Microchip's latest Microwire serial EEPROMs are available in 6-lead SOT-23 packages and support densities from 1 to 4Kbit.

Using Microchip's advanced PMOS electrically erasable cell (PEEC) process technology, Microchip claims the 93XX46A/B, 93XX56A/B and 93XX66A/B devices are the world's smallest serial EEPROMs in a standard package.

The 6-lead SOT-23 package has a surface area of only 8.26 mm2 - 72% smaller than the popular 8-lead narrow SOIC package and 56% smaller than the 8-lead TSSOP package, and a height of only 1.2 mm - 23% lower than the SOIC package, making these devices ideal for portable and handheld applications.

Microchip's dedicated 8 and 16bit word Microwire devices made this package offering possible by eliminating the word organisation (ORG) pin function and providing full functionality using only 6 pins.

The 93LCXXA/B series supports operating voltages down to 2.5V, active current of 1mA and standby current of 1uA.

For battery-powered applications with even lower voltage requirements, the 93AAXXA/B versions can operate down to 1.8V.

If higher voltages are required with a higher reset power-down voltage, the 93CXXA/B devices are designed to operate in standard 5V designs.
