General Description  
The A29L160B is a 16Mbit, 3.3 volt-only Flash memory  
organized as 2,097,152 bytes of 8 bits or 1,048,576 words of  
16 bits each. The 8 bits of data appear on I/O0 - I/O7; the 16  
bits of data appear on I/O0~I/O15. The A29L160B is offered in  
48-ball FBGA and 48-Pin TSOP packages. This device is  
designed to be programmed in-system with the standard  
system 3.3 volt VCC supply. Additional 12.0 volt VPP is not  
required for in-system write or erase operations. However,  
the A29L160B can also be programmed in standard EPROM  
programmers.  
The A29L160B has the first toggle bit, I/O6, which indicates  
whether an Embedded Program or Erase is in progress, or it  
is in the Erase Suspend. Besides the I/O6 toggle bit, the  
A29L160B has a second toggle bit, I/O2, to indicate whether  
the addressed sector is being selected for erase. The  
A29L160B also offers the ability to program in the Erase  
Suspend mode. The standard A29L160B offers access times  
of 70ns, allowing high-speed microprocessors to operate  
without wait states. To eliminate bus contention the device  
has separate chip enable (  
), write enable (  
) and  
WE  
CE  
output enable (  
) controls.  
OE  
The device requires only a single 3.3 volt power supply for  
both read and write functions. Internally generated and  
regulated voltages are provided for the program and erase  
operations.  
The A29L160B is entirely software command set compatible  
with the JEDEC single-power-supply Flash standard.  
Commands are written to the command register using  
standard microprocessor write timings. Register contents  
serve as input to an internal state-machine that controls the  
erase and programming circuitry. Write cycles also internally  
latch addresses and data needed for the programming and  
erase operations. Reading data out of the device is similar to  
reading from other Flash or EPROM devices.  
Device programming occurs by writing the proper program  
command sequence. This initiates the Embedded Program  
algorithm - an internal algorithm that automatically times the  
program pulse widths and verifies proper program margin.

Device erasure occurs by executing the proper erase  
command sequence. This initiates the Embedded Erase  
The hardware sector protection feature disables operations  
for both program and erase in any combination of the  
sectors of memory. This can be achieved via programming  
equipment.  
The Erase Suspend/Erase Resume feature enables the user  
to put erase on hold for any period of time to read data from,  
or program data to, any other sector that is not selected for  
erasure. True background erase can thus be achieved.

-
an internal algorithm that automatically  
preprograms the array (if it is not already programmed)  
before executing the erase operation. During erase, the  
device automatically times the erase pulse widths and  
verifies proper erase margin. The Unlock Bypass mode  
facilitates faster programming times by requiring only two  
write cycles to program data instead of four.

Data  
circuitry. A system reset would thus also reset the device,  
enabling the system microprocessor to read the boot-up  
firmware from the Flash memory.  
The device offers two power-saving features. When  
addresses have been stable for a specified amount of time,  
the device enters the automatic sleep mode. The system can  
also place the device into the standby mode. Power  
consumption is greatly reduced in both these modes.  
After a program or erase cycle has been completed, the  
device is ready to read array data or accept another  
command.  
The sector erase architecture allows memory sectors to be  
erased and reprogrammed without affecting the data  
contents of other sectors. The A29L160B is fully erased  
when shipped from the factory.

the device outputs array data in words and bytes. The  
internal state machine is set for reading array data upon

no spurious alteration of the memory content occurs during  
the power transition. No command is necessary in this mode  
to obtain array data. Standard microprocessor read cycles  
that assert valid addresses on the device address inputs  
produce valid data on the device data outputs. The device  
remains enabled for read access until the command register  
contents are altered.

program a word or byte, instead of four.  
The “Word/Byte Program Command Sequence” and “Unlock  
Bypass Command Sequence” has detail descriptions on  
programming data to the device using both standard and  
Unlock Bypass command sequence. An erase operation can  
erase one sector, multiple sectors, or the entire device. The

inputs required to uniquely select a sector. See the  
"Command Definitions" section for details on erasing a sector  
or the entire chip, or suspending/resuming the erase  
operation.  
After the system writes the autoselect command sequence,  
the device enters the autoselect mode. The system can then  
read autoselect codes from the internal register (which is  
separate from the memory array) on I/O7 - I/O0. Standard  
read cycle timings apply in this mode. Refer to the

protection, the sector address must appear on the  
appropriate highest order address bits. Refer to the  
corresponding Sector Address Tables. The Command  
Definitions table shows the remaining address bits that are  
don't care. When all necessary bits have been set as  
required, the programming equipment may then read the  
corresponding identifier code on I/O7 - I/O0.To access the  
autoselect codes in-system, the host system can issue the  
autoselect command via the command register, as shown in  
the Command Definitions table. This method does not  
require VID. See "Command Definitions" for details on using  
the autoselect mode.  
Autoselect Mode  
The autoselect mode provides manufacturer and device  
identification, and sector protection verification, through  
identifier codes output on I/O7 - I/O0. This mode is primarily  
intended for programming equipment to automatically match  
a
device to be programmed with its corresponding  
programming algorithm. However, the autoselect codes can  
also be accessed in-system through the command register.  
When using programming equipment, the autoselect mode  
requires VID (9.5V to 11.5V) on address pin A9. Address pins  
A6, A1, and A0 must be as shown in Autoselect Codes (High  
Voltage Method) table. In addition, when verifying sector

Sector Protection/Unprotection  
Temporary Sector Unprotect  
The hardware sector protection feature disables both  
program and erase operations in any sector. The hardware  
sector unprotection feature re-enables both program and  
erase operations in previously protected sectors.  
It is possible to determine whether a sector is protected or  
unprotected. See “Autoselect Mode” for details.  
This feature allows temporary unprotection of previous  
protected sectors to change data in-system. The Sector  
Unprotect mode is activated by setting the  
pin to VID.  
RESET  
During this mode, formerly protected sectors can be  
programmed or erased by selecting the sector addresses.  
Once VID is removed from the  
pin, all the previously  
RESET  
Sector protection / unprotection can be implemented via two  
methods. The primary method requires VID on the  
protected sectors are protected again. Figure 1 shows the  
algorithm, and the Temporary Sector Unprotect diagram  
shows the timing waveforms, for this feature.  
pin only, and can be implemented either in-system or  
RESET  
via programming equipment. Figure 2 shows the algorithm  
and the Sector Protect / Unprotect Timing Diagram illustrates  
the timing waveforms for this feature. This method uses  
standard microprocessor bus cycle timing. For sector  
unprotect, all unprotected sectors must first be protected  
prior to the first sector unprotect write cycle. The alternate  
method must be implemented using programming  
equipment. The procedure requires a high voltage (VID) on  
address pin A9 and the control pins.  
START  
The device is shipped with all sectors unprotected.  
It is possible to determine whether a sector is protected or  
unprotected. See "Autoselect Mode" for details.  
RESET = VID  
(Note 1)  
Hardware Data Protection  
The requirement of command unlocking sequence for  
programming or erasing provides data protection against  
inadvertent writes (refer to the Command Definitions table).  
In addition, the following hardware data protection measures  
prevent accidental erasure or programming, which might  
otherwise be caused by spurious system level signals during  
VCC power-up transitions, or from system noise. The device  
is powered up to read array data to avoid accidentally writing  
data to the array.

ready to read array data. The system can read CFI  
information at the addresses given in Table 5-8. In word  
mode, the upper address bits (A7-MSB) must be all zeros.  
To terminate reading CFI data, the system must write the  
reset command.  
The system can also write the CFI query command when the  
device is in the autoselect mode. The device enters the CFI  
query mode, and the system can read CFI data at the  
addresses given in Table 5-8. The system must write the  
reset command to return the device to the autoselect mode.  
Common Flash Memory Interface (CFI)  
The Common Flash Interface (CFI) specification outlines  
device and host system software interrogation handshake,  
which allows specific vendor-specified software algorithms to  
be used for entire families of devices. Software support can  
then be device-independent, JEDEC ID-independent, and  
forward- and backward-compatible for the specified flash  
device families. Flash vendors can standardize their existing  
interface for long-term compatibility.  
This device enters the CFI Query mode when the system  
writes the CFI Query command, 98h, to address 55h in word  
mode (or address AAh in byte mode), any time the device is

Command Definitions  
Autoselect Command Sequence  
Writing specific address and data commands or sequences  
into the command register initiates device operations. The  
Command Definitions table defines the valid register  
command sequences. Writing incorrect address and data  
values or writing them in the improper sequence resets the  
device to reading array data.  
The autoselect command sequence allows the host system to  
access the manufacturer and devices codes, and determine  
whether or not a sector is protected. The Command  
Definitions table shows the address and data requirements.  
This method is an alternative to that shown in the Autoselect  
Codes (High Voltage Method) table, which is intended for  
PROM programmers and requires VID on address bit A9.  
The autoselect command sequence is initiated by writing two  
unlock cycles, followed by the autoselect command. The  
device then enters the autoselect mode, and the system may  
read at any address any number of times, without initiating  
another command sequence.  
All addresses are latched on the falling edge of  
or

CE  
WE  
whichever happens later. All data is latched on the rising  
edge of or , whichever happens first. Refer to the  
WE  
CE  
appropriate timing diagrams in the "AC Characteristics"  
section.  
A read cycle at address XX00h retrieves the manufacturer  
code and another read cycle at XX11h retrieves the  
continuation code. A read cycle at address XX01h returns the  
device code. A read cycle containing a sector address (SA)  
and the address 02h in returns 01h if that sector is protected,  
or 00h if it is unprotected. Refer to the Sector Address tables  
for valid sector addresses.  
Reading Array Data  
The device is automatically set to reading array data after  
device power-up. No commands are required to retrieve  
data. The device is also ready to read array data after  
completing an Embedded Program or Embedded Erase  
algorithm. After the device accepts an Erase Suspend  
command, the device enters the Erase Suspend mode. The  
system can read array data using the standard read timings,  
except that if it reads at an address within erase-suspended  
sectors, the device outputs status data. After completing a  
programming operation in the Erase Suspend mode, the  
system may once again read array data with the same  
exception. See "Erase Suspend/Erase Resume Commands"  
for more information on this mode.  
The system must issue the reset command to re-enable the  
device for reading array data if I/O5 goes high, or while in the  
autoselect mode. See the "Reset Command" section, next.  
See also "Requirements for Reading Array Data" in the  
"Device Bus Operations" section for more information. The  
Read Operations table provides the read parameters, and  
Read Operation Timings diagram shows the timing diagram.  
The system must write the reset command to exit the  
autoselect mode and return to reading array data.  
Word/Byte Program Command Sequence  
The system may program the device by word or byte,  
depending on the state of the  
pin. Programming is a  
BYTE  
four-bus-cycle operation. The program command sequence is  
initiated by writing two unlock write cycles, followed by the  
program set-up command. The program address and data are  
written next, which in turn initiate the Embedded Program  
algorithm. The system is not required to provide further  
controls or timings. The device automatically provides  
internally generated program pulses and verify the  
programmed cell margin. Table 9 shows the address and data  
requirements for the byte program command sequence.  
When the Embedded Program algorithm is complete, the  
device then returns to reading array data and addresses are  
longer latched. The system can determine the status of the  
Reset Command  
Writing the reset command to the device resets the device to  
reading array data. Address bits are don't care for this  
command. The reset command may be written between the  
sequence cycles in an erase command sequence before  
erasing begins. This resets the device to reading array data.

Any commands written to the device during the Embedded  
Program Algorithm are ignored. Note that a hardware reset  
immediately terminates the programming operation. The Byte  
Program command sequence should be reinitiated once the  
device has reset to reading array data, to ensure data  
integrity.  
Programming is allowed in any sequence and across sector  
boundaries. A bit cannot be programmed from a “0” back to a  
“1”. Attempting to do so may halt the operation and set I/O5 to

Chip Erase Command Sequence  
Sequence  
Chip erase is a six-bus-cycle operation. The chip erase  
command sequence is initiated by writing two unlock cycles,  
followed by a set-up command. Two additional unlock write  
cycles are then followed by the chip erase command, which  
in turn invokes the Embedded Erase algorithm. The device  
does not require the system to preprogram prior to erase. The  
Embedded Erase algorithm automatically preprograms and  
verifies the entire memory for an all zero data pattern prior to  
electrical erase. The system is not required to provide any  
controls or timings during these operations. The Command  
Definitions table shows the address and data requirements  
for the chip erase command sequence.  
Any commands written to the chip during the Embedded  
Erase algorithm are ignored. The system can determine the  
status of the erase operation by using I/O7, I/O6, or I/O2. See  
"Write Operation Status" for information on these status bits.  
When the Embedded Erase algorithm is complete, the device

Sector Erase Command Sequence  
Sector erase is a six-bus-cycle operation. The sector erase  
command sequence is initiated by writing two unlock cycles,  
followed by a set-up command. Two additional unlock write  
cycles are then followed by the address of the sector to be  
erased, and the sector erase command. The Command  
Definitions table shows the address and data requirements  
for the sector erase command sequence.  
The device does not require the system to preprogram the  
memory prior to erase. The Embedded Erase algorithm  
automatically programs and verifies the sector for an all zero  
data pattern prior to electrical erase. The system is not  
required to provide any controls or timings during these  
operations.  
After the command sequence is written, a sector erase time-  
out of 50μs begins. During the time-out period, additional  
sector addresses and sector erase commands may be  
written. Loading the sector erase buffer may be done in any  
sequence, and the number of sectors may be from one sector  
to all sectors. The time between these additional cycles must  
be less than 50μs, otherwise the last address and command  
might not be accepted, and erasure may begin. It is  
recommended that processor interrupts be disabled during  
this time to ensure all commands are accepted. The  
interrupts can be re-enabled after the last Sector Erase  
command is written. If the time between additional sector  
erase commands can be assumed to be less than 50μs, the  
system need not monitor I/O3. Any command other than  
Sector Erase or Erase Suspend during the time-out period  
resets the device to reading array data. The system must  
rewrite the command sequence and any additional sector  
addresses and commands.  
Note : See the appropriate Command Definitions table for  
program command sequence.  
Figure 3. Program Operation  
Unlock Bypass Command Sequence  
The Unlock Bypass feature allows the system to program  
bytes or words to the device faster than using the standard  
program command sequence. The Unlock Bypass command  
sequence is initiated by first writing two unlock cycles. This is  
followed by a third write cycle containing the Unlock Bypass  
command, 20h. The device then enters the Unlock Bypass  
mode. A two-cycle Unlock Bypass program command  
sequence is all that is required to program in this mode. The  
first cycle in this sequence contains the Unlock Bypass  
program command, A0h; the second cycle contains the  
program address and data. Additional data is programmed in  
the same manner. This mode dispenses with the initial two  
unlock cycles required in the standard program command  
sequence, resulting in faster total programming time. Table 9  
shows the requirements for the command sequence.  
During the Unlock Bypass mode, only the Unlock Bypass  
Program and Unlock Bypass Reset commands are valid. To  
exit the Unlock Bypass mode, the system must issue the two-  
cycle Unlock Bypass reset command sequence. The first  
cycle must contain the data 90h; the second cycle the data

Erase Suspend/Erase Resume Commands  
The Erase Suspend command allows the system to interrupt  
a sector erase operation and then read data from, or  
program data to, any sector not selected for erasure. This  
command is valid only during the sector erase operation,  
including the 50μs time-out period during the sector erase  
command sequence. The Erase Suspend command is  
ignored if written during the chip erase operation or  
Embedded Program algorithm. Writing the Erase Suspend  
command during the Sector Erase time-out immediately  
terminates the time-out period and suspends the erase  
operation. Addresses are "don't cares" when writing the

When the Erase Suspend command is written during a

Erasure Completed  
After the erase operation has been suspended, the system  
can read array data from or program data to any sector not  
selected for erasure. (The device "erase suspends" all  
sectors selected for erasure.) Normal read and write timings  
and command definitions apply. Reading at any address  
within erase-suspended sectors produces status data on I/O7  
- I/O0. The system can use I/O7, or I/O6 and I/O2 together, to  
determine if a sector is actively erasing or is erase-  
suspended. See "Write Operation Status" for information on  
these status bits.  
Note :  
1. See the appropriate Command Definitions table for erase  
command sequences.  
2. See "I/O  
3
: Sector Erase Timer" for more information.  
Figure 4. Erase Operation  
After an erase-suspended program operation is complete,  
the system can once again read array data within non-  
suspended sectors. The system can determine the status of  
the program operation using the I/O7 or I/O6 status bits, just  
as in the standard program operation. See "Write Operation  
Status" for more information.  
The system may also write the autoselect command  
sequence when the device is in the Erase Suspend mode.  
The device allows reading autoselect codes even at  
addresses within erasing sectors, since the codes are not  
stored in the memory array. When the device exits the  
autoselect mode, the device reverts to the Erase Suspend  
mode, and is ready for another valid operation. See  
"Autoselect Command Sequence" for more information.

cannot distinguish whether the sector is actively erasing or is

device is actively erasing, or is in Erase Suspend, but cannot  
distinguish which sectors are selected for erasure. Thus, both  
status bits are required for sector and mode information.  
Refer to Table 10 to compare outputs for I/O2 and I/O6.  
Figure 6 shows the toggle bit algorithm in flowchart form, and  
the section " I/O2: Toggle Bit II" explains the algorithm. See  
also the " I/O6: Toggle Bit I" subsection. Refer to the Toggle  
Bit Timings figure for the toggle bit timing diagram. The I/O2

I/O6: Toggle Bit I  
Toggle Bit I on I/O6 indicates whether an Embedded Program  
or Erase algorithm is in progress or complete, or whether the  
device has entered the Erase Suspend mode. Toggle Bit I  
may be read at any address, and is valid after the rising edge

WE  
Refer to Figure 6 for the following discussion. Whenever the  
system initially begins reading toggle bit status, it must read  
I/O7 - I/O0 at least twice in a row to determine whether a  
toggle bit is toggling. Typically, a system would note and store  
the value of the toggle bit after the first read. After the second  
read, the system would compare the new value of the toggle  
bit with the first. If the toggle bit is not toggling, the device has  
completed the program or erase operation. The system can  
read array data on I/O7 - I/O0 on the following read cycle.  
However, if after the initial two read cycles, the system  
determines that the toggle bit is still toggling, the system also  
should note whether the value of I/O5 is high (see the section  
on I/O5). If it is, the system should then determine again  
whether the toggle bit is toggling, since the toggle bit may  
have stopped toggling just as I/O5 went high. If the toggle bit  
is no longer toggling, the device has successfully completed  
the program or erase operation. If it is still toggling, the device  
did not complete the operation successfully, and the system  
must write the reset command to return to reading array data.  
The remaining scenario is that the system initially determines  
that the toggle bit is toggling and I/O5 has not gone high. The  
system may continue to monitor the toggle bit and I/O5  
through successive read cycles, determining the status as  
described in the previous paragraph. Alternatively, it may  
choose to perform other system tasks. In this case, the  
system must start at the beginning of the algorithm when it  
returns to determine the status of the operation (top of Figure  
6).

time-out.  
During an Embedded Program or Erase algorithm operation,  
successive read cycles to any address cause I/O6 to toggle.  
(The system may use either  
or

cycles.) When the operation is complete, I/O6 stops toggling.  
After an erase command sequence is written, if all sectors  
selected for erasing are protected, I/O6 toggles for  
approximately 100μs, then returns to reading array data. If not  
all selected sectors are protected, the Embedded Erase  
algorithm erases the unprotected sectors, and ignores the  
selected sectors that are protected.  
The system can use I/O6 and I/O2 together to determine  
whether a sector is actively erasing or is erase-suspended.  
When the device is actively erasing (that is, the Embedded  
Erase algorithm is in progress), I/O6 toggles. When the device  
enters the Erase Suspend mode, I/O6 stops toggling.  
However, the system must also use I/O2 to determine which  
sectors are erasing or erase-suspended. Alternatively, the  
system can use I/O7 (see the subsection on " I/O7 :  
Data  
Polling").  
If a program address falls within a protected sector, I/O6  
toggles for approximately 2μs after the program command  
sequence is written, then returns to reading array data.  
I/O6 also toggles during the erase-suspend-program mode,  
and stops toggling once the Embedded Program algorithm is  
complete.  
The Write Operation Status table shows the outputs for  
Toggle Bit I on I/O6. Refer to Figure 6 for the toggle bit  
algorithm, and to the Toggle Bit Timings figure in the "AC  
Characteristics" section for the timing diagram. The I/O2 vs.  
I/O6 figure shows the differences between I/O2 and I/O6 in  
graphical form. See also the subsection on " I/O2: Toggle Bit  
II".  
I/O5: Exceeded Timing Limits  
I/O5 indicates whether the program or erase time has  
exceeded a specified internal pulse count limit. Under these  
conditions I/O5 produces a "1." This is a failure condition that  
indicates the program or erase cycle was not successfully  
completed.  
(August, 2014, Version 1.2)  
19  
AMIC Technology, Corp.  
A29L160B Series  
The I/O5 failure condition may appear if the system tries to  
program a "1 "to a location that is previously programmed to  
"0." Only an erase operation can change a "0" back to a "1."  
Under this condition, the device halts the operation, and  
when the operation has exceeded the timing limits, I/O5  
produces a "1."

Under both these conditions, the system must issue the reset  
command to return the device to reading array data.  
I/O3: Sector Erase Timer  
After writing a sector erase command sequence, the system  
may read I/O3 to determine whether or not an erase  
operation has begun. (The sector erase timer does not apply  
to the chip erase command.) If additional sectors are  
selected for erasure, the entire time-out also applies after  
each additional sector erase command. When the time-out is  
complete, I/O3 switches from "0" to "1." The system may  
ignore I/O3 if the system can guarantee that the time  
between additional sector erase commands will always be  
less than 50μs. See also the "Sector Erase Command  
Sequence" section.

erase operation is complete. If I/O3 is "0", the device will  
accept additional sector erase commands. To ensure the  
command has been accepted, the system software should  
check the status of I/O3 prior to and following each  
subsequent sector erase command. If I/O3 is high on the

Notes:  
1. Typical program and erase times assume the following conditions: 25°C, 3.0V VCC, 10,000 cycles. Additionally, programming  
typically assumes checkerboard pattern.  
2. Under worst case conditions of 90°C, VCC = 2.7V, 100,000 cycles.  
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes  
program faster than the maximum byte program time listed. If the maximum byte program time given is exceeded, only then  
does the device set I/O5 = 1. See the section on I/O5 for further information.  
4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.  
5. System-level overhead is the time required to execute the four-bus-cycle command sequence for programming. See Table 9  
for further information on command definitions.  
6. The device has a guaranteed minimum erase and program cycle endurance of 100,000 cycles.
