And if so how would I go about doing this? Well the good news is its a late model and I have everything I need from a junkyard for very cheap. I would still like to know why it is able to write but not read?

This is what it looks like when using the clip: There must be a procedure 935c6 clone the new cluster from the old.

Jan 11, 3. I have also erprom 8dip versions of this eeprom in this same programmer and they never give errors so I must assume it is the clip. My best guess is a flaky connection on one of the wire to pin connections at the back end of the clip.

I just figured why not try with my arduino and eeprok a thing or two. Hi, What do the professionals do when they need to change instrument cluster? I am trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer. Ill see what I can do about separating that chip. Why is so8 test clip causing read errors with 93C56 eeprom TL programmer?

93C56 – x8(2k) Serial CMOS EEPROM Technical Data

No clue how do I go about getting this info? But what is the format of the data? Jan 10, 2. It may be cheaper and less risky to go to a Cherokee dealer and get him to do it You May Also Like: I just wonder if moving the chip might be a solution. I know this guy here did it with an off the shelf programmer, which is quite expensive compared to the arduino I all ready own.

Apr 30, 1, No, create an account now. I’ll see if I eprom find my old bitbasher – but given the datasheet you could figure it out. Your name or email address: Is this something eeprpm arduino can handle?

Why is so8 test clip causing read errors with 93C56 eeprom (TL866 programmer)?

Quote of the day. Just as the title states I wish to flash a 93c56 EEPROM in my jeep cherokee gauge cluster because my old gauge cluster has malfunctioned and the new one will have incorrect millage on the odometer. Do you already have an account? TomGeorge Design and Repair of industrial control systems. The test clip works fine when writing data also.

I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher. This is why we test Posted by nsaspook in forum: If I do go about pulling the code, is there a circuit eepro, needs setup and any pre written code for this?

Is there a connector next to this chip which does this? Everything runs on smoke, let the smoke out, it stops running Nov 5, 19 0. However eeprm I use the test clipit is giving me read errors on every other bit. But not that easy.

Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, Embedded Systems and Microcontrollers. Use this tutorial to get your FPGA development environment setup and understand the tool set and basic development process.

And here are a few other bit values, spliced together to save space In every case except FFFFthe even numbered bits 0,2,4, Jan 10, 1. Not to mention so many people in the jeep community have reprom and would benefit from this. It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: Given that it’s ‘in-circuit’- I presume soldered – you’ll probably need to break the eeptom to CS, SK ,DI DO, so as to prevent the existing seprom from preventing your operations.

Yes, my password is: Digital Signal Processing is the mathematical manipulation of an information signal, such as audio, temperature, voice, and video and modify or improve them in some manner.

If you had the appropriate sw from the manufacturer I bet you could do this via the OBDII connector – but I also bet they’re not telling you how!

Please do not take anything for granted, the answer maybe dead simple but I’m just not seeing it.

3-Wire Serial EEPROM

93C46/A, 93C56/A, 93C66/A

 Standard Voltage and Low Voltage Operation:

VCC = 2.5V to 5.5V

VCC = 1.8V to 5.5V

 FT93C46: 128 x 8 or 64 x 16

 FT93C66: 512 x 8 or 256 x 16

 Industry Standard 3-wire Serial Interface.

 Self-Timed ERASE/WRITE Cycles (5ms max including auto-erase).

 Sequential READ Function.

 High Reliability: Typical 1 Million Erase/Write Cycle Endurance.

 Industrial Temperature Range (-40o C to 85o C).

 Standard 8-pin PDIP/SOIC/TSSOP Pb-free Packages.

The FT93C46/56/66 series are 1024/2048/4096 bits of serial Electrical Erasable and Programmable

Read Only Memory, commonly known as EEPROM. They are organized as 64/128/256 words of 16 bits

each when the ORG pin is connected to VCC (or unconnected) and 128/256/512 words of 8 bits (1 byte)

each when the ORG pin is tied to ground. The devices are fabricated with proprietary advanced CMOS

process for low power and low voltage applications. These devices are available in standard 8-lead

PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP packages. Our extended VCC range (1.8V to 5.5V)

The FT93C46/56/66 is enabled through the Chip Select pin (CS), and accessed via a 3-wire serial

interface consisting of Data Input (DI), Data Output (DO), and Shift Clock (SCL). Upon receiving a READ

instruction at DI, the address is decoded and the data is clocked out serially on the data output pin DO.

The WRITE cycle is completely self-timed and no separate ERASE cycle is required before WRITE. The

WRITE cycle is only enabled when the part is in the ERASE/WRITE ENABLE state. Once a device

begins its self-timed program procedure, the data out pin (DO) can indicate the READY/BUSY status by

DS93CXX-A-page1

93C46/A, 93C56/A, 93C66/A

(A) READ

The Read (READ) instruction contains the Address code for the memory location to be read. After the

instruction and address are decoded, data from the selected memory location is available at the serial

output pin DO. Output data changes are synchronized with the rising edges of serial clock SK. It

should be noted that when a dummy bit (logic “0”) precedes the 8- or 16-bit data output string.

To assure data integrity, the part automatically goes into the Erase/Write Disable (EWDS) state when

power is first applied. An Erase/Write Enable (EWEN) instruction must be executed first before any

programming instructions can be carried out. Please note that once in the Erase/Write Enable state,

programming remains enabled until an Erase/Write Disable (EWDS) instruction is executed or VCC

To protect against accidental data disturb, the Erase/Write Disable (EWDS) instruction disables all

programming modes and should be executed after all programming operations. The operation of the

READ instruction is independent of both the EWEN and EWDS instructions and can be executed at

(D) ERASE

The Erase (ERASE) instruction programs all bits in the specified memory location to the logical “1”

state. The self-timed erase cycle starts once the ERASE instruction and address are decoded. The

DO pin outputs the READY/BUSY status of the part if CS is brought high after being kept low for a

minimum of 250 ns (tCS). A logic “1” at pin DO indicates that the selected memory location has been

erased, and the part is ready for another instruction.

The Write (WRITE) instruction contains the 8 or 16 bits of data to be written into the specified memory

location. The self-timed programming cycle, tWP, starts after the last bit of data is received at serial

data input pin DI. The DO pin outputs the READY/BUSY status of the part if CS is brought high after

being kept low for a minimum of 250 ns (tCS). A logic “0” at DO indicates that programming is still in

progress. A logic “1” indicates that the memory location at the specified address has been written with

the data pattern contained in the instruction and the part is ready for further instructions. A

READY/BUSY status cannot be obtained if the CS is brought high after the end of the self-timed

(F) ERASE ALL

The Erase All (ERAL) instruction programs every bit in the memory array to the logic “1” state and is

primarily used for testing purposes. The DO pin outputs the READY/BUSY status of the part if CS is

brought high after being kept low for a minimum of 250 ns (tCS). The ERAL instruction is valid only at

(G) WRITE ALL

The Write All (WRAL) instruction programs all memory locations with the data patterns specified in the

instruction. The DO pin outputs the READY/BUSY status of the part if CS is brought high after being

kept low for a minimum of 250 ns (tCS). The WRAL instruction is valid only at VCC = 5.0V ± 10%.
