spi minium clock frequency ...

Former Member over 11 years ago

how to find spi minimum clock frequency? ...

eg : 25LC512 SPI based eeprom ic .

maximum clock frequency is defined in this data sheet 20MHZ but minimum clock frequency is not specified ,

There is no minimum - SPI is clocked and one of the nice things is that you can usually stop part way through a transfer and then start up again many clock cycles later with no errors.

That is useful to know, I'm planning a project using SPI and it will be very handy to do things in a modular fashion and get things working at a low frequency before taking it up to full speed.
