HY29LV160
The system must write the Reset command to exit
the Electronic ID mode and return to reading ar-
ray data.
Query Command and Common Flash Inter-
face (CFI) Mode
The HY29LV160 is capable of operating in the
Common Flash Interface (CFI) mode. This mode
allows the host system to determine the manufac-
turer of the device, its operating parameters, its
configuration and any special command codes that
the device may accept. With this knowledge, the
system can optimize its use of the chip by using
appropriate timeout values, optimal voltages and
commands necessary to use the chip to its full
advantage.
Two commands are employed in association with
CFI mode. The first places the device in CFI mode
(Query command) and the second takes it out of
CFI mode (Reset command). These are described
in Table 6.
The single cycle Query command is valid only
when the device is in the Read mode, including
during Erase Suspend and Standby states and
while in Electronic ID mode, but is ignored other-
wise. Read cycles at appropriate addresses while
in the Query mode provide CFI data as described
later in this section. Write cycles are ignored, ex-
cept for the Reset command.
The Reset command returns the device from the
CFI mode to the array Read mode, or to the Erase
Suspend mode if the device was in that mode prior
to entering CFI mode, or to the Electronic ID mode
if the device was in that mode prior to entering
CFI mode. The command is valid only when the
device is in the CFI mode and as otherwise de-
scribed for the normal Reset command.
Tables 7 - 10 specify the data provided by the
HY29LV160 during CFI mode. Data at unspeci-
fied addresses reads out as 0x00. Note that a
value of 0x00 for a data item normally indicates
that the function is not supported. All values in
these tables are in hexadecimal.
