Does a Unique ID exists for a LPC18S37?

nxp68994 — Tue, 19 Mar 2019 15:13:59 GMT

The user manual for the LPC18S37 (UM10430) list the feature on page 14:

Unique ID for each device.
But the Unique ID is never referenced in the entire manual. My question: does a Unique ID exist in ROM code of the LPC18S37 which can be used a serial number?

Thanks

Hi Wolfgang Kramper,

Thank you for your interest in NXP Semiconductor products and

Q1) My question: does a Unique ID exist in ROM code of the LPC18S37 which can be used a serial number?

-- No, you can read the unique part ID by referring to Fig 1.

Hi Jeremyzhou,

I found it at “5.7.13 Read device serial number”.

Thank you!
