The Austin Semiconductor, Inc. AS58C1001 is a 1 Megabit CMOS
Electrically Erasable Programmable Read Only Memory (EEPROM)
organized as 131, 072 x 8 bits. The AS58C1001 is capable or in
system electrical Byte and Page reprogrammability.
The AS58C1001 achieves high speed access, low power
consumption, and a high level of reliability by employing advanced
MNOS memory technology and CMOS process and circuitry
technology and CMOS process and circuitry technology.
This device has a 128-Byte Page Programming function to make its
erase and write operations faster. The AS58C1001 features Data
Polling and a Ready/Busy signal to indicate completion of erase and
programming operations.
This EEPROM provides several levels of data protection.
Hardware data protection is provided with the RES pin, in addition to
noise protection on the WE signal and write inhibit during power on
and off. Software data protection is implemented using JEDEC
Optional Standard algorithm.
The AS58C1001 is designed for high reliability in the most
demanding applications. Data retention is specified for 10 years and
erase/write endurance is guaranteed to a minimum of 10,000 cycles in
the Page Mode.

FUNCTIONAL DESCRIPTION
AS58C1001
DATA PROTECTION
To protect the data during operation and power on/off, the
AS58C1001 has:
1. Data protection against Noise on Control Pins (CE\, OE\,
WE\) during Operation. During readout or standby, noise on
the control pins may act as a trigger and turn the EEPROM to
programming mode by mistake. To prevent this phenomenon,
the AS58C1001 has a noise cancellation function that cuts noise
if its width is 20ns or less in programming mode. Be careful not
to allow noise of a width of more than 20ns on the control pins.
AUTOMATIC PAGE WRITE
The Page Write feature allows 1 to 128 Bytes of data to be
written into the EEPROM in a single cycle and allows the undefined data within 128 Bytes to be written corresponding to
the undefined address (A0 to A6). Loading the first Byte of
data, the data load window of 30μs opens for the second. In the
same manner each additional Byte of data can be loaded within
30μs. In case CE\ and WE\ are kept high for 100μs after data
input, the EEPROM enters erase and write automatically and
only the input data can be written into the EEPROM. In Page
mode the data can be written and accessed 104 times per page,
and in Byte mode 103 times per Byte.
DATA\ POLLING
Data\ Polling allows the status of the EEPROM to be determined. If the EEPROM is set to Read mode during a Write
cycle, and inversion of the last Byte of data to be loaded outputs from I/O, to indicate that the EEPROM is performing a
Write operation.
WRITE PROTECTION
(1) Noise protection: Noise on a write cycle will not act as
a trigger with a WE\ pulse of less than 20ns.
(2) Write inhibit: Holding OE\ low, WE\ high or CE\ high,
inhibits a write cycle during power on/off.
WE\ AND CE\ PIN OPERATION
During a write cycle, addresses 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
The endurance with page programming is 104 cycles (1%
cumulative failure rate) and the data retention time is more than
10 years when a device is programmed less than 104 cycles.

FUNCTIONAL DESCRIPTION (continued)

DATA PROTECTION (continued)
2. Data protection at Vcc on/off.
When RES\ is low, the EEPROM cannot be erased and
programmed. Therefore, data can be protected by keeping
RES\ low when Vcc is switched. RES\ should be high during
programming because it does not provide a latch function.
When Vcc is turned on or off, noise on the control pins
generated by external circuits (CPU, etc.) may turn the
EEPROM to programming mode by mistake. To prevent
this unintentional programming, the EEPROM must be kept
in an unprogrammable, standby or readout state by using a
CPU reset signal to RES\ pin.
In addition, when RES\ is kept high at Vcc on/off timing,
the input level of control pins (CE\, OE\, WE\) must be held
as CE\=Vcc or OE\=LOW or WE\=Vcc level.

The Software data protection mode can be cancelled by
inputting the following 6 Bytes. This changes the AS58C1001
to the Non-Protection mode, for normal operation.
3. Software Data Protection
To protect against unintentional programming caused by
noise generated by external circuits, AS58C1001 has a
Software data protection function. To initate Software data
protection mode, 3 bytes of data must be input, followed by
a dummy write cycle of any address and any data byte. This
exact sequence switches the device into protection mode.
