how to interface pic16f877a with eeprom

snishanth512 · Jan 9, 2013

I need to store 1024 x 8 bits of data.

Which eeprom is best suited for PIC16F877A?

please list some good eeproms.

You can use an external SPI or I2C device.
Depending on compiler, may have built-in API functions to perform this access.

Hi,

As for the type of chip, buy the largest you can find, they are just as cheap as the smaller ones.
Two types, I2C and SPI interfaces shown here, many others available.

What Andre means is that whatever complier you are using, Assembler, C, Basic , you will probably find that they have an SPI or I2C program code routine ready made in their libraries, though it is possible to code up your own.
