The main difference between these two eeproms is in the way they are interfaced with something else .. The 93C46 has 3-wire serial interface (Din, Dout and Clock) whereas the 24c04 uses 2-pin I2C interface and can be easily connected to any host I2C device (or bus) .. Other differences can be found in their datasheets which are readily availa
for 24c01 to 24c16 (including 24c04) you have only 1 byte for addressing... (works fine with 24c01 and 24c02) for extra addressing you must use the 3 lower bits of I2c-address so you must chage your writing/readings routines... {the extra stuff over 0xA0 to the 3bit extra addressing... } unsigned char ReadBYTE(unsigned int Addr) {
I am trying to make a i2c connection between 24c04 eeprom and pic16f877. I wrote the codes that need for. But I guess, it has some problem. But i can't find it. #define LC01CTRLIN H'A0' ; I2C value for CONTROL BYTE when ; INputing data to the eeprom #define LC01CTRLOUT H'A1' ; I2C value for CONTROL BYTE when ; requesting OUTput from t

Hello Everybody .. I am working on a project in which I have to interface an IR based digital thermometer with PIC16F877A .. My task is to fetch the thermometer readings i.e. Temperature .. There is an eeprom IC inside the thermometer (connected over I2C bus), may be 24c04, which saves the readings and thermometer can store 30 readings .. My quest
I am using 24C64 with Atmega32, the concept is borrowed from that of Data-logger from dharmanitech.com. To increase memory I wish to use 24C256 and for some trials I tried to use 24c04. The routines for eeprom are taken from the files from the above link i.e. 24C64.h and 24C64.c. Now the question is th
hello, i'm beginner in this, so plz heeelllllllpppp me .... for "programming to 24c04 with 89c52 in read mode specially; i wants write many values of integer n read continuously ....i m totally confused how to use eeprom in my programming .....i hav attached my prog sample.....plz help me ....this is my last hope....:sad::sad::sad::sad::sad::sad::
HOW ARE YOU? YOU NEED C/C++ SOURCE FOR 24c04? 93C46? GO TO . YOUR KNOW THINK. HELP.
Very nice project but its pity that this programmer dont support from 24C32 and up, such 24C128,256,512 - - - Updated - - - Maybe will be exellent to leave users to set over firmware source what 24C.. they whant on what taster, with added support for over 24C32 and up, like : T1 24C02 T2 24c04 T3 24C128 T4 24C256 T5 24C51
Hi all, I know there are some pretty big difference between these eeprom memory. But I forget what it is. The difference could be in the acknowledge bit or the write protection pin. I just can't find the difference. All I remember was that I have to change my design last time when one of the particular mfg. have too long a lead time. Anyone
hi friends, can some one guide me how to write the serial data comming from pc. to the eeprom like 24c04..? i m using 89c51 MCU from ATMEL and using KAIL UV-2 to program it in "c" i can take the serial data out on the ports.. but i am stuck at how to write it to the eeprom like 24c04 and read it back.. on serial port..( (...)

Use Atmel/philips 24c04 I2C based eeprom and interface it with your micro by writing a siple routine to make two pins of your micro work as I2C
Hi: I have made a USB serial eeprom programmer recently. I wanna find a partner to sell this production. below is the feather of this production. 1. 8 bit MCU, support self-updata firmware. - easy to updata for future serial eeprom (Support IAP) 2. USB port interface - easy to connect and support PnP 3
I use the DSPIC 30F4011 for my project. When I config to protect code. The eeprom alway readed is 0x00. My PCb have designed without the external eeprom such as 24c04 ... Please help me ! Thanks a lot !
It's possible via the parallel port .. Here is an example with bigger eeprom, but the same principle applies to the 24c04: Also, see: MemPlus 1.2 works with a lot of eeproms .. IanP :| /* * 24C32_1.C * * Illustrates how to write to
24c64 has a different frame format compared to other eeproms .. 24c04 and 24c64 frame format differs.. please check the datasheet for more details.........
24c04 is 4kB eeprom according to datasheet. 4kB = 4096 = 15bits of addresses right? so the address would be 0x000 to 0x2FFF ?? The datasheet says organized with 32 pages of 16 bytes each, the 4K require a 9bit data word address for random word addressing This is a [B
Dear Sirs, Please help me by guiding me to correct the Code i have written. I am using Hyper Terminal for inputting 8 Bytes of data to 8051, which has to be written in to eeprom 24c04 at ADDR 0A0H From RAM location 30H to 37H. After writing cycle is completed, I want to read from eeprom and again save in RAM starting location from (...)
I know, due to the difference in address width we can't use code for 24C02 while using 24C1024. But I have used 24c04 instead of 24C02 & it is working alright. So my question is that whether code will change for every eeprom or it is applicable for group. I will explain my doubt further. Code A will work for 24C02/04/08, code B will work for 24C
It uses I2C/TWI. So, you can use the I2C library of mikroC. Here's the related link with an example of 24C02. Read the datasheet of the 24c04 and you can program the eeprom as required. You can find an example here:
Hi everybody, does anyone have some experience with the serial eeprom from Catalyst, especially the CAT93C86 with Program Enable Pin. Are there some public errors like loss of information or reading problems during PE at GND? Please let me participate on all your knowledge and experiance. THX Curgi ********************************
Hi, I make a simulation of a avr at90s8515, the programm .hex is ok, this run fine... but ICCAVR create me a file X.eep that i cannot load from proteus...When the simulation run, data aren't the eeprom data( but FF). I d'ont understand because there is no error message when compiling the simulation whith my file X.eep... Somebody can help me ?

I am having some question related to embedding flash and/or eeprom in my MCU ASIC design. (1) Isn't it true that flash requires a different process technology than CMOS? If that's the case, how can I put flash and the control logic into a single die? (2) Is it true that I can get some kind of flash IP from some companies, or even the foundry the
