The Microchip Technology Inc. 24LC41 is a dual-port 128 x 8 and 512 x 8-bit Electrically Erasable PROM (EEPROM). 24LC41 is designed for use in applications requiring storage and serial transmission of configuration and control information. Three modes of operation have been implemented:
• Transmit-Only Mode for the DDC Monitor Port
• Bi-directional Mode for the DDC Monitor Port
• Bi-directional, industry-standard 2-wire bus for the 4K Microcontroller Access Port

Upon power-up, the DDC Monitor Port will be in the Transmit-Only Mode, repeatedly sending a serial bit stream of the entire memory array contents, clocked by the VCLK/DWP pin. A valid high to low transition on the DSCL pin will cause 24LC41 to enter the bi-directional Mode, with byte-selectable read/write capability of the memory array. The 4K-bit microcontroller port is completely independent of the DDC port, therefore, it can be accessed continuously by a microcontroller without interrupting DDC transmission activity. The 24LC41 is available in a standard 8-pin PDIP package in both commercial and industrial temperature ranges.
