Hello,

I have the problem that I cannot erase the EEPROM completely. I connect via JTAG and use the EEPROM programmer. If I erase everything with 0x00 then the fields 0x00 to 0x80 are 0x00. However, from 0x80 to 0x100 the field are still 0xFF. this pattern is repeating itself.

As EEPROM I use the 24LC512 from Microchip with 512 kbit.

Hello, I'm looking at the SLG46826 for a new design. I'm running the supply from 2 super caps , so I might have some supply impedance constraints. Can you give me an approximate peak current the device takes when you write to EEPROM (emulated) ? I can always add some hold up capacitance, just need to get a rough figure of merit for the peak/duration so I can size that. I know some EEPROM take 4-5mA or higher, so just want to check. I couldn't see this in the datasheet. Thanks Vincent.

Hi Dialog Team,

we are planning to use an external I2C EEPROM (ST M24256) in our design. I have read through AN-B-001, AN-B-023 and UM-B-012, now I want to make sure I understand the following correctly:

1. The ST M24256 EEPROM has a page size of 64 byte. The default page size of the DA14580 is 256 byte. My understanding is that we have to use a secondary bootloader to change the page size to 64 byte. Is that correct?

2. The default I2C clock when booting from an external peripheral is 100 kHz. Am I correct in assuming that I can increase the clock rate (e.g. to 400 kHz) when using a secondary bootloader?

Thank you!
