DESCRIPTION

The Microchip Technology Inc. 24AA164 is a cascad-

able 16K bit Electrically Erasable PROM. The device is

organized as eight blocks of 256 x 8-bit memory with a

2-wire serial interface. Low voltage design permits

operation down to 1.8 volts (end-of-life voltage for most

popular battery technologies) with standby and active

currents of only 5 µA and 1 mA respectively. The

24AA164 also has a page-write capability for up to 16

bytes of data.The 24AA164 is available in the standard

8-pin DIP and 8-lead surface mount SOIC packages.
