IAP Blocking for 400ms?

2006-05-10 by Bryce Schober

I just want to make sure that I'm reading this right before committing to
using a serial flash. It seems that the lpc21xx on-chip can't really be used
for eeprom emulation in real-time scenarios, since its sector erase takes
hundreds of milliseconds and is a blocking function. I guess that's why some
of philips' competitors have a separate data flash for such usage. The price
point of the lpc21xx doesn't look so good for us, when you have to tack on
an extra $1+ for an external SPI flash device.
