NOTES:
1. Bus operations are defined in Table 4.
2. First bus cycle command address should be the same as the second cycle address.
X=Any valid address within the device.
PA=Address within the selected partition.
IA=Identifier codes address (See Table 6 through Table 8).
QA=Query codes address. Refer to Appendix of LH28F320BX/LH28F640BX series for details.
BA=Address within the block being erased, set/cleared block lock bit or set block lock-down bit.
WA=Address of memory location for the Program command or the first address for the Page Buffer Program command.
OA=Address of OTP block to be read or programmed (See Figure 4).
RCRC=Read configuration register code presented on the addresses A0-A15.
PCRC=Partition configuration register code presented on the address A0-A15.
3. ID=Data read from identifier codes. (See Table 6 through Table 8).
QD=Data read from query database. Refer to Appendix of LH28F320BX/LH28F640BX series for details.
SRD=Data read from status register. See Table 9 for a description of the status register bits.
WD=Data to be programmed at location WA. Data is latched on the rising edge of WE# or CE# (whichever goes high
first).
OD=Data to be programmed at location OA. Data is latched on the rising edge of WE# or CE# (whichever goes high
first).
N-1=N is the number of the words to be loaded into a page buffer.
4. Following the Read Identifier Codes/OTP command, read operations access manufacturer code, device code, block lock
configuration code, read configuration register code, partition configuration register code and the data within OTP block
(See Table 6 through Table 8).
The Read Query command is available for reading CFI (Common Flash Interface) information.
5. Block erase, full chip erase or (page buffer) program cannot be executed when the selected block is locked. Unlocked
block can be erased or programmed when RST# is VIH.
6. Either 40H or 10H are recognized by the CUI (Command User Interface) as the program setup.
Synchronous burst mode will be available for future device.
