DESCRIPTION
The Microchip Technology Inc. 24LCS52 is a 2K bit
Electrically Erasable PROM capable of operation
across a broad voltage range (2.5V 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 spe-
cial command, and once this feature has been enabled,
it cannot be reversed. In addition to the software pro-
tect feature, there is a WP pin that can be used to write
protect the entire array, regardless of whether the soft-
ware 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 a single block of 256 x 8-bit memory with
a 2-wire serial interface. Low voltage design permits
operation down to 2.5 volts with typical standby and
active currents of only 5
μ
A and 1 mA respectively. The
device has a page-write capability for up to 16 bytes of
data. The device is available in the standard 8-pin DIP,
8-pin SOIC and TSSOP packages.
