Serial EEPROM for Low Power
with software write protect
Data Sheet
OVERVIEW
The KS24A010/020/040 serial EEPROM has a 1,024/2,048/4,096-bit (128/256/512-byte) capacity, supporting the
standard I
2
C™-bus serial interface. It is fabricated using Samsung’s most advanced CMOS technology. It has
been developed for low power and low voltage applications (1.8 V to 5.5 V). Important features are a hardware-
based write protection circuit for the entire memory area and software-based write protection logic for the lower
128 bytes. Hardware-based write protection is controlled by the state of the write-protect (WP) pin. The software-
based method is one-time programmable and permanent. Using one-page write mode, you can load up to 16
bytes of data into the EEPROM in a single write operation. Another significant feature of the KS24A010/020/040
is its support for fast mode and standard mode.

How to configure HDMI, LVDS, and VGA to output simultaneously and output different contents in sate4412?
As the title says. I found a detailed configuration file about the Allwinner A10 development board on the Internet. I wonder if there is a similar method for Sate4412. Thank you....
