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. 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.
