Description:

The Microchip Technology Inc. 24AA024/24LC024/
24AA025/24LC025 is a 2Kbit Serial Electrically 
Erasable PROM with a voltage range of 1.8V to 5.5V. 
The device is organized as a single block of 256 x8-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, 2x3 DFN and MSOP packages.
