Silicon Storage Technology (SST) Inc. has introduced its Multi-Purpose Flash Plus (MPF+) product family that follows the Multi-Purpose Flash (MPF) product line. Developed using the company's 0.18?m self-aligned SuperFlash technology, the MPF+ family includes densities of 16Mb, 32Mb, and 64Mb, and is suitable for use in cellphones, set-top boxes, cable and DSL modems, MP3 players, industrial equipment, and other networking products.

The four new features of the product family are Erase Suspend/Erase Resume, Boot Block Write-Protection, Security ID, and Hardware Reset. The Erase Suspend/Erase Resume feature allows an erase operation to be suspended so that other more time-critical operations can be performed before the erase operation is resumed.

The Boot Block Write-Protection feature allows the boot block area of the flash to be protected by a write-protect pin, giving the most important portion of the code an added level of protection from attacks by hackers and viruses, while the Security ID feature offers two 128-bit, one-time programmable registers. The Hardware Reset feature enables system designers to easily reset the entire flash device along with other system devices.

With chip erase operations 1,000 times faster than conventional flash, users can erase their flash devices during manufacturing in 40ms instead of the one or more minutes typical with most flash alternatives. As for in-system programming, individual sectors can be erased 50 to 100 times faster than conventional flash devices.
