DESCRIPTION  
The Microchip Technology Inc. 24LC024/24LC025 is a  
2K bit Serial Electrically Erasable PROM with a voltage  
range of 2.5V 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 10 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 24LC024/24LC025  
devices on the same bus for up to 16K bits of contigu-  
ous EEPROM memory. The device is available in the  
standard 8-pin PDIP, 8-pin SOIC (150 mil), and TSSOP  
packages.
