I'm about a to choose a chip to store a mp3 file (few mo) in it. But I don't really know how to well choose such a memory. Should I go for a flash memory? Eeprom? Nand? Nor?
What kind of parameters should I consider in my choice?
While consulting some distributor online shop, I figure out that SPI communication is widely use instead of I2C or UART. Is there a reason for that?
The memory will store only one file of few mo. The idea of the design is to load a part of the file in the MSP430 (the µC I'll use), process the data and then send it to a DAC. Since MP3 file have a sampling rate of 44100 Hz, I think the transfer speed has to be 4 or 5 time greater. I never use a memory or even audio conversion (from Digital or Analog) so I don't exactly know the require speed.
