EEPROM or E2PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.
In this application note, EEPROM programming is explained for TI’s 10 to 12.5-Gbps retimers. To program an EEPROM efficiently and accurately, system designers must decide when to use programming features for retimers such as Common Channel Configuration, Address Map Headers, and CRC Bytes.
This Memory Map shows you what each memory location is used for. The valid parameter range is also shown in the memory map. Keep in mind; you cannot store device parameters unless you are in ‘configuration’ mode. You may read device parameters in ‘run’ of configuration mode.
Serial EEPROM devices like the Microchip 24-series EEPROM allow you to add more memory to any device that can speak I²C. Today we're going to learn how to read and write serial EEPROM devices using Arduino.
17 Αυγ 2023 · by Khaled Magdy. In this tutorial, you’ll learn what are EEPROM memories? How do they work? What are their applications? And how to interface the internal EEPROM memory within our PIC Microcontroller chip. We’ll also develop the required firmware drivers for EEPROM memory to perform Write/Read operations at any memory locations we want.
EEPROM is non-volatile memory used in electronic devices to store data that must be saved when power is removed. This non-volatile memory is particularly important when an application requires different start-up configurations than the factory default settings. Upon device power-up, data saved in the EEPROM will load automatically to the device.
The main read only memory devices are listed below: ROM (Mask Programmable ROM—also called “MROMs”) EPROM (UV Erasable Programmable ROM) OTP (One Time Programmable EPROM) EEPROM (Electrically Erasable and Programmable ROM) Flash Memory - This device is covered in Section 10. HOW THE DEVICE WORKS.
