Reading and Writing Serial EEPROMs

The Prototyping Board Setup. Which was the previous technology in this area. A typical EPROM has a window on the top side of the IC to allow the ultraviolet rays to reach the memory cells in order to erase the memory.

The EPROMs had to be exposed to ultraviolet light for a convenient time period in order to get fully-erased. On the contrary, the RAM memory is volatile. Which means it does lose all of its contents when the power goes OFF. And this is going to be our task in this tutorial. To develop the required firmware to drive this memory module.

With all of these features in mind. Well, there are many situations indeed. And there are countless situations in which we use this kind of memory devices. These devices are actually embedded in almost all electronic devices you might ever know. MCU which controls your device behind the scenes. Enough of theory! The writing function should be taking a Byte-Wide value to write and an address of a memory location to write at.

Which can be easily done by defining the following. Then we head over to the main loop routine. Add the hex file and run the simulator. Here is the schematic for this lab. The same data is still resident in the same memory locations even after a hardware reset. Prototyping this project should also be an easy task. The tough part has been already done before writing the code.

Quote of the day.You do not need to erase the chip, one time. Nowadays due to advancement in technology several different kinds of EEPROM chips have been produced by creative minds working all over the world.

The parameters on which the majority of chip types have their basis on are things like maximum cycle time, memory organization, maximum clock frequency and type of packaging. The programming of EEPROM is very simple and according to many it is one of the easiest chips to understand and learn about.

The names of these pins are. The programming procedure of EEPROM is not that difficult however the process involves several technical details as well. If you are interested and want to know more about EEPROM then it is recommended that you should click this one by radio-electronics.

However, the code shown above for this lab will work flawlessly for almost any small project. You can use it to store data variables that work as configurations for your system e.Nowadays it is very common to see eeprom ic in electronic equipment. What is eeprom? As the name suggest, an EEPROM can be both erased and programmed with electrical pulses from a programmer kit, burner or the equipment itself.

Since it can be both electrically written into and electrically erased, the EEPROM ic can be quickly programmed and erased in circuit for reprogramming without taking them out from the main board. New EEPROM ic have no data blank inside and normally have to program it first with a programmer tools before it can be use on electronic circuit.

If you just installed a new or blank eeprom ic into a main board, even though with the same part number, I can say that the equipment will surely not going to work because the cpu or microprocessor do not know how to function.

Information or data stored in this type of memory can be retained for many years even without a continuous dc power supply to the ic. The current settings of the monitor will not be erased even when the monitor is switched off. When the monitor is switch on again, the stored settings in eeprom ic are used to set up the monitor for operation.

EEPROM ic seldom failed or damaged, they just lose or have their memories information corrupted may be due to high voltage and static discharge from a monitor. There are certain types of monitor designed where the eeprom ic is located under the belly of the picture tube. Prolong switch on and off will sometime caused the eeprom data to corrupt.

If the data files already corrupted, once reprogrammed the ic, they will work as good as new. You must save first the original data into hard disk and retrieve it when testing or reprogram the ic. For some Monitor brands where the eeprom ic data always corrupt, I have to save the good working Monitor data first for future use. EEprom Programmers comes in all designed, shapes and sizes. You can copy these devices data for troubleshoot replacement only.

You are not allowed to copy them for resale without a letter of approved from the supplier who manufactured them. The pony prog serial interface programming software is included and update version can be download from their website. If you want to know more information about the eeprom ic datasheet and cross reference for testing purposes, you can always log on to internet and search for it.
