SPI serial EEPROMsMicrochip Technology Inc. has expanded its serial peripheral interface (SPI) serial EEPROM line with a pair of 256Kb devices that can achieve speeds of up to 10MHz.

The 25AA256 is available in a 1.8V to 5.5V voltage range, and the 25LC256 has a 2.2V to 5.5V voltage range. The devices are offered in both the industrial temperature range of -40C to 85C and extended temperature range of -40C to 125C. The SPI bus is a fast-growing segment of the serial EEPROM market. Designers are choosing SPI-based devices for speed advantages and easy connections with microcontrollers.

"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 source for current designs."

The devices features 200-year data retention and endurance of 1 million erase/write cycles. They are offered in 0.9 millimeter, DFN packaging for applications with limited space requirements. Standard packaging is also provided and includes TSSOP, PDIP and SOIC.

Microchip's SEEVAL 32 serial EEPROM designer's kit supports the new devices. The company is also offering free of charge the Total Endurance software for modeling and designing serial EEPROM applications.

Both the 25AA256 and 25LC256 are sampling, with volume production scheduled for next month (August 2005). In 10,000-unit quantities, the devices are $1.63 each.
