Description  
Device Selection Table  
The Microchip Technology Inc. 24AA024/24LC024/  
24AA025/24LC025 is a 2 Kbit Serial Electrically  
Erasable PROM with a voltage range of 1.8V to 5.5V.

The device is organized as a single block of 256 x 8-bit  
memory with a 2-wire serial interface. Low current  
design permits operation with typical standby and  
active currents of only 1 µA and 1 mA, respectively.  
The device has a page write capability for up to 16  
bytes of data. Functional address lines allow the  
connection of up to eight 24AA024/24LC024/  
24AA025/24LC025 devices on the same bus for up to  
16K bits of contiguous EEPROM memory. The device  
is available in the standard 8-pin PDIP, 8-pin SOIC  
(150 mil), TSSOP and MSOP packages.
