The 24LCS21 is a 128 x 8-bit dual-mode Serial Electrically Erasable PROM designed to meet the plug-and-play requirements of todays advanced monitors. The 24LCS21 represents a simple, low-cost route to meeting the stringent standards for monitor identification since it implements both the DDCI and DDC2 operating modes as defined by the Video Electronics Standards Association. The 24LCS21 features a software enabled hardware write protection pin which enables the user to write-protect the entire memory contents. Other features include an improved noise filter, a 2-wire serial interface bus (I2C compatible), both commercial and industrial temperature ranges, and a wide voltage range (2.5V to 5.5V). The 24LCS21 is available in standard 8-pin PDIP and SOIC packages.
