DQ7 bits are ignored.
