DESCRIPTION:
Maxwell Technologies’ 7206F high speed FIFO microcircuit
features a greater than 100 krad (Si) total dose tolerance,
depending upon space mission. It is organized such that the
data is read in the same sequential order that it was written.
Full and Empty flags are provided to prevent overflow and
underflow. The expansion logic allows unlimited expansion
capability in work size and depth with no timing penalties. Twin
address pointers automatically generate internal read and
write addresses, and automatically increment with the write
and read pin. The 7206F 9-bits wide data are used in data
communications applications where a parity bit for error
checking is necessary. The retransmit capability allows the
read pointer to be reset to its initial position without affecting
the write pointer.
Maxwell Technologies' patented R
AD-PAK® packaging technol-
ogy 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, R
AD-PAK provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
