24LCS52/ST Datasheet



The Microchip Technology Inc. 24LCS52/ST 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 downto 1.8V, with standby and active currents of only 1 µA and 1 mA respectively. The 24LCS52/ST also has a page write capability for up to 16 bytes of data. The 24LCS52/ST is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP and MSOP packages. 24LCS52/ST 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
