(Continued)
*1
: Command combinations not described in “MBM29DL32TF/BF Command Definitions Table” are illegal.
*2
: Both of these reset commands are equivalent.
*3
: Erase Suspend and Erase Resume command are valid only during a sector erase operation.
*4
: This command is valid during Fast Mode.
*5 : The Reset from Fast mode command is required to return to the Read mode when the device is in Fast mode.
*6
: This command is valid while RESET
= VID (except during HiddenROM mode).
*7
: Sector Group Address (SGA) with (A6, A3, A2, A1, A0)
= (0, 0, 0, 1, 0)
*8
: The valid address are A6 to A0.
*9
: The HiddenROM Entry command is required prior to the HiddenROM programming.
*10 : This command is valid during HiddenROM mode.
*11 : The date “F0h” is also acceptable.
*12 : Fourth bus cycle becomes read cycle.
Notes:
Address bits A20 to A11 = X = “H” or “L” for all address commands except or Program Address (PA) , Sector
Address (SA) , Bank Address (BA) .
Bus operations are defined in “MBM29DL32TF/BF User Bus Operations Tables (BYTE = VIH and BYTE
= VIL)” (sDEVICE BUS OPERATION).
RA
= Address of the memory location to be read
IA
= Autoselect read address that sets both the bank address specified at (A20, A19, A18) and all the
other A6, A3, A2, A1, A0, (A1) .
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 A20, A19, A18, A17, A16, A15, A14, A13, and
A12 will uniquely select any sector.
BA
= Bank Address (A20 to A18)
RD
= Data read from location RA during read operation.
ID
= Device code/manufacture code for the address located by IA.
PD
= Data to be programmed at location PA. Data is latched on the rising edge of write pulse.
SPA = Sector group address to be protected. Set sector group address and (A6, A3, A2, A1, A0) = (0, 0, 0,
1, 0) .
SGA
= Sector Group Address. The combination of A20 to A12 will uniquely select any sector group.
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
MBM29DL32TF (Top Boot Type)
Word Mode : 1FFF80h to 1FFFFFh
Byte Mode : 3FFF00h to 3FFFFFh
MBM29DL32BF (Bottom Boot Type) Word Mode : 000000h to 00007Fh
Byte Mode : 00000h to 0000FFh
HRBA = Bank Address of the HiddenROM area
MBM29DL32TF (Top Boot Type)
: A20
= A19 = A18 = VIL
MBM29DL32BF (Bottom Boot Type) : A20
= A19 = A18 = VIH
The system should generate the following address patterns :
Word Mode : 555h or 2AAh to addresses A10 to A0
Byte Mode : AAAh or 555h to addresses A10 to A0, and A-1
Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
