■ CHIP CONFIGURATION
The miniature cards use 2 or 4 pcs of Flash Memory. 2 pcs of Flash Memory are operated simultaneously at
16 bit mode and even number of chip is applied to lower byte and odd number of chip is applied to upper byte.
At ×8 bit mode, even address and odd address are selected with CEL# and CEH#.

■ FUNCTION DESCRIPTIONS
1. Read Mode
The data in the common can be read with “OE# = VIL ” and “WE# = VIH”. The address is selected with A0-A21.
And CEL# and CEH# select output mode.
2. Standby Mode
– CEL# and CEH# at “VIH” place the card in Standby mode. D0-D15 are placed in a high-Z state independent
of the status “OE#” and “WE#”.
3. Output Disable Mode
– The outputs are disabled with OE# and WE# at “VIH”. D0-D15 are placed in high-Z state.
4. Write Mode
– The card is in Write mode with “OE# = VIH” and “WE# and CE# = VIL”.
– Commands can be written at the Write mode.
– Two types of the Write mode, “WE# control” and “CE# control” are available.
5. Command Definitions
– User can select the card operation by wr iting the specific address and data sequences into the command
register. If incollect address and data are written or improper sequence is done, the card is reseted to read
mode. See “COMMAND DEFINISION TABLE”.
6. Automated Program Capability
– Programming operation can switch the data from “1” to “0”.
– The data is programmed on a byte-by-byte or word-by-word basis.
– The card will automatically provide adequate internally generated programming pulses and verify the pro-
grammed cell margin by writing four bus cycle operation. The card returns to Common Memory Read mode
automatically after the programming is completed.
– Addresses are latched at falling edge of WE# or CE# and data is latched at rising edge of WE# or CE#. The
fourth rising edge of WE# or CE# on the command write cycle begins programming operation.
– W e can check whether a byte (w ord) programming operation is completed successfully b y sequence flug with
BUSY# (except MB98C81013), Data# Polling or Toggle Bit function. See “WRITE OPERATION STATUS”.
– Any commands written to the chip during programming operation will be ignored.
7. Automated Chip Erase Capability
– W e can execute chip erase operation b y 6 bus cycle operation. Chip erase does not require the user to program
the chip prior to erase. Upon executing the Erase command sequence the chip automatically will program
and verify the entire memory for an all zero data pattern prior to electrical erase. The system is not required
to provide any controls or timing during these operations.
– The card returns to Common Memory Read mode automatically after the chip erasing is completed.
– Whether or not chip erase oper ation is completed successfully can be checked b y sequence flug with BUSY#
(except MB98C81013), Data# Polling or Toggle Bit function. See “WRITE OPERATION STATUS”.
– Any commands written to the chip during programming operation will be ignored.

8. Automated Sector Erase Capability
– We can execute the erase operation on any sectors by 6 bus cycle operation.
– A time-out of 50 µs (typ .) from the rising edge of the last Sector Erase command will initiate the Sector Erase
command(s).
– Multiple sectors in a chip can be erased concurrently . This sequence is f ollowed with writes of 30H to addresses
in other sectors desired to be concurrently erased. The time between writes 30H must be less than 50 µs,
otherwise that command will not be accepted. Any command other than Sector Erase or Erase Suspend
during this time-out period will reset the chip to Read mode. The automated sector erase begins after the 50
µs (typ.) time out from the rising edge of WE# pulse for the last Sector Erase command pulse. Whether the
sector erase window is still open can be monitored with D3 and D11.
– Sector Erase does not require the user to program the chip prior to erase. The chip automatically progr ams
“0” to all memory locations in the sector(s) prior to electrical erase. The system is not required to provide any
controls or timing during these operations.
– The card returns to Common Memory Read mode automatically after the chip erasing is completed.
– Whether or not sector erase operation is completed successfully can be checked by sequence flug with
BUSY#, Data# Polling or Toggle Bit function. The sequence flug must be read from the address of the sector
involved in erase operation. See “WRITE OPERATION STATUS”.
9. Erase Suspend
– Erase Suspend command allows the user to interrupt the sector erase operation and then do data reads or
program from or to a non-busy sector in the chip which has the sector(s) suspended erase (only data read is
possible for MB98C81013). This command is applicable only during the sector erase operation (including the
sector erase time-out period after the sector erase commands 30H) and will be ignored if written during the
chip erase or programming operation. Writing this command during the time-out will result in immediate
termination of the time-out period. The addresses are “don’t cares” in wrinting the Erase Suspend or Resume
commands in the chip.
– When the Erase Suspend command is written during a Sector Erase operation, the chip will enter the Erase
Suspend Read mode. User can read the data from other sectors than those in suspention. The read oper ation
from sectors in suspention results D2/D10 toggling except MB98C81013. User can program to non-busy sectors
by writing program commands except MB98C81013.
– A read from a sector being erase suspended may result in invalid data.
10. Intelligent Identifier (ID) Read Mode
– Each common memory can execute an Intelligent Identifier operation, initiated by writing Intelligent ID com-
mand (90H). Following the command write, a read cycle from address 00H retrieves the manufacture code,
and a read cycle from address 01H returns the device code as follows. To terminate the operation, it is
necessary to write Read/Reset command.
11. Hardware Reset (not applied for MB98C81013)
– The Card may be reset by driving the RESET# pin to VIL. The RESET# pin must be kept High (VIL) for at
least 500 ns. Any operation in progress will be terminated and the card will be reset to the read mode 20 µs
after the RESET# pin is driven Low. If a hardware reset occurs during a program operation, the data at that
particular location will be indeterminate.
– When the RESET# pin is Low and the internal reset is complete, the Card goes to standb y mode and cannot
be accessed. Also, note that all the data output pins are High-Z for the duration of the RESET# pulse. Once
the RESET# pin is taken high, the Card requires 500 ns of wake up time until outputs are v alid for read access.
– If hardware reset occurs during a erase operation, there is a possibility that the erasing sector(s) cannot be
used.

12. Data Protection
– The card has WP (Write Protect) switch for write lockout.
– To avoid initiation of a write cycle during V
less than 3.2 V. If VCC < VLKO, the command register is disabled and all internal program/erase circuits are
disabled.
Under this condition the device will reset to the read mode. Subsequent writes will be ignored until the VCC
level is greater than VLKO.It is the users responsibility to ensure that the control pins are logically correct to
prevent unintentional writes when VCC is above 3.2 V.
– If VCC would be less than VLKO during program/erase operation, the operation will stop. And after that, the
operation will not resume even if VCC returns recommended voltage le vel. Therefore , program command must
be written again because the data on the address interrupted program operation is invalid. And regarding
interrupting erase operation, there is possibility that the erasing sector(s) cannot be used.
– Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# will not initiate a write cycle.
CC power-up and power-down, a write cycle is locked out for VCC
