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 conguration 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 selectable read/write capability of the memory
array in standard I2C 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.
- Commercial
(C):
0°C to +70°C
- Industrial (I)
-40°C to +85°C
