Microchip's 25xx010A, 25xx020A and 25xx040A are claimed to be the world's first SPI serial EEPROMs in a miniature, SOT-23 package. The devices extend the company's SPI serial EEPROM product line into high-speed (10 MHz), low-density (1-2 Kbit) applications. In addition to the SOT-23, they are available in the popular 2 x 3 mm DFN package and all standard packages. Developed using Microchip's PMOS electrically erasable cell (PEEC) technology they provide data retention for up to 200 years and offer well over one million erase/write cycles in most applications.
The 25AA010A and 25LC010A EEPROMs provide 1 Kbit of memory density, the 25AA020A and 25LC020A provide 2 Kbit, and the 25AA040A and 25LC040A provide 4 Kbit, all capable of speeds up to 10 MHz. In addition to the 6-pin SOT-23 and 8-pin DFN packages, all of the new memories are available in 8-pin SOIC, TSSOP, MSOP and PDIP packages.
Microchip's SEEVAL 32 Serial EEPROM Designer's Kit supports development using these EEPROMs.
