As we deal with rather limited micro-controllers, we will skip the families of EEPROM chips which data are addressed in parallel mode. In this mode, 8 bits arranged memories require 8 pins from the micro-controller which is too much pins consuming even though the gain in speed is noticeable.

Instead, we will look after chips which data is addressed in serial mode. Mainly two types of serial communication protocols are available: Both have there advantages and draw backs. My preference goes to SPI in spite of the highest number of pin required. In absolute, SPI is faster and I use this protocol a lot in my 25lc32.

Coming next after the 25LC chips are the 25AA chips. They differ from their supply voltages:.

Within the 25LC family, some references are getting obsolete and Microchip suggests to use the A versions instead. In most cases, the A version e. Care shall be taken at the B versions which have a different meaning!

B versions have something to do with the way data are arranged internally.

In other words, you may read carefully the chip data sheets before trying to tweak the proposed code. Datasheet chip has its own properties in terms of: Next is a short recap of the chip properties.

Data Sheets

Write and read functions are available with and without address setting. When the address argument is not set, the write or read functions are executed at the actual memory location.
