Hi all,
Has anyone used Microwire serial EEPROM with MSP430?? Does
normal SPI works or you have to go Bit banging? Thanks in
advance.... Start a New Thread

I'm not sure if the built-in SPI is compatible with driving a 93C46
EEPROM because of the busy/ready period after writing or erasing. At
first glance it seems to be incompatible if you want to achieve maximum
write speed. However, you can probably do some worst-case-after-write
delay and then verify as a matter of protocol to permit the use of the
SPI peripheral.

I had to make that same decision and I chose to bit-bang it. The data
rate was tolerable for me and it was so easy to code. I never
regretted using bit-banging.

I'm sorry I can't give a direct answer to your question but my answer
is based on personal experience.
