SIRUSFLASH MEMORY
PRELIMINARY
interface (CFI) that permits software algorithms to be
used for entire families of devices. The software is de-
vice-independent, JEDEC ID-independent with for-
ward and backward compatibility.
Additionally, the scalable command set (SCS) al-
lows 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 trans-
fer rates and minimizes the device and system-level
implementation costs.
To optimize the processor-memory interface, the
device accommodates V
PEN
, which is switchable during
block erase, program, or lock bit configuration, or
hardwired to V
CC
, depending on the application. V
PEN
is
treated as an input pin to enable erasing, program-
ming, and block locking. When V
PEN
is lower than the
V
CC
lockout voltage (V
LKO
), 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 unsuspended blocks.
V
PEN
serves as an input with 2.7V, 3.3V, or 5V for
application programming. V
PEN
in this SirusFlash
fam-
ily can provide data protection when connected to
ground. This pin also enables program or erase lockout
during power transition.
Micron’s SirusFlash devices offer individual block
locking that can lock and unlock a block using the sec-
tor 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 status
and status masking. This status indicator minimizes
central processing unit (CPU) 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 con-
figuration. When HIGH, STS indicates that the ISM is
ready for a new command.
Three chip enable (CE) pins are used for enabling
and disabling the device by activating the device’s
control logic, input buffer, decoders, and sense ampli-
fiers.
BYTE# enables selecting x8 or x16 READs/WRITEs
to the device. BYTE# at logic LOW selects an 8-bit mode
with address A0 selecting between the low byte and
the high byte. BYTE# at logic HIGH enables 16-bit op-
eration.
RP# is used to reset the device. When the device is
disabled and RP# is at V
CC
, the standby mode is en-
abled. A reset time (
t
RWH) is required after RP#
switches HIGH until outputs are valid. Likewise, the
device has a wake time (
t
RS) from RP# HIGH until
WRITEs to the command user interface (CUI) are rec-
ognized. When RP# is at GND, it provides write protec-
tion, resets the ISM, and clears the status register.
