General Description
ASI’s, AS28F128J3M Enhanced or Mil-Temp variant of Micron’s
Q-Flash family of devices, is a nonvolatile, electrically block-
erasable (FLASH), programmable memory device manufactured
using Micron’s 0.15um process technology.
This device
containing 134,217,728 bits organized as either 16,777,218 (x8)
or 8,388,608 bytes (x16). The device is uniformly sectored with
one hundred and twenty eight 128KB ERASE blocks.
This device features in-system block locking. They also have a
Common FLASH Interface [CFI] that permits software algorithms
to be used for entire families of devices. The software is device-
independent, JEDEC ID-independent with forward and backward
compatibility.

Additionally, the Scaleable Command Set [SCS] allows a single,
simple software driver in all host systems to work with all SCS
compliant FLASH memory devices. The SCS provides the fastest
system/device data transfer rates and minimizes the device and
system-level implementation costs.
To optimize the processor-memory interface, the device
accommodates VPEN, which is switchable during BLOCK
ERASE, PROGRAM, or LOCK BIT configurations and in
addition can be hard-wired to VCC all dependent on the end
application(s). VPEN is treated as an input pin to enable
ERASING, PROGRAMMING, and BLOCK LOCKING. When
VPEN is lower than the VCC lockout voltage (VLKO), all
program functions are disabled. BLOCK ERASE SUSPEND
mode enables the user to stop BLOCK ERASE to READ data
from or PROGRAM data to any other blocks. Similarly,
PROGRAM SUSPEND mode enables the user to SUSPEND
PROGRAMMING to READ data or execute code from any un-
suspended block(s).
AS28F128J3MRG
Revision 5.0 11/23/04
VPEN serves as an input with 2.7V, 3.3V or 5V levels for
application programming. VPEN in this Q-Flash device can
provide data protection when connected to ground. This pin also
enables PROGRAM or ERASE LOCKOUT functions/controls
during power transitions.
This device is an even-sectored device architecture offering
individual BLOCK LOCKING that can LOCK and UN-LOCK a
block using the SECTOR LOCK BITS command sequence.
Status [STS] is a logic signal output that gives an additional
indicator of the internal state machine [ISM] activity by providing
a hardware signal of both the status and status masking. This
status indicator minimizes central processing unit overhead and
system power consumption. In the default mode, STS acts as an
RY/BY\ pin. When LOW, STS indicates that the ISM is
performing a BLOCK ERASE, PROGRAM, or LOCK BIT
configuration. When HIGH, STS indicates that the ISM is ready
for a new command.

Three Chip Enable (CEx) pins are used for enabling and disabling
the device by activating the device’s control logic, input buffer,
decoders, and sense amplifiers.
BYTE\ enables the device to be used in x8 or x16 configuration.
Byte=Low (logic 0) selects and 8-bit mode with address zero (A0)
selecting the High or Low Byte and Byte=High (logic 1) selects
the 16-bit or Word mode. When the device is in Word mode,
address one (A1) becomes the low order address bit and address
zero (A0) becomes a no-connect (NC).
RP\ is used to reset the device. When the device is disabled and
RP\ is at VCC, the STANDBY mode is enabled. A reset time
(tRWH) is required after RP\ switches to a High (logic 1) and the
outputs become valid. Likewise, the device has a wake time (tRS)
from RP\ High until WRITES to the Command User Interface
[CUI] are recognized, RESETS the ISM and clears the status
register.

1: All specified voltages are with respect to GND. Minimum DC
voltage is -0.5v on input/output pins and -0.2v on Vcc and VPEN
pins. During transitions, this level may undershoot to -2.0v for
periods </= 20ns. Maximum DC voltage on input/output pins,
Vcc and VPEN is VCC+0.5V which, during transitions, may
overshoot to Vcc + 2.0v for periods <20ns.

In default mode, STA is VOL when the ISM is executing internal Block Erase, Program, or lock bit configuration algorithms. It is VOH when the ISM
is not busy, in block erase suspend mode, program suspend mode, or reset/power-down mode.

Following the READ IDENTIFIER CODES command, READ operations access manufacturer, device, and block lock codes.
If the ISM is running, only DQ7 is valid; DQ15-DQ8 and DQ6-DQ0 are placed in High-Z
After the WRITE-to-BUFFER command is issued, check the XSR to make sure a buffer is available for WRITING
The number of Bytes/words to be written to the write buffer = n+1, where n=byte/word count argument. Count ranges on this device
for byte mode are n=00H to n=1Fh and for word mode, n=0000h to 000Fh. The third and consecutive bus cycles, as determined by n,
are for writing data into the write buffer. The CONFIRM command (D0h) is expected after exactly n+1 WRITE cycles; any other
command at that point in the sequence aborts the WRITE-to-BUFFER operation.
The WRITE-to-BUFFER or ERASE operation does not begin until a CONFIRM command (D0h) is issued
Attempts to issue a BLOCK ERASE or PROGRAM to a locked block will fail
Etiher 40h or 10h is recognized by the ISM as the byte/word program setup
PROGRAM SUSPEND can be issued after either the WRITE-to-BUFFER or WORD/BYTE PROGRAM operation is inititated.
The CLEAR BLOCK LOCK BITS operation simultaneously clears all block lock bits.
