FEATURES:
• 128k x 8-bit EEPROM
RAD-PAK® radiation-hardened against natural space radia-
tion
Total dose hardness:
- > 100 krad (Si), depending upon space mission
Excellent Single Event Effects:
- No Latchup > 120 MeV/mg/cm
2
- SEU > 90 MeV/mg/cm
2
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:
- 1 to 128 bytes
Low power dissipation
- 20 mW/MHz active (typical)
- 110 µ W standby (maximum)
DESCRIPTION:
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.
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.
