SST Announces Production of Small-Footprint, High-Performance
8-Mbit SPI Serial Flash Memory Device SST25LF080A 8-Mbit Serial
Flash Product Features High-Clock Frequency in an 8-Lead SOIC
Package SUNNYVALE, Calif., April 26 /PRNewswire-FirstCall/ -- SST
(Silicon Storage Technology, Inc.) , a leader in flash memory
technology, today announced production availability of its 8-Mbit
Serial Peripheral Interface (SPI) serial flash memory device, the
SST25LF080A. Based on SST's proprietary, high-performance
SuperFlash technology, the SST25LF080A is the latest addition to
the successful 25 Series of serial flash memory products. Ideal for
such applications as hard disk drives, printers, security systems,
industrial controls, 802.11a/b/g and wired networking equipment,
SST's 8-Mbit serial flash device features a 33-MHz max clock
frequency and a typical standby current of only 8 microamperes,
thus significantly improving performance while lowering power
consumption. The 33-MHz clock frequency has also been extended to
SST's 2-Mbit and 4-Mbit serial flash devices, which are also
currently available in volume production. The company expects to
add the 33-MHz speed option to the 1-Mbit and 512-Kbit serial flash
devices in the second half of 2004. SST's 8-Mbit serial flash
device offers several advantages not available in alternative
solutions, including an Auto Address Increment (AAI) operation and
small sector erase capability. The 8-Mbit serial flash memory
device is offered in a small footprint, 8-pin SOIC package with 200
mils body width. "Our 8-Mbit serial flash memory devices offer an
optimum balance of features, performance and package size for a
variety of applications," said Michael Briner, senior vice
president of SST's Application Specific Product Group. "Delivering
our 8-Mbit serial flash devices in a 33-MHz max clock frequency and
in an 8-pin package enables SST to deliver a high-performance
serial flash solution that helps reduce overall system cost by
saving board space and eliminating costly redesigns with density
migration." SST's serial flash memory products incorporate a
four-wire, SPI-compatible interface. When compared to other
nonvolatile memory interfaces, the SPI- interface serial flash
products use fewer pins to transfer data to and from a system CPU,
thereby creating an overall reduction in board space, power
consumption and cost. Like all of SST's products based on
SuperFlash technology, the SST25LF080A features small sector erase
capability, allowing designers to seamlessly partition code or data
into 4-KByte sectors, resulting in faster write times and an
overall increase in system performance. Because of its low power
consumption and small footprint, the SST25LF080A is an ideal code
storage solution in applications such as hard disk drives, wireless
and networking equipment. SST's 8-Mbit serial flash memory devices
feature a unique AAI fast- programming mode, enabling a reduction
in total flash memory programming time by up to 50 percent when
compared to single-byte programming modes. The AAI program
instruction allows multiple bytes of serial flash memory to be
programmed without re-issuing subsequent addresses and commands
after the first data byte program sequence. As a result, new
programs can be loaded into flash using fewer commands, thus
reducing programming times. This advantage is especially useful
during the manufacturing process, where fast production line
throughput is essential. SST's 25 Series of serial flash memory
products range in density from 512 Kbit to 16 Mbit, all containing
the same footprint, providing customers with a seamless migration
path to higher densities for their systems. This capability allows
designers to create product lines with new levels of functional
flexibility and dramatically lower system costs when compared to
systems using parallel flash products housed in traditional 32-pin
or 48-pin packages. Pricing and Availability The 8-Mbit device
(SST25LF080A) is available now in volume production. Pricing for
the SST25LF080A is $1.70 in 100K unit quantities. For more
