CAT24C21

1 kb Dual Mode Serial

EEPROM for VESAt

“Plug-and-Play”

Description

http://onsemi.com

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

I C 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.
