1CAT24C211-kb Dual Mode Serial EEPROM for VESA™ Plug-and-Play * Catalyst Semiconductor is licensed by Philips Corporation to carry the I2C Bus Protocol.FUNCTIONAL SYMBOLFEATURES■ DDC1TM/DDC2TM interface compliant for monitor identification■ 400 kHz I2C bus compatible*■ 2.5 to 5.5 volt operation■ 16-byte page write buffer■ Hardware write protect■ Low power CMOS technology■ 1,000,000 program/erase cycles■ 100 year data retention■ 8-pin DIP, SOIC, TSSOP, MSOP or TDFNpackages■ Industrial temperature rangeDESCRIPTIONThe CAT24C21 is a 1-kb Serial CMOS EEPROMinternally organized as 128 words of 8 bits each. Thedevice complies with the Video Electronics StandardAssociation s (VESA™), Display Data Channel (DDC™)standards for Plug-and-Play monitors. The transmit-only mode (DDC1™) is controlled by the VCLK clockinput and the bi-directional mode (DDC2™) is controlled© 2004 by Catalyst Semiconductor, Inc.Characteristics subject to change without noticeDoc. No. 1032, Rev. OHALOGENFREETMLEADFREEby the SCL clock input, with both modes sharing acommon SDA input/output (I/O). The transmit-only modeis a read-only mode, while the bi-directional mode is aread and write mode following the I2C protocol. In writemode the CAT24C21 features a 16-byte page writebuffer. The device is available in 8-in DIP, SOIC, TSSOP,MSOP and TDFN packages.PIN FUNCTIONSPin Name FunctionNC No ConnectSDA Serial Data/AddressSCL Serial Clock (bi-directional mode)VCLK Serial Clock (transmit-only mode)VCCPower SupplyVSSGroundPIN CONFIGURATIONDIP Package (P, L)SOIC Package (J, W)TSSOP Package (U, Y)MSOP Package (R, Z)VCCSCLSDA12348765VSSVCLKNCNCNCTDFN Package (RD4, ZD4)3 mm x 3 mmTop View8765VCCVCLKSCLSDAVSS1234NCNCNC87651234NCNCNCVSSVCCVCLKSCLSDAVCCVCLKSCLSDA12348765VSSNCNCNCVCCVCLKSCLSDA12348765VSSNCNCNCVCCVSSSDASCLVCLKCAT24C21
