DESCRIPTION

•

Maxwell Technologies’ 79LV0408 multi-chip mod-

ule (MCM) memory features a greater than 100

krad (Si) total dose tolerance, depending upon

space mission. Using Maxwell Technologies’ pat-

ented radiation-hardened RAD-PAK® MCM packag-

ing technology, the 79LV0408 is the first radiation-

hardened 4 Megabit MCM EEPROM for space

applications. The 79LV0408 uses four 1 Megabit

high-speed CMOS die to yield a 4 Megabit product.

The 79LV0408 is capable of in-system electrical

Byte and Page programmability. It has a 128 bytes

Page Programming function to make its erase and

write operations faster. It also features Data Polling

and a Ready/Busy signal to indicate the completion

of erase and programming operations. In the

79LV0408, hardware data protection is provided

with the RES pin, in addition to noise protection on

the WE signal. Software data protection is imple-

mented using the JEDEC optional standard algo-

rithm.

• Four 128k x 8-bit EEPROMs MCM

• RAD-PAK® radiation-hardened against natural

space radiation

• Total dose hardness:

- > 100 krad (Si), depending upon space mis-

sion

• Excellent Single event effects @ 25°C

- SEL > 120 MeV cm²/mg (Device)

- SEU > 85 MeV cm²/mg(Memory Cells)

- SEU > 18 MeV cm²/mg (Write Mode)

- SET > 40 MeV cm²/mg (Read Mode)

• Package

- 40 Pin RAD-PAK® Flat Pack

- 40 Pin RAD-PAK® Rad Tolerant Flat Pack

• High speed:

-200 and 250 ns access times available

• Data Polling and Ready/Busy signal

• Software data protection

• Write protection by RES pin

• High endurance

- 10,000 erase/write (Page Mode),

- 10 year data retention

• Page write mode: 1 to 128 byte page

• Low power dissipation

Maxwell Technologies' patented RAD-PAK® packag-

ing technology incorporates radiation shielding in

the microcircuit package. It eliminates the need for

box shielding while providing the required radiation

shielding for a lifetime in orbit or space mission. In

a GEO orbit, the RAD-PAK® package provides

greater than 100 krad (Si) radiation dose tolerance.

This product is available with screening up to Max-

well Technologies self-defined Class K.

- 88 mW/MHz active mode

- 440 µW standby mode
