hI GUYS ,
I have a pic running at 5v , have SPI BUS with level converters to 3.3v , but now looking at adding a flash chip to the spi bus
and i prefer not to ad more level converters for the ce/hold/wp inputs if i can avoid
wondering if anyone has a solution for using a FLASH chip running at 3.3v , where the inputs for CE , hold , WP are 5v input tolerant
most Flash chips i have found have internal pullups on these pins as well
i prefer to do a flash for the size/ speed relative to eeprom , but most eeprom can run at 5v
regards
sheldon
