What is an EEPROM?

An EEPROM, or electrically erasable programmable read only memory, like a regular ROM chip, uses a grid and electrical impulses in order to create binary data. However, the difference between ROM chips and EEPROM chips is that EEPROM chips can be reprogrammed without removing them from the computer, contrary to basic ROM chips which can only be programmed one time. A localized charge from an electrical field is all that is needed in order to erase the EEPROM chip. Also, the entire EEPROM chip does not need to be erased at one time, which therefore allows specific changes to be made. Other erasable programmable ROM (EPROM) chips must be entirely erased if any data is to be erased. EEPROMs are constructed as arrays of floating-gate transistors.

Types of EEPROMs

There are several different kinds of EEPROM chips at Future Electronics. We stock many of the most common types categorized by several parameters including memory density, memory organization, nominal supply voltage, maximum clock frequency, maximum write cycle time, maximum access time and packaging type. Our parametric filters will allow you to refine your search results according to the required specifications.

EEPROMs from Future Electronics

Future Electronics has a wide range of programmable EEPROMs from several chip manufacturers that can be used for a flash EEPROM, serial EEPROM, EEPROM burner, serial (I2C EEPROM, spi EEPROM,…), parallel EEPROM, microchip EEPROM or any other electrically erasable programmable read only memory (ROM) chips suitable for programming. Once you decide if you need an I2C Interface Protocol, Micro-Wire Interface Protocol, Parallel or SPI Interface Protocol EEPROM, you will be able to choose from their technical attributes and your search results will be narrowed to match your specific EEPROM application needs.

We deal with several manufacturers such as Microchip (Atmel), NXP, ON Semiconductor, ROHM Semiconductor or STMicroelectronics, among others. You can easily refine your EEPROM product search results by clicking your preferred EEPROM brand from the list of manufacturers below.

Applications for EEPROMs:

EEPROM memory is used in computers as well as other electronic devices in order to store small amounts of data which must be saved when the power is removed such as in calibration tables or device configuration. If larger amounts of static data need to be stored, like in USB flash drives, a flash EEPROM is more economical to use than a traditional EEPROM device. EEPROM memory can also be found in various other products which are not strictly memory products, including digital potentiometers, digital clocks and digital temperature sensors. These devices can have a small amount of EEPROM in order to store calibration information or other data which needs to be available in case there is a loss of power.

Choosing the Right EEPROM:

With the FutureElectronics.com parametric search, when looking for the right EEPROMs, you can filter the results by category. We carry the following categories of EEPROMs:

  • I2C Interface Protocol EEPROM
  • Micro-Wire Interface Protocol EEPROM
  • Parallel EEPROM
  • SPI Interface Protocol EEPROM

Once you choose the EEPROM category, you can narrow them down by various attributes: by memory organization, nominal supply voltage, memory density, maximum write cycle time and maximum clock frequency to name a few. You will be able to find the right chip for a serial EEPROM, flash EEPROM, microchip EEPROM, EEPROM burner, parallel EEPROM, serial (I2C EEPROM, spi EEPROM,…) or any other electrically erasable programmable read only memory chips for programming.

EEPROMs in Production Ready Packaging or R&D Quantities

If the quantity of EEPROMs you require is less than a full reel, we offer to our customers several of our programmable EEPROMs in tray, tube or individual quantities that will help you avoid unneeded surplus.

Future Electronics also offers its clients a unique bonded inventory program designed to eliminate potential problems that may arise from an unpredictable supply of products that could contain raw metals and products with erratic or long lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
