MBM29DL16XTE/BE70/90
Notes: • Address bits A19 to A11 = X = “H” or “L” for all address commands except or Program Address (PA), Sector
Address (SA), and Bank Address (BA).
•
•
Bus operations are defined in “MBM29DL16XTE/BE User Bus Operations Tables (BYTE = VIH and
BYTE = VIL)”.
RA:
IA :
Address of the memory location to be read
Autoselect read address that sets both the bank address specified at (A19, A18, A17, A16, A15) and
all the other A6, A1, A0, (A-1).
PA:
SA:
Address of the memory location to be programmed
Addresses are latched on the falling edge of the write pulse.
Address of the sector to be erased. The combination of A19, A18, A17, A16, A15, A14, A13, and A12 will
uniquely select any sector.
BA:
RD:
ID :
PD:
Bank Address (A19 to A15)
Data read from location RA during read operation.
Device code/manufacture code for the address located by IA.
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 (SGA) and (A6, A1, A0) = (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
29DL16XTE (Top Boot Type)
Word Mode: 0F8000h to 0FFFFFh
Byte Mode: 1F0000h to 1FFFFFh
29DL16XBE (Bottom Boot Type) Word Mode: 000000h to 007FFFh
Byte Mode: 000000h to 00FFFFh
•
•
HRBA: Bank Address of the HiddenROM area
29DL16XTE (Top Boot Type)
:A19 = A18= A17 = A16 = A15 = VIH
29DL16XBE (Bottom Boot Type) :A19 = A18= A17 = A16 = A15 = VIL
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.
Command combinations not described in Command Definitions table are illegal.
*1: Both of these reset commands are equivalent.
*2: This command is valid during Fast Mode.
*3: This command is valid while RESET = VID (except during HiddenROM MODE).
*4: The valid addresses are A6 to A0.
*5: This command is valid during HiddenROM mode.
*6: The data “00h” is also acceptable.
*7: The fourth bus cycle is only for read.
