Problem with a flash memory

Hello everyone,

my goal is to control a device via BT by using a mobile phone or a Tablet. According to my investigations, DA14580 consumes ultra low-power, maybe the lowest one compared to the others, and this is what I am looking for. The point is it doesn't have a flash memory, so I was wondering about the best architecture. Can I use an external flash memory with SPI interface? It could be a good, easy solution, but my main goal is not to consume power at all. Can I use an external ultra-low power microcontroller? It could be also, but extra hardware and extra efforts. So what's the best solution?

Thanks in advance

Hi there, you can use

你好,你可以使用外部FLASH DA14580 or look at the DA14583 that we are just releasing which has FLASH inside. THe DA14583 will be on Digikey within the next week (SDK is available now). BR JE_Dialog

What about the consumed

What about the consumed current? Is it like the DA14580?

Hi there, yes, it is

Hi there, yes, it is essentially same device : the updated figures are in the datasheet that you can download.THe FLASH is typically only used during boot (not execute) so has very little impact on the low energy consumption... BR JE_Dialog
