Command Definitions
Table 4.
Am29LV040B Command Definitions
Legend:
X = Don’t care
RA = Address of the memory location to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed.
Addresses latch on the falling edge of the WE# or CE# pulse,
whichever happens later.
PD = Data to be programmed at location PA. Data latches on the
rising edge of WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or
erased. Address bits A18–A13 uniquely select any sector.
Notes:
1. See Table 1 for description of bus operations.
2. All values are in hexadecimal.
3. Except when reading array or autoselect data, all command
bus cycles are write operations.
4. Address bits A18–A11 are don’t cares for unlock and
command cycles.
5. No unlock or command cycles required when reading array
data.
6. The Reset command is required to return to reading array
data when device is in the autoselect mode, or if DQ5 goes
high (while the device is providing status data).
7. The fourth cycle of the autoselect command sequence is a
read cycle.
8. The data is 00h for an unprotected sector and 01h for a
protected sector. See “Autoselect Command Sequence” for
more information.
9. The Unlock Bypass command is required prior to the Unlock
Bypass Program command.
10. The Unlock Bypass Reset command is required to return to
reading array data when the device is in the unlock bypass
mode.
11. The system may read and program n non-erasing sectors, or
enter the autoselect mode, when in the Erase Suspend
mode. The Erase Suspend command is valid only during a
sector erase operation.
12. The Erase Resume command is valid only during the Erase
Suspend mode.
