Legend:
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 write pulse.
SA = Address of the sector to be erased. The combination of A22, A21, A20, A19, A18, A17, A16, A15, A14, A13 and
A12 will uniquely select any sector.
BA = Bank Address. Address settled by A22, A21, A20, A19 will select Bank A, Bank B, Bank C and Bank D.
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 write pulse.
SGA = Sector group address to be protected.
WPH = (A7, A6, A5, A4, A3, A2, A1, A0) is (0, 0, 0, 0, 0, 0, 1, 0)
SD = Sector group protection verify data. Output 01h at protected sector group addresses and output
00h at unprotected sector group addresses.
HRA = Address of the HiddenROM area Word Mode : 000000h to 00007Fh
HRBA = Bank Address of the HiddenROM area (A22 = A21 = A20 = VIL)
RD (0) = Read Data bit. If protected, DQ0 = 1, if unprotected, DQ0 = 0
RD (1) = Read Data bit. If protected, DQ1 = 1, if unprotected, DQ1 = 0
OPBP = (A7, A6, A5, A4, A3, A2, A1, A0) is (0, 0, 0, 1, 1, 0, 1, 0)
PWA/PWD = Password Address/Password Data
PL = (A7, A6, A5, A4, A3, A2, A1, A0) is (0, 0, 0, 0, 1, 0, 1, 0)
SPML = (A7, A6, A5, A4, A3, A2, A1, A0) is (0, 0, 0, 1, 0, 0, 1, 0)
WP = (A7, A6, A5, A4, A3, A2, A1, A0) is (0, 0, 0, 0, 0, 0, 1, 0)
*1: This command is valid during Fast Mode.
*2: This command is valid while RESET = VID.
*3: This command is valid during HiddenROM mode.
*4: The data “00h” is also acceptable.
Notes : • Address bits A22 to A11 = X = “H” or “L” for all address commands except for
PA, SA, BA, SGA, OPBP, PWA, PL, SPML, WP, WPH.
• Bus operations are defined in this document.
• The system should generate the following address patterns:
Word Mode : 555h or 2AAh to addresses A10 to A0
• Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
