Hi,

I am trying to design a circuit that will be able to erase the memory of an AT45DB321E eeprom device without removing it from the PCB. The only problem I am having difficulty with is how do I generate a clock pulse for the devices SCK pin?

I've never done this before so any help will be most appreciated.

Regards

Tony

This device uses a (compatible) SPI interface, if you use the SPI interface of your controller (and the SPI component) the clock will be generated for you.

Thanks for that, I've been looking around for a sample flowcode program for guidance but as of yet cant find one.

How do I enter "C7H" as an expression?

Check this blog post for example code.

For hex values use 0xnn, not nnH
