Micron Technology today introduced the highest-density Serial
Peripheral Interface (SPI) NOR memory available, launching 1 gigabit
(Gb), 512 megabit (Mb) and 256Mb products in both 1.8V and 3V power supply voltages.
Employing 65nm process technology, the N25Q product family offers
the highest-speed quad I/O in the industry and a full set of
advanced features and small packages that improve overall system
performance and time-to-market in networking, set-top boxes,
automotive and a wide range of industrial, computing and consumer
applications.
"In addition to providing the world?s highest-density,
high-performance SPI NOR memory, the N25Q family provides package
and software compatibility across densities, from 32Mb to 1Gb," said
Tom Eby, Vice President and General Manager of Micron's Embedded
Solutions Group. "When combined with industrial temperature range,
1.8V and 3.0V power supply options, and the longevity of Micron's
PLP program, this product family provides an ideal solution for the
SPI NOR needs of the embedded market."
Micron's N25Q SPI NOR family offers the following features:
- Multiple I/O protocol ? single SPI, dual SPI (DSPI) and quad SPI
(QSPI)
- Double transfer rate (DTR) feature enhances read performance
- 54MB/s read transfer rate at 108 MHz clock
- Footprint compatibility across the entire line, from 32Mb up to
1Gb
- 500KB/s program speed
- 4 bytes of address mode supported for high-density range
requirements (128Mb+)
- Execute-in-place (XIP) capability supports code execution directly
from the flash, reducing RAM usage and overall cost
- Nonvolatile configuration register delivers maximum flexibility in
application usage models
"The NOR market continues to trend toward SPI devices, with analysts
estimating that more than half of NOR revenue will be SPI by 2013,"
said Eby.
Sampling now, Micron's 1Gb, 512Mb and 256Mb devices are available
through Micron's sales channels. |
