Very rare the eeprom IC itself have problem usually only the program run and you just have to reprogram it. In LiKOM Monitor, whenever the eeprom have problem, the front panel all the LED’s will run from left to right and right to left. It’s a common fault and reprogramming solved the problem. Remember, eeprom data loss could happen to any kind of electronic equipment that uses the eeprom IC.
The world’s most reliable EEPROM supplier, offers a full range of serial EEPROM devices in numerous packages. EEPROM itself is a robust memory technology and is well-developed. It offers non-volatile storage like Flash memory, but for smaller storage volumes. It can be written and erased many times more than Flash, and has a more granular memory architecture.

It can never be modified again after this operation. All protected memory locations will forever be unwritable, but the locations not protected will remain subject to WEN and WDS.
PRWRITE Write a value into the protection register. All memory locations before and including the value in R0 will become write protected. As with READ and WRITE, the address in RO refers to a 16 bit memory location, valid range is 0 to 63. Unprotected memory locations are still subject to WEN and WDS, but protected locations are unwritable unless the protection register is changed or cleared. PRDS Permenantly freeze the protection register to its current value.
Has lots of data sheets on-line. I used their to write the code. Their literature number is 800-272-9959.

Early versions of this code worked with the 93C56 and 93C57, which have more memory. Unfortunately, these chips use an 8 bit address field, whereas the 93C46 uses only 6. The code can be adapted to work with these larger chips. The early versions are long since gone.
With PonyProg and SI-Prog you can program Wafercard for SAT, eeprom within GSM, TV or CAR-RADIO. Furthermore it can be used as a low cost starter kit for PIC and AVR. Support PonyProg PonyProg works also with other simple hardware interfaces like (STK200/300),, and DT-006 AVR (by Dontronics).
The fact that you have frozen the protection register is stored in the non-volatile memory (10 year min retention). There is no way to undo this operation. All future PRCLEAR and PRWRITE operations will have no effect. The menu-driven example code includes a copy of these routines and calls them properly to allow the user to view and edit the values within a 93CS46. It is not necessary to erase memory locations before writing.
As mentioned above, four wires are actually required, and the 93CS46 has two additional lines that work together with a special write protection register. This code should work 'out of the box' with a 93CS46 chip.

For that purpose it uses a 10 pin IDC header. A cable to connect from the programmer to a 10pin IDC header is included.
The 2-wire interface, called I 2C or IIC or 'I squared C' uses only two wires, regardless of how many chips are attached. I 2C is a trademard of. The three wire interfaces include SPI and Microwire, which is a trademark of. As the pressure on engineers to make products smaller has grown, semiconductor manufacturers have introduced several new interfaces, usually aimed at lower a product's size and cost. And undoubtedly many more will appear in the future. As a practical matter, the code offered below only works with the Microwire 3 Wire interface, and is specifically intended to work with the 93C46, which is a standard part available from a variety of distributors.
They only require a 5 volt power supply (some 3V only versions exist too). Because these chips use a serial interface, they can not be read quickly enough to serve as conventional memory. In addition, a considerable length of time (milliseconds) is required to perform a write operation. They typically hold less than 1024 bytes of memory. However, they usually cost less than $1.00 (US) for single piece quantities, making them pretty desirable memory devices for storing configuration parameters or other bits of information that should be retained when the power is lost. There are several types of Serial EEPROMs, but most of them fall into either a 2-wire or 3-wire interface category. Usually, the 3-wire devices require an addition wire (beyond the 3 for data transfer) for each chip to be used.
Or at least is was some time ago when I put their sticker on my phone. Now has data sheets on-line for most of their products. They offer the 93C46, as well as a variety of other EEPROMs.
The erase functions provided in the 93C46 are unnecessary (for the chips I've used, double check your data sheet). The erase functions are not implemented here. These 93C46 Serial EEPROM devices are used in many commercial products where the data contained within the chip, though only 128 bytes, is considered confidential and proprietary. This code library may not be used to 'break into' the data stored within devices in commerical products. Use of this code library to modify the behavior of commercial products, without the expressed written authorization of the manufacturer, is also prohibited.

It applies to both the 93C46 and 93CS46 chips. It is advisable to disable writing if no additional write operations are expected soon. In this state, the chip may have better resistance to accidental data loss due to problems on the power supply, noise on signal lines, etc. Routines specific to the 93CS46 chip PREN Enable the protection register.

IMPORTANT: Perform the exercises in this tutorial before you begin working with any modules. USING THE ASERSM1A SERIAL EEPROM IN-CIRCUIT INTERFACE ADAPTER This document describes how to use the ASERSM1A adapter, including how the plug is attached and the purpose of the voltage selection slide switchs. IMPORTANT: Read this document and become familiar with the purpose of the slide switchs as it will allow you to work suc- cessfully with most parts in-circuit and confirm a “GOOD READ” of eeprom data. Also note the position of the black cable plug when installed on the adapter: The BROWN wire is always on the right, below the arrow.

They use a serial bus interface, which allows them to be packaged in inexpensive 8 pin packages. To you, the 8051 system designer, these little chips offer a nifty way to store a small amount of data in non-volatile memory, using only a few of the port pins, and without raising the system's cost much. They are usually specified to retain the data for 10 years and to endure 100,000 write operations before failure.

SERIAL EEPROM TUTORIAL - 93C56 (AUTOMOTIVE VERSION) This tutorial (directed at automotive applications) describes how to use the system by providing a series of hands-on exercises using an actual 93C56 serial eeprom. Although this tutorial covers more than just locksmith applications, it will teach you to use the additional capabilities of your KLS-1 package.
For the 93CS46, if this location is 'protected', no data will be written, regardless of calls to WEN and WDS. Writing takes a considerable length of time (milliseconds). This routine just waits for it to finish before returning. Hope you don't have any polled I/O you wanted to keep doing! WDS Disable writing. This disables write operations.
The code below works with the 93CS46 Serial EEPROM. It can be used without much difficulty with a 93C46, by avoiding calls to the routines that manipulate the extended features of the 93CS46. Manufacturers has data sheets on-line for most of their EEPROM and microcontroller products. They have also added example 8051 code similar to the code below, as well as for I 2C parts they offer.

Compability with other 3-Wire serial EEPROMs The 93C46 chip should be usable, but care should be taken not to make calls to the functions which access the protection register within the 93CS46. The two extra pins not required for the 93C46 are manipulated by all the routines. To reclaim these pins, remove all the instructions that use ' pe' and ' pre' symbols. A simpler approach may be to set the bit addresses of these bits in the.equ statements to a bit within the 16 byte bit-addressable space, or perhaps one of the general purpose flag bits in the PSW, if you're not using it. It's up to you. I might make another version of the code specifically for the plain 93C46, if anyone wants it enough to. Please explain the difficulty you have using the code with a 93C46 (or the trouble you think you may have).
How to reprogramming 93c56 eeprom ic is not difficult. What you need is a eeprom programmer and the master copy of the software. If you knew that this particular model of equipment the eeprom always have problem then you should keep the original copy. That’s mean if the particular equipment came in with no power symptom and you have solved the problem you then can remove the eeprom and save the copy of the software in the harddisk through eeprom programmer. Whenever you want to reprogram an IC, you just need the original copy of the software to overwrite the faulty eeprom IC and it will work as new.
Valid address range for R0 is 0 to 63. WEN Enable writing. This operation must be performed before a write may be issued. This applies to both the 93C46 and 93CS46. Unlike PREN below, writing should remain enabled until a WDS is called. WRITE Writes the sixteen bit data in R2 (LSB) and R3 (MSB) to the location pointed to by R0. Writing must have been enabled using WEN.
Offers 2-Wire interface and SPI interface serial EEPROMs, but apparantly nothing which will work with the code below. Xicor once had a considerable collection of example code on-line, but they appear to have removed it. Distributors Within the United States, the easiest way to get ahold of a 93C46 is to call 800-344-4539 (MicroChip, maybe National) or 800-346-6873 (SGS Thompson). Both have a minimum order, appox $25, and these serial EEPROMs are only about $1 each. There are lots of other distributors too, but Mouser and DigiKey are probably the easiest, since they give out a free catalog This code was written to support the 93CS46. This 3-Wire interface chip actually has 6 wires.
The next access should be to this register instead of the memory. This call is required immediately before each PRCLEAR, PRWRITE, or PRDS. In addition, WEN may have to have been called, check your data sheet (or just do it to be on the safe side). PREN should only enable use of the protection register for the next access, so it should be called before every protection register access.
