24LC41A  
1K/4K 2.5V Dual Mode, Dual Port I2C™ Serial EEPROM  
The 4K-bit microcontroller port is completely indepen-  
dent of the DDC port, therefore, it can be accessed  
continuously by a microcontroller without interrupting  
DDC transmission activity. The 24LC41A is available in  
a standard 8-pin PDIP package in both commercial and  
industrial temperature ranges.  
Features  
• Single supply with operation down to 2.5V  
• Completely implements DDC1/DDC2interface  
for monitor identification, including recovery to  
DDC1  
• Improved noise immunity  
Package Type  
• Separate high speed 2-wire bus for  
microcontroller access to 4K-bit Serial EEPROM

Description  
4K-Bit  
Serial  
EEPROM  
The Microchip Technology Inc. 24LC41A is a dual port  
128 x 8 and 512 x 8-bit Electrically Erasable PROM  
(EEPROM). This device is designed for use in applica-  
tions requiring storage and serial transmission of  
configuration and control information. Three modes of  
operation have been implemented:  
MSCL  
• Transmit-only mode for the DDC Monitor Port  
• Bidirectional mode for the DDC Monitor Port  
Pin Function Table  
• Bidirectional, industry-standard 2-wire bus for the  
4K Microcontroller Access Port  
Name  
Function  
DSCL  
Serial Clock for DDC Bidirectional mode  
(DDC2)  
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 pin. A valid high-to-low transition on the  
DSCL pin will cause the device to enter the transition  
mode, an look for a valid control byte on the I2C bus. If  
it detects a valid control byte from the master, it will  
switch to Bidirectional mode, with byte selectable read/  
write capability of the memory array using DSCL. If no  
control byte is received, the device will revert to the  
Transmit-only mode after it received 128 consecutive  
VCLK Package Type pulses while the DSCL pin is idle.
