Description:

Block Diagram

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 informa-

tion. Two modes of operation have been implemented:

Transmit-Only mode and Bidirectional 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 Bidirectional 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.
