AVR-Chat

Good day to everyone.

I am going to make a signal pattern generator. initilly, i am using a serial eeprom to store data, an AVR controller and an SRAM. Upon power up the AVR read data from serial eeprom and pass to the SRAM. Then run a frequency counter on SRAM address to create a signal pattern.

If i remove the serial eeprom and AVR, change the SRAM with parallel EEPROM, will there any problem in read cycle? Datasheet for AT28C040 says endurance is 10 000 cycles. This means 10 000 read and write? so if i write once and read 1 million times is OK? Just need some inputs from experienced guys.

regards,
mago

Serial or parallel makes not difference, the wearout is only on writes.
You can read pretty much forever.

Yes.
