Ordering Information
General Description
The AM24LC21 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 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. The AM24LC21 is available in a
standard 8-pin PDIP and SOP package in both
commercial and industrial temperature ranges.
