Suggested EEPROM for booting from serial interface

Hi,

I was reading in AN-B-001 about how to use the DA14580 in SPI Master mode to boot from an external device. Is there a suggested EEPROM or flash chip to be used in this mode?

Thanks!

Hi modred,

Hi modred,

in principle any I2C EEPROM can be used.
e.g. WinBond W25X10CL or ST M24M01.

Best regards, Dialog Support

Hello,

Hello,

Are the external pull-up needed for booting from that memory?

Hi Rofe,

Hi Rofe,

I you should connect pull ups onto the I2C interface.
We have selected to used 4.3KOhm as a compromise between power consumption and the max specified 5.6KOhm.

Can you suggest SPI EEPROM's.

Can you suggest SPI EEPROM's. Those listed are I2C.
