Description

Maxwell Technologies' 29F0408 high-performance flash mem-ory. The 29F0408 is a 4M (4,194,304) x 8-bit NAND Flash Memory with a spare 128K (131,072) x 8-bit. A program oper-ation programs the 528-byte page in 250 µ s and an erase operation can be performed in 2 ms on an 8K-byte block. Data within a page can be read out at 50 ns cycle time per byte.The on-chip write controller automates all program and erase functions, including pulse repetition, where required, and inter-nal verify and margining of data. Even write-intensive systems can take advantage of the 29F0408's extended reliability of 1,000,000 program/erase cycles by providing either ECC (Error Correction Code) or real time mapping-out algorithm. These algorithms have been implemented in many mass stor-age applications. The spare 16 bytes of a page combined with the other 512 bytes can be utilized by system-level ECC. The 29F0408 is an optimum solution for large non-volatile storage applications such as solid state storage, digital voice recorder, digital still camera and other portable applications requiring nonvolatility.

Maxwell Technologies' patented RAD-PAK^® packaging technol-ogy incorporates radiation shielding in the microcircuit pack-age. Capable of surviving in space environments, the 29F0408 is ideal for satellite, spacecraft, and space probe missions. It is available with packaging and screening up to Class S.
