Description: 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. Features: • Single Supply with Operation Down to 1.8V • Low-Power CMOS Technology: - 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, DFN and TDFN Packages • Pb-Free Finishes Available • Available for Extended Temperature Ranges: - Industrial (I): -40°C to +85°C
