| The 24LCS21 is a 128 x 8-bit dual-mode Serial Electrically Erasable PROM designed to meet the plug-and-play requirements of today’s 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. |
