GENERAL DESCRIPTION
The AS58LC1001 is a 1 Megabit CMOS Electrically Erasable
Programmable Read Only Memory (EEPROM) organized as 131, 072
x 8 bits. The AS58LC1001 is capable or in system electrical Byte and
Page reprogrammability.
The AS58LC1001 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 AS58LC1001 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 AS58LC1001 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.
*NOTE: Package lid is connected to ground (Vss). 2-sided shielding
provided via a Tungsten lid and a Tungsten slug on the underside of
package. 6.5X typ. TID boost due to shielding. (Geostationary orbit) Proven
typ. total dose 40K to 100K RADS. Contact factory for more information.
Micross can perform TID lot testing.

DATA PROTECTION
FUNCTIONAL DESCRIPTION
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 AS58LC1001 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 AS58LC1001
to the Non-Protection mode, for normal operation.
3. Software Data Protection
To protect against unintentional programming caused
by noise generated by external circuits, AS58LC1001 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.
