Frequently Asked Questions

1.Can the memory 24C16 be replaced by 24C08?
Yes, large-capacity memory blocks can be substituted for small-capacity memory blocks. Taking 24C16 as the dividing line, the first section: 24C16, 24C08, 24C04, 24C02 capacity decreases in turn, within this range, large capacity can replace small capacity; second section: 24C64, 24C32, 24C128 capacity increases, in turn, Large capacity can replace small capacity.
2.What is the difference between the program stored in the 24C08 memory and the program stored in the MCU?
24C08 is an I2C serial memory, which can only be used to store data but cannot store programs. It has only two lines to read and write. The internal program memory of the MCU is parallel, and the program instructions are read through the address bus, data bus and control bus.
3.Is the 24C08 the same as the 24LC08?
The capacity of 24LC08 is larger than that of 24C08 and smaller than that of 24C16.
