DESCRIPTION:
• 128k x 8-bit EEPROM
• RAD-PAK® radiation-hardened against natural space radia-
tion
Maxwell Technologies’ 28C011T high-density 1 Megabit (128K
x 8-Bit) EEPROM microcircuit features a greater than 100
krad (Si) total dose tolerance, depending upon space mission.
The 28C011T is capable of in-system electrical byte and page
programmability. It has a 128-byte page programming function
to make its erase and write operations faster. It also features
data polling and a Ready/Busy signal to indicate the comple-
tion of erase and programming operations. In the 28C010T,
hardware data protection is provided with the RES pin, in addi-
tion 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.
• Total dose hardness:
- > 100 krad (Si), depending upon space mission
• Excellent Single Event Effects:
- No Latchup > 120 MeV/mg/cm2
- SEU > 90 MeV/mg/cm2 read mode
• Package:
- 32-pin RAD-PAK® flat package
- 32-pin Rad-Tolerant flat package
- JEDEC-approved byte-wide pinout
• High speed:
- 120, 150, and 200 ns maximum access times available
• High endurance:
- 10,000 erase/write (in Page Mode),
- 10 year data retention
• Page write mode:
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.
- 1 to 128 bytes
• Low power dissipation
- 20 mW/MHz active (typical)
- 110 µW standby (maximum)
