eeprom

We are working on a board and we need to read one eeprom with part number ds2432. It is 1 wire and connected in series with MCU. I have done making MCU development and evaluation kit. Not sure how to read ds2432. Please help me which programmer I can use. Or which evaluation board or circuit I...

Hi, I noticed that 4.7k ohm pull-up resistors are used in this circuit on the read/write memory pins: Saundby's MAG 85(scroll down to yellow text), but in other circuits where the read/write / io/m signals are decoded by the 74138 for example, pull-ups are not used? Is it because in the MAG 85...

Hi, I think that this looks correct, please confirm. I am ONLY showing my connection to the 62256 32k x 8 ram CE pin that I added to the web page picture, slide 15: When A13,A14,A15 are all low, the 2764 should be selected. When A15 is high, the 62256 should be selected. Keiichicom

I watched Ben eater's video it's about building computer based on 6502 microprocessor and I'm stuck at part3 ( Assembly language VS Machine code). He was programing 32k at28c256 EEPROM and he programmed by assembly to blink LED. Here his code: And he uploaded code to EEPROM by Minipro TL866...

Hi community, I'm Marco from Italy, I'm an electronic developer and I like automation in general. I would like to share my problem with community, to know what do you think about this. I'm developing an electronic board for general automation purposes, on this board there is a STM32F104 that...

Hello, it's my first time playing around with external eeproms (ik this chip has internal eeprom but I want to experiment with external eeproms) I have a test setup where my chip connected to an LED and a button. so when I click the button a value (ex.: 5) should be written on my eeprom and...

Hey, first of all I would like to say that basically all of what I'm talking about is far far away from my comfort zone and everything I know is from a 30 minute research on this topic. So I am trying to reset BIOS password on an old ASUS X51L laptop because everytime I turn it on I first have...

Hey guys I am trying to find the checksum for a hex string. Below attached is the hex code that have checksum already found out and in the 2nd bottom I need to find the checksum 08 D0 1B 60 08 D0 1B 60 00 00 00 00 00 00 00 00 00 0B 75 4B 00 00 91 DC So, in the upper hex code the last 4...

I'm using ATmega1280 with an external clock and I have some questions about the "safe operating area" for preventing EEPROM corruption with BOD. The external clock is: Crystals 14.7456MHz 18pF HC49S SMD by CITIZEN, without clock division. LINK to ATmega1280 datasheet In the datasheet of...

I have started using total phase I2C host adapter. when I am trying to communicate with my target i could not able to communicate !! it is a simple process of connecting two wires of host adapter to my target but it is not working out. if some one has worked with any of these two parts( Total...

My old PC motherboard's bios chips were corrupted and it's an old 1155 socket so there were no available replacements. I believe I have the necessary tools to attempt to erase and reprogram the chip, but I'm not sure what I need to do. There isn't much STM32 resources online to guide me...
