DESCRIPTION
The Microchip Technology Inc. 24LCS21 is a
128 x 8-bit dual-mode Electrically Erasable PROM.
This device is designed for use in applications requiring
storage and serial transmission of configuration and
control information. Two modes of operation have been
implemented: Transmit Only Mode and bi-directional
Mode. Upon power-up, the device will be in the Transmit
Only Mode, sending a serial bit stream of the entire
memory array contents, clocked by the VCLK pin. A
valid high to low transition on the SCL pin will cause the
device to enter the bi-directional Mode, with byte select-
able read/write capability of the memory array in stan-
dard I
C protocol.
The 24LCS21 also enables the user to write-protect the
entire memory contents using its write-protect pin. The
24LCS21 is available in a standard 8-pin PDIP and
SOIC package in both commercial and industrial
temperature ranges.
