This device provides another function to determine the internal programming cycle. If the EEPROM is set to read mode
during the internal programming cycle, I/O6 will charge from "1" to "0" (toggling) for each read. When the internal programming cycle is finished, toggling of I/O6 will stop and the device can be accessible for next read or program.

FUNCTIONAL DESCRIPTION
Automatic Page Write
Page-mode write feature allows 1 to 128 bytes of data to be
written into the EEPROM in a single write cycle. Following
the initial byte cycle, an additional 1 to 128 bytes can be written in the same manner. Each additional byte load cycle must
be started within 30µs from the preceding falling edge of WE\
or CE\. When CE\ or WE\ is kept high for 100µs after data
input, the EEPROM enters write mode automatically and the
input data are written into the EEPROM.
RDY/Busy\ Signal
RDY/Busy\ signal also allows status of the EEPROM to be
determined. The RDY/Busy\ signal has high impedance except in write cycle and is lowered to VOL after the first write
signal. At the end of write cycle, the RDY/Busy\ signal changes
state to high impedance.
RES\ Signal
When RES\ is low, the EEPROM cannot be read or programmed. Therefore, data can be protected by keeping RES\
low when VCC is switched. RES\ should be high during read
and programming because it doesn't provide a latch function.
See timing diagram below.
DATA\ Polling
DATA\ polling allows the status of the EEPROM to be determined. If EEPROM is set to read mode during the write cycle,
an inversion of the last byte of data to be loaded outputs from
I/O's 7, 15, 23, and 31 to indicate that the EEPROM is performing a write operation.

WE\, CE\ Pin Operation
During a write cycle, address are latched by the falling edge
of WE\ or CE\, and data is latched by the rising edge of WE\
or CE\.
Write/Erase Endurance and Data Retention Time
The endurance is 104 cycles in case of the page programming
and 103 cycles in case of the byte programming (1% cumulative failure rate). The data retention time is more than 10
years when a device is page-programmed less than 104 cycles.
RDY/Busy\ SIGNAL
RDY/Busy\ signal also allows status of the EEPROM to
be determined. The RDY/Busy\ signal has high impedance
except in write cycle and is lowered to VOL after the first write
signal. At the end of the write cycle, the RDY/Busy\ signal
changes state to high impedance. This allows many 58C1001
devices RDY/Busy\ signal lines to be wired-OR together.
has a noise cancellation function that cuts noise if its width is
20ns or less in program mode.
Be careful not to allow noise of a width more than
20ns on the control pins. See Diagram 1 below.
2. Data Protection at VCC On/Off
When VCC is turned on or off, noise on the control
pins generated by external circuits (CPU, etc.) may act as a
trigger and turn the EEPROM to program mode by mistake.
To prevent this unintentional programming, the EEPROM must
be kept in an unprogrammable state while the CPR is in an
unstable state.
NOTE: The EEPROM should be kept in
unprogrammable state during VCC on/off by using CPU RESET signal. See the timing diagram below.
End O
f Life
PROGRAMMING/ERASE
The 58C1001 does NOT employ a BULK-erase function.
The memory cells can be programmed ‘0’ or ‘1’. A write cycle
performs the function of erase & write on every cycle with
the erase being transparent to the user. The internal erase data
state is considered to be ‘1’. To program the memory array
with background of ALL 0’s or All 1’s, the user would
program this data using the page mode write operation to
program all 1024 128-byte pages.

Data Protection Cont.
a. Protection by RES\
The unprogrammable state can be realized by the
CPU's reset signal inputs directly to the EEPROM's RES pin.
RES should be kept VSS level during VCC on/off.
The EEPROM brakes off programming operation
when RES becomes low, programming operation doesn't finish correctly in case that RES falls low during programming
operation. RES should be kept high for 10ms after the last
data inputs. See the timing diagram below.
3. Software data protection
To prevent unintentional programming, this device
has the software data protection (SDP) mode. The SDP is
enabled by inputting the 3 bytes code and write data in
Chart 1. SDP is not enabled if only the 3 bytes code is input.
To program data in the SDP enable mode, 3 bytes code must
be input before write data. This 4th cycle during write is
required to initiate the SDP and physically writes the address
and data. While in SDP the entire array is protected in which
writes can only occur if the exact SDP sequence is
re-executed or the unprotect sequence is executed.
The SDP is disabled by inputting the 6 bytes code in
Chart 2. Note that, if data is input in the SDP disable cycle,
data can not be written.
The software data protection is not enabled at the
shipment.
NOTE: These are some differences between ASI's
and other company's for enable/disable sequence of software
data protection. If these are any questions, please contact ASI.
