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.
