What is needed for a 512Kb HDMI EDID EEPROM? (re: 512KB IC2 EEPROM) [closed]
I'm trying to build an HDMI "dummy" plug that simulates a plugged-in monitor (to trick GPUs into thinking a monitor is plugged in).
Many of these "dummy" adapters exist and are ...

What is a color bars vector diagram?
I'm reading the datasheet of the "AT7456E". This component is an OSD (so-called "on screen display") used on the flight controller of my drone project.
In the datasheet there was ...

Non-standard bitrate for I2C EEPROM
I have an I2C bus containing only 2 devices: a microcontroller and a Microchip 24LCXXX EEPROM.
In the datasheet of the EEPROM only maximum speed is specified (which is 100 kHz @VDD<2.5 V and 400 ...

Can I write and read a parallel EEPROM content with Analog Discovery 2?
I am wondering if I can read or write the contents of a parallel EEPROM (e.g., 28C64) using Analog Discovery 2. Is C/C++ necessary for this purpose, or is Java sufficient (since AD2 allows scripting ...

Is it safe to replace a 120ns Flash memory with a 90ns part?
Here is an old PLC board with a pair of AM29F200AB-120SI SOP-44 256kB 5V flash chips. One is unable to retain data, after nearly three decades in service.
These are very challenging to find today, ...

Does "field electron emission" used in EEPROM work better than "hot-carrier injection" in NOR Flash?
After deeping research based on my another question, I continued comparing Flash and EEPROM based on wikipedia comparison table.
From wikipedia about the Flash memory:
Programming

Differences between EPROM and EEPROM
I found one valuable Utmel blog which explains the three things:
The internal chip can be erased by irradiating ultraviolet rays through the hole. The EPROM eraser is needed to complete the chip ...

Is it possible to simulate an EEPROM with the STM32 F446RE chip?
I looked through the STM32 F446RE datasheet and was unable to find a way for the chip to keep persistent data values for when it is turned on and off, or when reset.
The only alternative I can think ...

Converting an application from ESP32 board to STM32 board
I wrote an app for my ESP32 but then I learned that ESP32 doesn't work well on batteries, since they got drained pretty quickly.
So I bought a STM-32 board (NUCLEO-32, STM32L432KC MCU): https://www....

Issues reading data back from 24LC512 EEPROM via interrupt on MSP430F47187
I have interfaced MSP430F47187 with 24LC512 EEPROM. I am able to write to the EEPROM without any issue but reading the data from the EEPROM is problematic as the reading stops after a while.
I have ...
