Description
Description
The Microchip Technology Inc. 24CS Family of Serial EEPROMs is the first Serial EEPROM to introduce support for 3.4MHz High-Speed Mode I2C Bus communication. Previous generation Serial EEPROMs have been limited to 1 MHz I2C Bus communication. This new feature narrows the speed performance gap between I2C bus communication and the much faster SPI bus communication while retaining the ease of use benefits of I2C.
