Command Definitions
Table 12.
Am29SL160C 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 A19–A12 uniquely select any sector.
Notes:
1.
2.
See
Table 1, on page 11
for description of bus operations.
All values are in hexadecimal.
3.
Except for the read cycle and the fourth cycle of the autoselect
command sequence, all bus cycles are write cycles.
4.
Data bits DQ15–DQ8 are don’t cares in byte mode.
5.
Unless otherwise noted, address bits A19–A11 are don’t cares.
6.
No unlock or command cycles required when in read mode.
7.
The Reset command is required to return to the read mode (or to
the erase-suspend-read mode if previously in Erase Suspend)
when in the autoselect mode, or if DQ5 goes high (while providing
status information).
8.
The fourth cycle of the autoselect command sequence is a read
cycle.
9.
The data is 00h for an unprotected sector and 01h for a protected
sector. Data bits DQ15–DQ8 are don’t care. See the Autoselect
Command Sequence section for more information.
10. The Unlock Bypass command is required prior to the Unlock
Bypass Program command.
11. The Unlock Bypass Reset command is required to return to the
read mode when in the unlock bypass mode.
12. The system may read and program in 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.
13. The Erase Resume command is valid only during the Erase
Suspend mode.
14. Command is valid when device is ready to read array data or
when device is in autoselect mode.
