New 25XX256 High-Density SPI Serial EEPROMs Debut

CHANDLER, Ariz., — Microchip Technology Inc., has expanded its SPI™ serial EEPROM product line with two high-density (256 Kbit), high-speed (up to 10 MHz) devices. The 25AA256 and 25LC256 serial EEPROMs feature Microchip's industry-leading endurance and reliability along with Microchip's commitment to consistent on-time delivery.

"Microchip is launching high-density SPI products at the right time, as worldwide customer demand for these devices is outstripping available supply from other vendors," said Barry Blixt, senior product marketing engineer for the Memory Products Division at Microchip. "Microchip is committed to providing appropriate production capacity during all semiconductor industry cycles. This gives engineers peace of mind, making our 25AA256 and 25LC256 an ideal solution for new designs and an excellent second source for current designs."

The SPI bus is a fast-growing segment of the serial EEPROM market. Designers choose SPI-based devices for speed advantages and easy connections with microcontrollers. The 25AA256 is available in a 1.8V - 5.5V voltage range, and the 25LC256 has a 2.5V - 5.5V voltage range. Both industrial-temperature grade (-40°C to +85°C) and extended-temperature grade (-40°C to +125°C) versions are available.

These devices feature industry-leading reliability with 200-year data retention and endurance of one million erase/write cycles. They are offered in the extremely low-profile (0.9 millimeter) DFN package for applications with limited space requirements. Standard packaging is also provided, including TSSOP, PDIP and SOIC.

The new SPI devices are supported by Microchip’s SEEVAL® 32 Serial EEPROM Designer’s Kit. This low-cost development system enables designers to quickly and easily develop robust and reliable serial EEPROM-based applications, while significantly reducing the time required for system integration and hardware/software debug.

Microchip also offers the Total Endurance™ software, a powerful and easy-to-use tool for modeling and designing serial EEPROM applications. Available for free from Microchip’s Web site, this modeling software takes the guesswork out of determining the life of a serial EEPROM device in an embedded design. Design trade-off analysis that formerly consumed days or weeks can now be accomplished in minutes with a level of accuracy that delivers a truly robust design.

Sampling for the 25AA256 and 25LC256 is available today, and volume production is scheduled for August 2005. Pricing for either device is $1.63 each in 10,000 unit quantities.
