a shorter erase time; therefore, the total energy con-

sumed during any Erase or Program operation is less

than alternative flash technologies.

These devices also improve flexibility while lowering

the cost for program, data, and configuration storage

applications. The SuperFlash technology provides

fixed Erase and Program times, independent of the

number of Erase/Program cycles that have occurred.

Therefore, the system software or hardware does not

have to be modified or de-rated as is necessary with

alternative flash technologies, whose Erase and Pro-

gram times increase with accumulated Erase/Program

cycles.

The SST38VF6401B/6402B/6403B/6404B also offer

flexible data protection features. Applications that

require memory protection from program and erase

operations can use the Boot Block, Individual Block

Protection, and Advanced Protection features. For

applications that require a permanent solution, the Irre-

versible Block Locking feature provides permanent

protection for memory blocks.

To meet high-density, surface mount requirements, the

SST38VF6401B/6402B/6403B/6404B

devices

are

offered in 48-lead TSOP and 48-ball TFBGA packages.

See Figures 2-1 and 2-2 for pin assignments and Table

2-1 for pin descriptions.
