boundaries 0000h to FFFFh and 10000h to 1FFFFh.  
Functional address lines allow up to four devices on the  
same data bus. This allows for up to 4 Mbits total  
system EEPROM memory. This device is available in  
the standard 8-pin PDIP, SOIC and SOIJ packages.

The Microchip Technology Inc. 24AA1025/24LC1025/  
24FC1025 (24XX1025*) is a 128K x 8 (1024K bit)  
Serial Electrically Erasable PROM, capable of  
operation across a broad voltage range (1.7V to 5.5V).  
It has been developed for advanced, low-power  
applications such as personal communications or data  
acquisition. This device has both byte write and page  
write capability of up to 128 bytes of data.
