FEATURES:  
DESCRIPTION:  
• RAD-PAK® radiation-hardened against natural space radia-  
tion  
Total dose hardness:  
Maxwell Technologies’ 28C256T high density 256k-bit  
EEPROM microcircuit features a greater than 100 krad (Si)  
total dose tolerance, depending upon space mission. The  
28C256T is capable of in-system electrical byte and page pro-  
grammability. It has a 64-Byte page programming function to  
make its erase and write operations faster. It also features  
data polling to indicate the completion of erase and program-  
ming operations.  
- > 100 Krad (Si), dependent upon space mission  
• Excellent Single Event Effects:  
- SEL LET: > 120 MeV/mg/cm2  
TH  
- SEUTH LET (read mode): > 90 MeV/mg/cm2  
- SEUTH LET (write mode): > 18 MeV/mg/cm2  
• Package:  
- 28 pin RAD-PAK® flat pack  
- 28 pin RAD-PAK® DIP  
- JEDEC approved byte wide pinout  
High Speed:  
- 120, 150 ns maximum access times available  
High endurance:  
Maxwell Technologies' patented RAD-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, RAD-PAK provides greater than 100  
krad (Si) radiation dose tolerance. This product is available  
with screening up to Class S.  
- 10,000 erase/write (in Page Mode), 10-year data  
retention  
• Page Write Mode:  
- 1 to 64 bytes  
Low power dissipation:  
- 15 mA active current (cycle = 1 µs)  
- 20 µA standby current (CE = V )
