The Microchip Technology Inc. 24AA256/24LC256/  
24FC256 (24XX256*) is a 32K x 8 (256 Kbit) 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 also has a page write capability of up to 64  
bytes of data. This device is capable of both random  
and sequential reads up to the 256K boundary.  
Functional address lines allow up to eight devices on  
the same bus, for up to 2 Mbit address space. This  
device is available in the standard 8-pin plastic DIP,  
SOIC, SOIJ, TSSOP, MSOP, DFN and TDFN pack-  
ages. The 24AA256 is also available in the 8-lead Chip  
Scale package.  
Note 1: 100 kHz for VCC < 2.5V.  
2: 400 kHz for VCC < 2.5V.  
Features:  
• Single Supply with Operation Down to 1.7V for  
24AA256 and 24FC256 Devices, 2.5V for  
24LC256 Devices  
• Low-Power CMOS Technology:  
- Read current: 400 uA max. at 5.5V, 400 kHz  
- Standby current: 1 uA max. at 3.6V, I-temp  
• 2-Wire Serial Interface, I2CCompatible  
• Cascadable up to Eight Devices  
• Schmitt Trigger Inputs for Noise Suppression  
• Output Slope Control to Eliminate Ground Bounce  
• 100 kHz and 400 kHz Clock Compatibility  
• Page Write Time 5 ms Max.
