LPC11U35 EEPROM

peter_furtner — Tue, 22 Nov 2016 15:27:36 GMT

Our customer PHOENIX is using the EEPROM of the LPC11U35.

Now they have a few questions on this EEPROM

- What is the physical address of the EEPROM?

- How can they access this Memory via the Debugger?

- Can they download data via SWD?

Thanks for your Response.

Peter

Hi Peter,

The EEPROM is be invisible to the user, it seems like a external EEPROM chip, and write/read operations are executed by using the corresponding command through I2C or SPI interface.

So the integrated EEPROM can't programmed by the programmed through the SWD interface.

Hope it helps.
Have a great day,

Hi Ping,

what is the technical reason for „hiding“ the EEPROM from the user?

The problem that the customer has is that they need to download configuration information before they start the device for the first time.

So they are looking for ways to do this. What is our recommended way for boot-configuring the EEPROM.

Regards,

Peter

Hi Peter,

The customer can crate a simple demo which is used to program some configuration information to the EEPROM by using IAP commands, and the demo is able to be programmed to the MCU via USB MSC ISP mode.

And I think the approach is good for the mass-manufacture.
Have a great day,
