1 / 14 page © Semiconductor Components Industries, LLC, 2009 September, 2009 − Rev. 16 1 Publication Order Number: CAT24C21/D CAT24C21 1 kb Dual Mode Serial EEPROM for VESA t “Plug-and-Play” Description The CAT24C21 is a 1 kb Serial CMOS EEPROM internally organized as 128 words of 8 bits each. The device complies with the Video Electronics Standard Association’s (VESA ™), Display Data Channel (DDC ™) standards for “Plug−and−Play” monitors. The “transmit−only” mode (DDC1 ™) is controlled by the VCLK clock input and the “bi−directional” mode (DDC2 ™) is controlled by the SCL clock input, with both modes sharing a common SDA input/output (I/O). The transmit−only mode is a read−only mode, while the bi−directional mode is a read and write mode following the I2C protocol. In write mode the CAT24C21 features a 16−byte page write buffer. The device is available in 8−lead DIP, SOIC, TSSOP, MSOP and TDFN packages. Features • DDC1t/DDC2t 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 • Industrial Temperature Range • 8−lead DIP, SOIC, TSSOP, MSOP or TDFN Packages • This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant Figure 1.
