Command Definitions
Table 10.
Am29PL160C 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.
3.
See Table 1 for description of bus operations.
All values are in hexadecimal.
Except for the read cycle and the fourth cycle of the autoselect
command sequence, all bus cycles are write cycles.
Data bits DQ15–DQ8 are don’t cares for unlock and command
cycles.
Address bits A19–A11 are don’t cares for unlock and command
cycles, unless SA or PA required.
No unlock or command cycles required when reading array data.
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).
The fourth cycle of the autoselect command sequence is a read
cycle.
4.
5.
6.
7.
8.
9.
The data is 00h for an unprotected sector and 01h for a protected
sector. See “Autoselect Command Sequence” for more
information.
10. Command is valid when device is ready to read array data or
when device is in autoselect mode.
11. The Unlock Bypass command is required prior to the Unlock
Bypass Program command.
12. The Unlock Bypass Reset command is required to return to
reading array data when the device is in the unlock bypass
mode.
13. 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.
14. The Erase Resume command is valid only during the Erase Sus-
pend mode.
