Description
The Microchip Technology Inc. 24AA52/24LCS52
(24XX52*) 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 A
and 1 mA respectively. The 24XX52 also has a page
write capability for up to 16 bytes of data. The 24XX52
is available in the standard 8-pin PDIP, surface mount
SOIC, TSSOP and MSOP packages.

... Device Addressing A control byte is the first byte received following the Start condition from the master device. The first part of the control byte consists of a 4-bit control code which is set to ‘1010’ for normal read and write operations and ‘0110’ for writing to the write-protect register.
