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.

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

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

with screening up to Class S.
