AT93C46 Datasheet PDF

Thanhs agains so much!!! Just give me an idea about the protocol used. Other differences can be found in their datasheets which are readily availa. SPI with and 93C PIC93c46and others. But I am not clear how to evaluate the design.

93C46 – x8(1k) Serial CMOS EEPROM Technical Data

But instead of trying this circuit on board, first i want to simuate in PC. Only will send shifted data according to at933c46 and address.

Here you have some hints: If you can use eeproms with I2C or 3-wire interfaces then goto: PC Programming and Interfacing:: The software currently supports these devices: Some chips are on board. Seems your totally not familiar with datasheet reading ta93c46 2MHz is the maximum clock frequency for the 93c46 clock line mostly for 5V operation only.


This was revised looking at information in the AT 93c46 data sheet. Proteus-Microwire-req – have you seen it?

Thanks for your help!!! Because pic should not generate the clock while reading. Look it over and see if it makes sense according to data sheet information. Attached is a revised version of your original file eewr.

And i am planning to do that with Proteus. Where is my fault? Indicate the suffix letter whether 93C86A or 93C86B follow the datasheet if it is B version as regards s.

But Datahseet wrote code for it but not work yet. Try serial eeproms such as for example 93c46 and other members of that family.

Now I want to explain that I did. I had 93c46 ‘s datasheet and wrote a firmware. However, there is no library about 93c46 in Proteus. SPI with 89v51rd2 and 93C Do you use exact timing as described in the datasheet for writing to it?


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.

I extracted it from winpic But it didn’t work. I use c51 programmed a spi interface program visit cs,the program can visit 93c46 and xicro ,but cs don’t response, who can help me? I post full my code used 93c46 here could you fix it datasgeet me, please!?! Hi, i have an JDP programmer.

I have complated the firmware for that.
