Legend: L = VIL, H = VIH, X = VIL or VIH. See DC Characteristics for voltage levels.
*1 : Other operations except for indicated this column are inhibited.
*2 : WE can be VIL if OE is VIL, OE at VIH initiates the write operations.
*3 : Do not apply CEf = VIL, CE1s = VIL and CE2s = VIH at a time.
*4 : It is also used for the extended sector group protections.
*5 : WP/ACC = VIL; protection of boot sectors.
WP/ACC = VIH; removal of boot sectors protection.
WP/ACC = VACC (9V) ; Program time will reduce by 40%.

■ABSOLUTE MAXIMUM RATINGS
*1 : Minimum DC v oltage on input or I/O pins is –0.3 V. During voltage transitions, input or I/O pins may undershoot
VSS to –1.0 V for periods of up to 20 ns. Maximum DC voltage on input or I/O pins is VCCf+0.3 V or
VCCs+0.4 V. During voltage transitions, input or I/O pins may overshoot to VCCf+1.0 V or VCCs + 1.0 V for periods
of up to 20 ns.
*2 : Minimum DC input voltage on RESET pin is –0.5 V. During voltage transitions, RESET pins may undershoot
VSS to –2.0 V f or periods of up to 20 ns. Voltage diff erence between input and supply v oltage (VIN-VCCf or VCCs)
does not exceed +9.0 V. Maximum DC input voltage on RESET pins is +13.0 V which may overshoot to
+14.0 V for periods of up to 20 ns.
*3 : Minimum DC input v oltage on WP/A CC pin is –0.5 V. During voltage tr ansitions, WP/A CC pin may undershoot
Vss to –2.0 V for periods of up to 20 ns. Maximum DC input voltage on WP/ACC pin is +10.5 V which may
overshoot to +12.0 V for periods of up to 20 ns, when VCCf is applied.
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.
■RECOMMENDED OPERATING CONDITIONS
Note: Operating ranges define those limits between which the functionality of the device is guaranteed.
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor de vices within the recommended operating conditions . Oper ation outside
these ranges may adversely affect reliability and could result in device failure.
No warr anty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representative beforehand.

*1 : Both of these reset commands are equivalent.
*2 : This command is valid during Fast Mode.
*3 : This command is valid while RESET = VID.
*4 : The valid address are A6 to A0.
*5 : This command is valid during HiddenROM mode.
*6 : The date “00h” is also acceptable.
Notes: •Address bits A20 to A11 = X = “H” or “L” for all address commands e xcept or Progr am Address (PA) , Sector
Address (SA) , Bank Address (BA) .
•Bus operations are defined in
“User Bus Operations Tables” (■DEVICE BUS OPERATION).
•RA = Address of the memory location to be read
PA = Address of the memory location to be programmed
Addresses are latched on the falling edge of the write pulse.
SA = Address of the sector to be erased. The combination of A20, A19, A18, A17, A16, A15, A14, A13, and
A12 will uniquely select any sector.
BA = Bank Address (A20 to A18)
•RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the rising edge of write pulse.
•SPA = Sector group address to be protected. Set sector group address and (A6, A3, A2, A1, A0) = (0, 0, 0,
1, 0) .
SD = Sector group protection verify data. Output 01h at protected sector group addresses and output
00h at unprotected sector group addresses.
•HRA = Address of the HiddenROM area
Top Boot Type : 1FF000h to 1FF07Fh
Bottom Boot Type : 000000h to 00007Fh
•HRBA = Bank Address of the HiddenROM area
Top Boot Type : A20 = A19 = A18 = 1
Bottom Boot Type : A20 = A19 = A18 = 0
•The system should generate the following address patterns :
Word Mode : 555h or 2AAh to addresses A10 to A0
•Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
•The command combinations not described in “Command Definitions Table” are illegal.

■HANDLING OF PACKAGE
Please handle this package carefully since the sides of package create acute angles.
■CAUTION
• The high voltage (VID) cannot apply to address pins and control pins except RESET.
Exception is when autoselect and sector group protect function are used, then the high voltage (VID) can be
applied to RESET.
• Without the high voltage (VID) , sector group protection can be achieved by using “Extended Sector Group
