24AA52/24LCS52

2K 2.2V I²C^™Serial EEPROM with Software Write-Protect

Device Selection Table

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

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 A

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, DFN and TDFN packages.
