5. Command writes involving block erase or word write are reliably
executed when F-VPP = VPPH and F-VCC = 2.7 V to 3.6 V. Block
erase or word write with VIH < RP < VHH produce spurious results
and should not be attempted.
6. Never hold F-OE LOW and F-WE LOW at the same time.

NOTES:
1. Check RY/BY or SR.7 to determine block erase or word write
completion. SR.6 - SR.0 are invalid while SR.7 = 0.
2. If both SR.5 and SR.4 are ‘1’s after a block erase attempt, an
improper command sequence was entered.
3. SR.3 does not provide a continuous indication of F-VPP level. The
WSM interrogates and indicates the F-VPP level only after Block
Erase or Word Write command sequences. SR.3 is not guaranteed
to report accurate feedback only when F-VPP ≠ VPPH1, VPPH2.
4. The WSM interrogates the F-WP and F-RP only after Block Erase
or Word Write command sequences. It informs the system,
depending on the attempted operation, if the F-WP is not VIH or
F-RP is not VHH.
5. SR.0 is reserved for future use and should be masked out when
polling the status register.
SR.3 = VPP Status (VPPS)

0 = F-VPP Okay
SR.2 = Word Write Suspend Status (WWSS)

0 = Word Write in Progress/Completed
SR.1 = Device Protect Status (DPS)

GENERAL DESIGN GUIDELINES
Supply Power
Maximum difference (between F-VCC and S-VCC) of
the voltage is less than 0.3 V.
Stacked Chip (16M Flash & 2M SRAM)
Data Protection Through F-VPP
When the level of F-VPP is lower than F-VPPLK (lockout voltage), write operation on the flash memory is disabled. All blocks are locked and the data in the blocks
are completely write protected.
Power Supply and Chip Enable of Flash
Memory and SRAM
For the lockout voltage refer to the ‘DC Characteristics’ section.
S-CE1 should not be LOW and S-CE2 should not be
HIGH when F-CE is LOW simultaneously.
Data Protection During Voltage Transition
If the two memories are active together, they may
not operate normally because of interference noises or
data collision on DQ bus.
DATA PROTECTION THROUGH F-RP
When the F-RP is kept LOW during power up and
power down sequence, write operation on the flash
memory is disabled, write protecting all blocks.
Both F-VCC and S-VCC need to be applied by the
recommended supply voltage at the same time except
SRAM data retention mode.
Power Up Sequence
When turning on Flash memory power supply, keep
F-RP LOW. After F-VCC reaches over 2.7 V, keep F-RP
LOW for more than 100 ns.
Device Decoupling
The power supply needs to be designed carefully
because one of the SRAM and the Flash Memory is in
standby mode when the other is active. A careful
decoupling of power supplies is necessary between
SRAM and Flash Memory. Note peak current caused
by transition of control signals (F-CE, S-CE1, S-CE2).
FLASH MEMORY DATA PROTECTION
Noises having a level exceeding the limit specified in
the specification may be generated under specific
operating conditions on some systems.
Such noises, when induced onto F-WE signal or
power supply may be interpreted as false commands,
causing undesired memory updating.
To protect the data stored in the flash memory
against unwanted overwriting, systems operating with
the flash memory should have the following write protect designs, as appropriate:
Protecting Data in Specific Block
By setting a F-WP to LOW, only the boot block can
be protected against overwriting. Parameter and main
blocks cannot be locked. System program, etc., can be
locked by storing them in the boot block. When a high
voltage is applied to F-RP, overwrite operation is
enabled for all blocks.
For further information on setting/resetting of block
bit, and controlling of F-WP and F-RP, refer to the
‘Command Definitions’ section.
22
For details of F-RP control refer to the ‘Flash
Memory AC Electrical Characteristics’ section.
DESIGN CONSIDERATIONS
Power Supply Decoupling
To avoid a bad effect on the system by flash memory
power switching characteristics, each device should
have a 0.1 µF ceramic capacitor connected between its
VCC and GND and between its VPP and GND. LOW
inductance capacitors should be placed as close as
possible to package leads.
VPP Trace on Printed Circuit Boards
Updating the memory contents of flash memories
that reside in the target system requires that the printed
circuit board designer pay attention to the VPP Power
Supply trace. Use similar trace widths and layout considerations given to the VCC power bus.
The Inhibition of Overwrite Operation
Please do not execute reprogramming ‘0’ for the bit
which has already been programmed ‘0’. Overwrite
operation may generate unerasable bit. In case of
reprogramming ‘0’ to the data which has been programmed ‘1’.
• Program ‘0’ for the bit in which you want to change
data from ‘1’ to ‘0’.
• Program ‘1’ for the bit which has already been programmed ‘0’.
For
example,
changing
data
from
‘1011110110111101’ to ‘1010110110111100’ requires
‘1110111111111110’ programming.
Power Supply
Block erase, full chip erase, word write and lock-bit
configuration with an invalid VPP (see ‘DC Characteristics’) produce spurious results and should not be
attempted. Device operations at invalid VCC voltage
product spurious results and should be attempted.

In case Sharp is unable to repair or replace such Products, refunds will be issued to the distributor in the amount of distributor cost.
