PRODUCT PREVIEW
NOTES:
1. Bus operations are defined in Table 3.
2. X = Any valid address within the device.
BA = Address within the block.
IA = Identifier Code Address: see Figure 5 and Table 15.
QA = Query database Address.
PA = Address of memory location to be programmed.
RCD = Data to be written to the read configuration register. This data is presented to the device on A
16-1
; all
other address inputs
are ignored.
3. ID = Data read from Identifier Codes.
QD = Data read from Query database.
SRD = Data read from status register. See Table 18 for a description of the status register bits.
PD = Data to be programmed at location PA. Data is latched on the rising edge of WE#.
CC = Configuration Code.
4. The upper byte of the data bus (DQ
DQ
) during command writes is a “Don’t Care” in x16 operation.
5. Following the Read Identifier Codes command, read operations access manufacturer, device and block lock
codes. See
Read Identifier Codes Command
section for read identifier code data.
6. If the WSM is running, only DQ
7
is valid; DQ
15–
DQ
8
and DQ
6–
DQ
0
float, which places them in a high-impedance
state.
