24AA52/24LCS52  
2K 2.2V I2C™ Serial EEPROM with Software Write-Protect  
Features:  
Description:  
• Single supply with operation down to 1.8V  
• Low-power CMOS technology:  
The Microchip Technology Inc. 24AA52/24LCS52  
(24XXX52*) is a 2 Kbit Electrically Erasable PROM  
capable of operation across a broad voltage range  
(1.8V to 5.5V). This device has a software write-protect  
feature for the lower half of the array, as well as an  
external pin that can be used to write-protect the entire  
array. The software write-protect feature is enabled by  
sending the device a special command. Once this  
feature has been enabled, it cannot be reversed. In  
addition to the software protect feature, there is a WP  
pin that can be used to write-protect the entire array,  
regardless of whether the software write-protect  
register has been written or not. This allows the system  
designer to protect none, half, or all of the array,  
depending on the application. The device is organized  
as one block of 256 x 8-bit memory with a 2-wire serial  
interface. Low-voltage design permits operation down  
to 1.8V, with standby and active currents of only 1 μA  
and 1 mA, respectively. The 24XXX52 also has a page  
write capability for up to 16 bytes of data. The 24XXX52  
is available in the standard 8-pin PDIP, surface mount  
SOIC, TSSOP, MSOP and DFN packages.  
- 1 mA active current, typical  
- 1 μA standby current, typical (I-temp)  
• Organized as 1 block of 256 bytes (256 x 8)  
• Software write protection for lower 128 bytes  
• Hardware write protection for entire array  
• 2-wire serial interface bus, I2C™ compatible  
• Schmitt Trigger inputs for noise suppression  
• Output slope control to eliminate ground bounce  
• 100 kHz (24AA52) and 400 kHz (24LCS52)  
compatibility  
• Self-timed write cycle (including auto-erase)  
• Page write buffer for up to 16 bytes  
• ESD protection > 4,000V  
• 1,000,000 erase/write cycles  
• Data retention > 200 years  
• 8-lead PDIP, SOIC, TSSOP, MSOP and DFN  
packages  
• Pb-free finishes available

• Available for extended temperature ranges:
