79C2040B

20 Megabit (512K x 40-Bit)

EEPROM MCM

Logic Diagram

DESCRIPTION:

FEATURES:

Maxwell Technologies’ 79C2040B multi-chip module (MCM)

memory features a greater than 100 krad (Si) total dose toler-

ance, dependent upon orbit. Using Maxwell Technologies’ pat-

ented radiation-hardened R^AD-PAK® MCM packaging

technology, the 79C2040B is the first radiation-hardened 20

megabit MCM EEPROM for space application. The 79C2040B

uses twenty 1 Megabit high speed CMOS die to yield a 20

megabit product. The 79C2040B is capable of in-system elec-

trical byte and page programmability. It has a 128 word page

programming function to make the 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 79C2040B, hardware data protection is provided with

the RES pin, in addition to noise protection on the WE signal

and write inhibit on power on and off. Software data protection

is implemented using the JEDEC optional standard algorithm.

512k x 40-bit EEPROM MCM

•

RAD-PAK® radiation-hardened against natural

space radiation

Total dose hardness:

- >100 krad (Si)

- Dependent upon orbit

•

Excellent Single event effects @ 25^°C

- SEL_TH> 120 MeV cm²/mg (Device)

- SEU_TH> 90 MeV cm²/mg(Memory Cells)

- SEU _TH> 18 MeV cm²/mg (Write Mode)

- SET_TH> 40 MeV cm²/mg (Read Mode)

High endurance

- 10,000 cycles/byte (Page Programming Mode)

- 10 year data retention

•

Page Write Mode: 128 Dword Page

High Speed:

Maxwell Technologies' patented R^AD-PAK® packaging technol-

ogy incorporates radiation shielding in the microcircuit pack-

age. 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, R^AD-PAK® provides greater than 100

krad (Si) radiation dose tolerance. This product is available

with screening up to Maxwell Technologies’ self-defined Class

- 150 and 200 ns maximum access times

Automatic programming

- 10 ms automatic Page/Dword write

Low power dissipation

- 375 mW/MHz active current

- 3. 2 mW standby current
