Legend
X = Don’t care
RA = Read Address of memory location to be read.
RD = Read Data read from location RA during read operation.
PA = Program Address. Addresses latch on falling edge of WE# or CE# pulse,
whichever happens later.
PD = Program Data for location PA. Data latches on rising edge of WE# or CE#
pulse, whichever happens first.
SA = Sector Address of sector to be verified (in autoselect mode) or erased.
Address bits A21–A15 uniquely select any sector.
WBL = Write Buffer Location. Address must be within same write buffer page as
PA.
BC = Byte Count. Number of write buffer locations to load minus 1.
Notes
1. See Table 7.1 on page 22 for description of bus operations.
2. All values are in hexadecimal.
3. Shaded cells indicate read cycles. All others are write cycles.
4. During unlock and command cycles, when lower address bits are 555 or
AAA as shown in table, address bits above A11 are don’t care.
5. Unless otherwise noted, address bits A21–A11 are don’t cares.
6. No unlock or command cycles required when device is in read mode.
7. Reset command is required to return to read mode (or to erase-suspend-
read mode if previously in Erase Suspend) when device is in autoselect
mode, or if DQ5 goes high while device is providing status information.
8. Fourth cycle of autoselect command sequence is a read cycle. Data bits
DQ15–DQ8 are don’t care. See Autoselect Command Sequence on page 53
or more information.
9. For S29GL064A and S29GL032A Device ID must be read in three cycles.
1. For S29GL016A, Device ID must be read in one cycle.
2. Refer to Table 7.12 on page 40, for data indicating Secured Silicon Sector
factory protect status.
3. Data is 00h for an unprotected sector group and 01h for a protected sector
group.
4. Total number of cycles in command sequence is determined by number of
bytes written to write buffer. Maximum number of cycles in command
sequence is 37, including Program Buffer to Flash command.
5. Command sequence resets device for next command after aborted write-to-
buffer operation.
6. System may read and program in non-erasing sectors, or enter autoselect
mode, when in Erase Suspend mode. Erase Suspend command is valid only
during a sector erase operation.
7. Erase Resume command is valid only during Erase Suspend mode.
8. Command is valid when device is ready to read array data or when device is
in autoselect mode.
9. Refer to Table 7.12 on page 40, for individual Device IDs per device density
and model number.
